Endpoint and EDR Ecosystem Connectors in Microsoft Sentinel
Most SOCs operate in mixed endpoint environments. Even if Microsoft Defender for Endpoint is your primary EDR, you may still run Cisco Secure Endpoint, WithSecure Elements, Knox, or Lookout in specific regions, subsidiaries, mobile fleets, or regulatory enclaves. The goal is not to replace any tool, but to standardize how signals become detections and response actions. This article explains an engineering-first approach: ingestion correctness, schema normalization, entity mapping, incident merging, and cross-platform response orchestration. Think of these connectors as four different lenses on endpoint risk. Two provide classic EDR detections (Cisco, WithSecure). Two provide mobile security and posture signals (Knox, Lookout). The highest-fidelity outcomes come from correlating them with Microsoft signals (Defender for Endpoint device telemetry, Entra ID sign-ins, and threat intelligence). Cisco Secure Endpoint Typical signal types include malware detections, exploit prevention events, retrospective detections, device isolation actions, and file/trajectory context. Cisco telemetry is often hash-centric (SHA256, file reputation) which makes it excellent for IOC matching and cross-EDR correlation. WithSecure Elements WithSecure Elements tends to provide strong behavioral detections and ransomware heuristics, often including process ancestry and behavioral classification. It complements hash-based detections by providing behavior and incident context that can be joined to Defender process events. Samsung Knox Asset Intelligence Knox is posture-heavy. Typical signals include compliance state, encryption status, root/jailbreak indicators, patch level, device model identifiers and policy violations. This data is extremely useful for identity correlation: it helps answer whether a successful sign-in came from a device that should be trusted. Lookout Mobile Threat Defense Lookout focuses on mobile threats such as malicious apps, phishing, risky networks (MITM), device compromise indicators, and risk scores. Lookout signals are critical for identity attack chains because mobile phishing is often the precursor to token theft or credential reuse. 2. Ingestion architecture: from vendor API to Sentinel tables Most third‑party connectors are API-based. In production, treat ingestion as a pipeline with reliability requirements. The standard pattern is vendor API → connector runtime (codeless connector or Azure Function) → DCE → DCR transform → Log Analytics table. Key engineering controls: Secrets and tokens should be stored in Azure Key Vault where supported; rotate and monitor auth failures. Use overlap windows (poll slightly more than the schedule interval) and deduplicate by stable event IDs. Use DCR transforms to normalize fields early (device/user/IP/severity) and to filter obviously low-value noise. Monitor connector health and ingestion lag; do not rely on ‘Connected’ status alone. Ingestion health checks (KQL) // Freshness & lag per connector table (adapt table names to your workspace) let lookback = 24h union isfuzzy=true (<CiscoTable> | extend Source="Cisco"), (<WithSecureTable> | extend Source="WithSecure"), (<KnoxTable> | extend Source="Knox"), (<LookoutTable> | extend Source="Lookout") | where TimeGenerated > ago(lookback) | summarize LastEvent=max(TimeGenerated), Events=count() by Source | extend IngestDelayMin = datetime_diff("minute", now(), LastEvent) | order by IngestDelayMin desc // Schema discovery (run after onboarding and after connector updates) Cisco | take 1 | getschema WithSecureTable | take 1 | getschema Knox | take 1 | getschema Lookout | take 1 | getschema 3. Normalization: make detections vendor-agnostic The most common failure mode in multi-EDR SOCs is writing separate rules per vendor. Instead, build one normalization function that outputs a stable schema. Then write rules once. Recommended canonical fields: Vendor, AlertId, EventTime, SeverityNormalized DeviceName (canonical), AccountUpn (canonical), SourceIP FileHash (when applicable), ThreatName/Category CorrelationKey (stable join key such as DeviceName + FileHash or DeviceName + AlertId) // Example NormalizeEndpoint() pattern. Replace column_ifexists(...) mappings after getschema(). let NormalizeEndpoint = () { union isfuzzy=true ( Cisco | extend Vendor="Cisco" | extend DeviceName=tostring(column_ifexists("hostname","")), AccountUpn=tostring(column_ifexists("user","")), SourceIP=tostring(column_ifexists("ip","")), FileHash=tostring(column_ifexists("sha256","")), ThreatName=tostring(column_ifexists("threat_name","")), SeverityNormalized=tolower(tostring(column_ifexists("severity",""))) ), ( WithSecure | extend Vendor="WithSecure" | extend DeviceName=tostring(column_ifexists("hostname","")), AccountUpn=tostring(column_ifexists("user","")), SourceIP=tostring(column_ifexists("ip","")), FileHash=tostring(column_ifexists("file_hash","")), ThreatName=tostring(column_ifexists("classification","")), SeverityNormalized=tolower(tostring(column_ifexists("risk_level",""))) ), ( Knox | extend Vendor="Knox" | extend DeviceName=tostring(column_ifexists("device_id","")), AccountUpn=tostring(column_ifexists("user","")), SourceIP="", FileHash="", ThreatName=strcat("Device posture: ", tostring(column_ifexists("compliance_state",""))), SeverityNormalized=tolower(tostring(column_ifexists("risk",""))) ), ( Lookout | extend Vendor="Lookout" | extend DeviceName=tostring(column_ifexists("device_id","")), AccountUpn=tostring(column_ifexists("user","")), SourceIP=tostring(column_ifexists("source_ip","")), FileHash="", ThreatName=tostring(column_ifexists("threat_type","")), SeverityNormalized=tolower(tostring(column_ifexists("risk_level",""))) ) | extend CorrelationKey = iff(isnotempty(FileHash), strcat(DeviceName, "|", FileHash), strcat(DeviceName, "|", ThreatName)) | project TimeGenerated, Vendor, DeviceName, AccountUpn, SourceIP, FileHash, ThreatName, SeverityNormalized, CorrelationKey, * } 4. Entity mapping and incident merging Sentinel’s incident experience improves dramatically when alerts include entity mapping. Map Host, Account, IP, and File (hash) where possible. Incident grouping should merge alerts by DeviceName and AccountUpn within a reasonable window (e.g., 6–24 hours) to avoid alert storms. 5. Correlation patterns that raise confidence High-confidence detections come from confirmation across independent sensors. These patterns reduce false positives while catching real compromise chains. 5.1 Multi-vendor confirmation (two EDRs agree) NormalizeEndpoint() | where TimeGenerated > ago(24h) | summarize Vendors=dcount(Vendor), VendorSet=make_set(Vendor, 10) by DeviceName | where Vendors >= 2 5.2 Third-party detection confirmed by Defender process telemetry let tp = NormalizeEndpoint() | where TimeGenerated > ago(6h) | where ThreatName has_any ("powershell","ransom","credential","exploit") | project TPTime=TimeGenerated, DeviceName, AccountUpn, Vendor, ThreatName tp | join kind=inner ( DeviceProcessEvents | where Timestamp > ago(6h) | where ProcessCommandLine has_any ("EncodedCommand","IEX","FromBase64String","rundll32","regsvr32") | project MDETime=Timestamp, DeviceName=tostring(DeviceName), Proc=ProcessCommandLine ) on DeviceName | where MDETime between (TPTime .. TPTime + 30m) | project TPTime, MDETime, DeviceName, Vendor, ThreatName, Proc 5.3 Mobile phishing signal followed by successful sign-in let mobile = NormalizeEndpoint() | where TimeGenerated > ago(24h) | where Vendor == "Lookout" and ThreatName has "phish" | project MTDTime=TimeGenerated, AccountUpn, DeviceName, SourceIP mobile | join kind=inner ( SigninLogs | where TimeGenerated > ago(24h) | where ResultType == 0 | project SigninTime=TimeGenerated, AccountUpn=tostring(UserPrincipalName), IPAddress, AppDisplayName ) on AccountUpn | where SigninTime between (MTDTime .. MTDTime + 30m) | project MTDTime, SigninTime, AccountUpn, DeviceName, SourceIP, IPAddress, AppDisplayName 5.4 Knox posture and high-risk sign-in let noncompliant = NormalizeEndpoint() | where TimeGenerated > ago(7d) | where Vendor=="Knox" and ThreatName has "NonCompliant" | project DeviceName, AccountUpn, KnoxTime=TimeGenerated noncompliant | join kind=inner ( SigninLogs | where TimeGenerated > ago(7d) | where RiskLevelDuringSignIn in ("high","medium") | project SigninTime=TimeGenerated, AccountUpn=tostring(UserPrincipalName), RiskLevelDuringSignIn, IPAddress ) on AccountUpn | where SigninTime between (KnoxTime .. KnoxTime + 2h) | project KnoxTime, SigninTime, AccountUpn, DeviceName, RiskLevelDuringSignIn, IPAddress 6. Response orchestration (SOAR) design Response should be consistent across vendors. Use a scoring model to decide whether to isolate a device, revoke tokens, or enforce Conditional Access. Prefer reversible actions, and log every automation step for audit. 6.1 Risk scoring to gate playbooks let SevScore = (s:string) { case(s=="critical",5,s=="high",4,s=="medium",2,1) } NormalizeEndpoint() | where TimeGenerated > ago(24h) | extend Score = SevScore(SeverityNormalized) | summarize RiskScore=sum(Score), Alerts=count(), Vendors=make_set(Vendor, 10) by DeviceName, AccountUpn | where RiskScore >= 8 | order by RiskScore desc High-severity playbooks typically execute: (1) isolate device via Defender (if onboarded), (2) revoke tokens in Entra ID, (3) trigger Conditional Access block, (4) notify and open ITSM ticket. Medium-severity playbooks usually tag the incident, add watchlist entries, and notify analysts.Threat Intelligence & Identity Ecosystem Connectors
Microsoft Sentinel’s capability can be greatly enhanced by integrating third-party threat intelligence (TI) feeds (e.g. GreyNoise, Team Cymru) with identity and access logs (e.g. OneLogin, PingOne). This article provides a detailed dive into each connector, data types, and best practices for enrichment and false-positive reduction. We cover how GreyNoise (including PureSignal/Scout), Team Cymru, OneLogin IAM, PingOne, and Keeper integrate with Sentinel – including available connectors, ingested schemas, and configuration. We then outline technical patterns for building TI-based lookup pipelines, scoring, and suppression rules to filter benign noise (e.g. GreyNoise’s known scanners), and enrich alerts with context from identity logs. We map attack chains (credential stuffing, lateral movement, account takeover) to Sentinel data, and propose KQL analytics rules and playbooks with MITRE ATT&CK mappings (e.g. T1110: Brute Force, T1595: Active Scanning). The report also includes guidance on deployment (ARM/Bicep examples), performance considerations for high-volume TI ingestion, and comparison tables of connector features. A mermaid flowchart illustrates the data flow from TI and identity sources into Sentinel analytics. All recommendations are drawn from official documentation and industry sources. Threat Intel & Identity Connectors Overview GreyNoise (TI Feed): GreyNoise provides “internet background noise” intelligence on IPs seen scanning or probing the Internet. The Sentinel GreyNoise Threat Intelligence connector (Azure Marketplace) pulls data via GreyNoise’s API into Sentinel’s ThreatIntelligenceIndicator table. It uses a daily Azure Function to fetch indicators (IP addresses and metadata like classification, noise, last_seen) and injects them as STIX-format indicators (Network IPs with provider “GreyNoise”). This feed can then be queried in KQL. Authentication requires a GreyNoise API key and a Sentinel workspace app with Contributor rights. GreyNoise’s goal is to help “filter out known opportunistic traffic” so analysts can focus on real threats. Official docs describe deploying the content pack and workbook template. Ingested data: IP-based indicators (malicious vs. benign scans), classifications (noise, riot, etc.), organization names, last-seen dates. All fields from GreyNoise’s IP lookup (e.g. classification, last_seen) appear in ThreatIntelligenceIndicator.NetworkDestinationIP, IndicatorProvider="GreyNoise", and related fields. Query: ThreatIntelligenceIndicator | where IndicatorProvider == "GreyNoise" | summarize arg_max(TimeGenerated, *) by NetworkDestinationIP This yields the latest GreyNoise record per IP. Team Cymru Scout (TI Context): Team Cymru’s PureSignal™ Scout is a TI enrichment platform. The Team Cymru Scout connector (via Azure Marketplace) ingests contextual data (not raw logs) about IPs, domains, and account usage into Sentinel custom tables. It runs via an Azure Function that, given IP or domain inputs, populates tables like Cymru_Scout_IP_Data_* and Cymru_Scout_Domain_Data_CL. For example, an IP query yields multiple tables: Cymru_Scout_IP_Data_Foundation_CL, ..._OpenPorts_CL, ..._PDNS_CL, etc., containing open ports, passive DNS history, X.509 cert info, fingerprint data, etc. This feed requires a Team Cymru account (username/password) to access the Scout API. Data types: Structured TI metadata by IP/domain. No native ThreatIndicator insertion; instead, analysts query these tables to enrich events (e.g. join on SourceIP). The Sentintel TechCommunity notes that Scout “enriches alerts with real-time context on IPs, domains, and adversary infrastructure” and can help “reduce false positives”. OneLogin IAM (Identity Logs): The OneLogin IAM solution (Microsoft Sentinel content pack) ingests OneLogin platform events and user info via OneLogin’s REST API. Using the Codeless Connector Framework, it pulls from OneLogin’s Events API and Users API, storing data in custom tables OneLoginEventsV2_CL and OneLoginUsersV2_CL. Typical events include user sign-ins, MFA actions, app accesses, admin changes, etc. Prerequisites: create an OpenID Connect app in OneLogin (for client ID/secret) and register it in Azure (Global Admin). The connector queries hourly (or on schedule), within OneLogin’s rate limit of 5000 calls/hour. Data mapping: OneLoginEventsV2_CL (CL suffix indicates custom log) holds event records (time, user, IP, event type, result, etc.); OneLoginUsersV2_CL contains user account attributes. These can be joined or used in analytics. For example, a query might look for failed login events: OneLoginEventsV2_CL | where Event_type_s == "UserSessionStart" and Result_s == "Failed" (Actual field names depend on schema.) PingOne (Identity Logs): The PingOne Audit connector ingests audit activity from the PingOne Identity platform via its REST API. It creates the table PingOne_AuditActivitiesV2_CL. This includes administrator actions, user logins, console events, etc. You configure a PingOne API client (Client ID/Secret) and set up the Codeless Connector Framework. Logs are retrieved (with attention to PingOne’s license-based rate limits) and appended to the custom table. Analysts can query, for instance, PingOne_AuditActivitiesV2_CL for events like MFA failures or profile changes. Keeper (Password Vault Logs – optional): Keeper, a password management platform, can forward security events to Sentinel via Azure Monitor. As of latest docs, logs are sent to a custom log table (commonly KeeperLogs_CL) using Azure Data Collection Rules. In Keeper’s guide, you register an Azure AD app (“KeeperLogging”) and configure Azure Monitor data collection; then in the Keeper Admin Console you specify the DCR endpoint. Keeper events (e.g. user logins, vault actions, admin changes) are ingested into the table named (e.g.) Custom-KeeperLogs_CL. Authentication uses the app’s client ID/secret and a monitor endpoint URL. This is a bulk ingest of records, rather than a scheduled pull. Data ingested: custom Keeper events with fields like user, action, timestamp. Keeper’s integration is essentially via Azure Monitor (in the older Azure Sentinel approach). Connector Configuration & Data Ingestion Authentication and Rate Limits: Most connectors require API keys or OAuth credentials. GreyNoise and Team Cymru use single keys/credentials, with the Azure Function secured by a Managed Identity. OneLogin and PingOne use client ID/secret and must respect their API limits (OneLogin ~5k calls/hour; PingOne depends on licensing). GreyNoise’s enterprise API allows bulk lookups; the community API is limited (10/day for free), so production integration requires an Enterprise plan. Sentinel Tables: Data is inserted either into built-in tables or custom tables. GreyNoise feeds the ThreatIntelligenceIndicator table, populating fields like NetworkDestinationIP and ThreatSeverity (higher if classified “malicious”). Team Cymru’s Scout connector creates many Cymru_Scout_*_CL tables. OneLogin’s solution populates OneLoginEventsV2_CL and OneLoginUsersV2_CL. PingOne yields PingOne_AuditActivitiesV2_CL. Keeper logs appear in a custom table (e.g. KeeperLogs_CL) as shown in Keeper’s guide. Note: Sentinel’s built-in identity tables (IdentityInfo, SigninLogs) are typically for Microsoft identities; third-party logs can be mapped to them via parsers or custom analytic rules but by default arrive in these custom tables. Data Types & Schema: Threat Indicators: In ThreatIntelligenceIndicator, GreyNoise IPs appear as NetworkDestinationIP with associated fields (e.g. ThreatSeverity, IndicatorProvider="GreyNoise", ConfidenceScore, etc.). (Future STIX tables may be used after 2025.) Custom CL Logs: OneLogin events may include fields such as user_id_s, user_login_s, client_ip_s, event_time, etc. (The published parser issues indicate fields like app_name_s, role_id_d, etc.) PingOne logs include eventType, user, clientIP, result. Keeper logs contain Action, UserName, etc. These raw fields can be normalized in analytic rules or parsed by data transformations. Identity Info: Although not directly ingested, identity attributes from OneLogin/PingOne (e.g. user roles, group IDs) could be periodically fetched and synced to Sentinel (via custom logic) to populate IdentityInfo records, aiding user-centric hunts. Configuration Steps : GreyNoise: In Sentinel Content Hub, install the GreyNoise ThreatIntel solution. Enter your GreyNoise API key when prompted. The solution deploys an Azure Function (requires write access to Functions) and sets up an ingestion schedule. Verify the ThreatIntelligenceIndicator table is receiving GreyNoise entries Team Cymru: From Marketplace install “Team Cymru Scout”. Provide Scout credentials. The solution creates an Azure Function app. It defines a workflow to ingest or lookup IPs/domains. (Often, analysts trigger lookups rather than scheduled ingestion, since Scout is lookup-based.) Ensure roles: the Function’s managed identity needs Sentinel contributor rights. OneLogin: Use the Data Connectors UI. Authenticate OneLogin by creating a new Sentinel Web API authentication (with OneLogin’s client ID/secret). Enable both “OneLogin Events” and “OneLogin Users”. No agent is needed. After setup, data flows into OneLoginEventsV2_CL. PingOne: Similarly, configure the PingOne connector. Use the PingOne administrative console to register an OAuth client. In Sentinel’s connector blade, enter the client ID/secret and specify desired log types (Audit, maybe IDP logs). Confirm PingOne_AuditActivitiesV2_CL populates hourly. Keeper: Register an Azure AD app (“KeeperLogging”) and assign it Monitoring roles (Publisher/Contributor) to your workspace and data collection endpoint. Create an Azure Data Collection Rule (DCR) and table (e.g. KeeperLogs_CL). In Keeper’s Admin Console (Reporting & Alerts → Azure Monitor), enter the tenant ID, client ID/secret, and the DCR endpoint URL (format: https://<DCE>/dataCollectionRules/<DCR_ID>/streams/<table>?api-version=2023-01-01). Keeper will then push logs. KQL Lookup: To enrich a Sentinel event with these feeds, you might write: OneLoginEventsV2_CL | where EventType == "UserLogin" and Result == "Success" | extend UserIP = ClientIP_s | join kind=inner ( ThreatIntelligenceIndicator | where IndicatorProvider == "GreyNoise" and ThreatSeverity >= 3 | project NetworkDestinationIP, Category ) on $left.UserIP == $right.NetworkDestinationIP This joins OneLogin sign-ins with GreyNoise’s list of malicious scanners. Enrichment & False-Positive Reduction IOC Enrichment Pipelines: A robust TI pipeline in Sentinel often uses Lookup Tables and Functions. For example, ingested TI (from GreyNoise or Team Cymru) can be stored in reference data or scheduled lookup tables to enrich incoming logs. Patterns include: - Normalization: Normalize diverse feeds into common STIX schema fields (e.g. all IPs to NetworkDestinationIP, all domains to DomainName) so rules can treat them uniformly. - Confidence Scoring: Assign a confidence score to each indicator (from vendor or based on recency/frequency). For GreyNoise, for instance, you might use classification (e.g. “malicious” vs. “benign”) and history to score IP reputation. In Sentinel’s ThreatIntelligenceIndicator.ConfidenceScore field you can set values (higher for high-confidence IOCs, lower for noisy ones). - TTL & Freshness: Some indicators (e.g. active C2 domains) expire, so setting a Time-To-Live is critical. Sentinel ingestion rules or parsers should use ExpirationDateTime or ValidUntil on indicators to avoid stale IOCs. For example, extend ValidUntil only if confidence is high. - Conflict Resolution: When the same IOC comes from multiple sources (e.g. an IP in both GreyNoise and TeamCymru), you can either merge metadata or choose the highest confidence. One approach: use the highest threat severity from any source. Sentinel’s ThreatType tags (e.g. malicious-traffic) can accommodate multiple providers. False-Positive Reduction Techniques: - GreyNoise Noise Scoring: GreyNoise’s primary utility is filtering. If an IP is labeled noise=true (i.e. just scanning, not actively malicious), rules can deprioritize alerts involving that IP. E.g. suppress an alert if its source IP appears in GreyNoise as benign scanner. - Team Cymru Reputation: Use Scout data to gauge risk; e.g. if an IP’s open port fingerprint or domain history shows no malicious tags, it may be low-risk. Conversely, known hostile IP (e.g. seen in ransomware networks) should raise alert level. Scout’s thousands of context tags help refine a binary IOC. - Contextual Identity Signals: Leverage OneLogin/PingOne context to filter alerts. For instance, if a sign-in event is associated with a high-risk location (e.g. new country) and the IP is a GreyNoise scan, flag it. If an IP is marked benign, drop or suppress. Correlate login failures: if a single IP causes many failures across multiple users, it might be credential stuffing (T1110) – but if that IP is known benign scanner, consider it low priority. - Thresholding & Suppression: Build analytic suppression rules. Example: only alert on >5 failed logins in 5 min from IP and that IP is not noise. Or ignore DNS queries to domains that TI flags as benign/whitelisted. Apply tag-based rules: some connectors allow tagging known internal assets or trusted scan ranges to avoid alerts. Use GreyNoise to suppress alerts: SecurityEvent | where EventID == 4625 and Account != "SYSTEM" | join kind=leftanti ( ThreatIntelligenceIndicator | where IndicatorProvider == "GreyNoise" and Classification == "benign" | project NetworkSourceIP ) on $left.IPAddress == $right.NetworkSourceIP This rule filters out Windows 4625 login failures originating from GreyNoise-known benign scanners. Identity Attack Chains & Detection Rules Modern account attacks often involve sequential activities. By combining identity logs with TI, we can detect advanced patterns. Below are common chains and rule ideas: Credential Stuffing (MITRE T1110): Often seen as many login failures followed by a success. Detection: Look for multiple failed OneLogin/PingOne sign-ins for the same or different accounts from a single IP, then a success. Enrich with GreyNoise: if the source IP is in GreyNoise (indicating scanning), raise severity. Rule: let SuspiciousIP = OneLoginEventsV2_CL | where EventType == "UserSessionStart" and Result == "Failed" | summarize CountFailed=count() by ClientIP_s | where CountFailed > 5; OneLoginEventsV2_CL | where EventType == "UserSessionStart" and Result == "Success" and ClientIP_s in (SuspiciousIP | project ClientIP_s) | join kind=inner ( ThreatIntelligenceIndicator | where ThreatType == "ip" | extend GreyNoiseClass = tostring(Classification) | project IP=NetworkSourceIP, GreyNoiseClass ) on $left.ClientIP_s == $right.IP | where GreyNoiseClass == "malicious" | project TimeGenerated, Account_s, ClientIP_s, GreyNoiseClass Tactics: Initial Access (T1110) – Severity: High. Account Takeover / Impossible Travel (T1198): Sign-ins from unusual geographies or devices. Detection: Compare user’s current sign-in location against historical baseline. Use OneLogin/PingOne logs: if two logins by same user occur in different countries with insufficient time to travel, trigger. Enrich: if the login IP is also known infrastructure (Team Cymru PDNS, etc.), raise alert. Rule: PingOne_AuditActivitiesV2_CL | where EventType_s == "UserLogin" | extend loc = tostring(City_s) + ", " + tostring(Country_s) | sort by TimeGenerated desc | partition by User_s ( where TimeGenerated < ago(24h) // check last day | summarize count(), min(TimeGenerated), max(TimeGenerated) ) | where max_TimeGenerated - min_TimeGenerated < 1h and count_>1 and (range(loc) contains ",") | project User_s, TimeGenerated, loc (This pseudo-query checks multiple locations in <1 hour.) Tactics: Reconnaissance / Initial Access – Severity: Medium. Lateral Movement (T1021): Use of an account on multiple systems/apps. Detection: Two or more distinct application/service authentications by same user within a short time. Use OneLogin app-id fields or audit logs for access. If these are followed by suspicious network activity (e.g. contacting C2 via GreyNoise), escalate. Tactics: Lateral Movement – Severity: High. Privilege Escalation (T1098): If an admin account is changed or MFA factors reset in OneLogin/PingOne, especially after anomalous login. Detection: Monitor OneLogin admin events (“User updated”, “MFA enrolled/removed”). Cross-check the actor’s IP against threat feeds. Tactics: Credential Access – Severity: High. Analytics Rules (KQL) Below are six illustrative Sentinel analytics rules combining TI and identity logs. Each rule shows logic, tactics, severity, and MITRE IDs. (Adjust field names per your schemas and normalize CL tables as needed.) Multiple Failed Logins from Malicious Scanner (T1110) – High severity. Detect credential stuffing by identifying >5 failed login attempts from the same IP, where that IP is classified as malicious by GreyNoise. let BadIP = OneLoginEventsV2_CL | where EventType == "UserSessionStart" and Result == "Failed" | summarize attempts=count() by SourceIP_s | where attempts >= 5; OneLoginEventsV2_CL | where EventType == "UserSessionStart" and Result == "Success" and SourceIP_s in (BadIP | project SourceIP_s) | join ( ThreatIntelligenceIndicator | where IndicatorProvider == "GreyNoise" and ThreatSeverity >= 4 | project MaliciousIP=NetworkDestinationIP ) on $left.SourceIP_s == $right.MaliciousIP | extend AttackFlow="CredentialStuffing", MITRE="T1110" | project TimeGenerated, UserName_s, SourceIP_s, MaliciousIP Logic: Correlate failed-then-success login from same IP plus GreyNoise-malign classification. Impossible Travel / Anomalous Geo (T1198) – Medium severity. A user signs in from two distant locations within an hour. // Get last two logins per user let lastLogins = PingOne_AuditActivitiesV2_CL | where EventType_s == "UserLogin" and Outcome_s == "Success" | sort by TimeGenerated desc | summarize first_place=arg_max(TimeGenerated, City_s, Country_s, SourceIP_s, TimeGenerated) by User_s; let prevLogins = PingOne_AuditActivitiesV2_CL | where EventType_s == "UserLogin" and Outcome_s == "Success" | sort by TimeGenerated desc | summarize last_place=arg_min(TimeGenerated, City_s, Country_s, SourceIP_s, TimeGenerated) by User_s; lastLogins | join kind=inner prevLogins on User_s | extend dist=geo_distance_2points(first_place_City_s, first_place_Country_s, last_place_City_s, last_place_Country_s) | where dist > 1000 and (first_place_TimeGenerated - last_place_TimeGenerated) < 1h | project Time=first_place_TimeGenerated, User=User_s, From=last_place_Country_s, To=first_place_Country_s, MITRE="T1198" Logic: Compute geographic distance between last two logins; flag if too far too fast. Suspicious Admin Change (T1098) – High severity. Detect a change to admin settings (like role assign or MFA reset) via PingOne, from a high-risk IP (Team Cymru or GreyNoise) or after failed logins. PingOne_AuditActivitiesV2_CL | where EventType_s in ("UserMFAReset", "UserRoleChange") // example admin events | extend ActorIP = tostring(InitiatingIP_s) | join ( ThreatIntelligenceIndicator | where ThreatSeverity >= 3 | project BadIP=NetworkDestinationIP ) on $left.ActorIP == $right.BadIP | extend MITRE="T1098" | project TimeGenerated, ActorUser_s, Action=EventType_s, ActorIP Logic: Raise if an admin action originates from known bad IP. Malicious Domain Access (T1498): Medium severity. Internal logs (e.g. DNS or Web proxy) show access to a domain listed by Team Cymru Scout as C2 or reconnaissance. DeviceDnsEvents | where QueryType == "A" | join kind=inner ( Cymru_Scout_Domain_Data_CL | where ThreatTag_s == "Command-and-Control" | project DomainName_s ) on $left.QueryText == $right.DomainName_s | extend MITRE="T1498" | project TimeGenerated, DeviceName, QueryText Logic: Correlate internal DNS queries with Scout’s flagged C2 domains. (Requires that domain data is ingested or synced.) Brute-Force Firewall Blocked IP (T1110): Low to Medium severity. Firewall logs show an IP blocked for many attempts, and that IP is not noise per GreyNoise (i.e., malicious scanner). AzureDiagnostics | where Category == "NetworkSecurityGroupFlowEvent" and msg_s contains "DIRECTION=Inbound" and Action_s == "Deny" | summarize attemptCount=count() by IP = SourceIp_s, FlowTime=bin(TimeGenerated, 1h) | where attemptCount > 50 | join kind=leftanti ( ThreatIntelligenceIndicator | where IndicatorProvider == "GreyNoise" and Classification == "benign" | project NoiseIP=NetworkDestinationIP ) on $left.IP == $right.NoiseIP | extend MITRE="T1110" | project IP, attemptCount, FlowTime Logic: Many inbound denies (possible brute force) from an IP not whitelisted by GreyNoise. New Device Enrolled (T1078): Low severity. A user enrolls a new device or location for MFA after unusual login. OneLoginEventsV2_CL | where EventType == "NewDeviceEnrollment" | join kind=inner ( OneLoginEventsV2_CL | where EventType == "UserSessionStart" and Result == "Success" | top 1 by TimeGenerated asc // assume prior login | project User_s, loginTime=TimeGenerated, loginIP=ClientIP_s ) on User_s | where loginIP != DeviceIP_s | extend MITRE="T1078" | project TimeGenerated, User_s, DeviceIP_s, loginIP Logic: Flag if new device added (strong evidence of account compromise). Note: The above rules are illustrative. Tune threshold values (e.g. attempt counts) to your environment. Map the event fields (EventType, Result, etc.) to your actual schema. Use Severity mapping in rule configs as indicated and tag with MITRE IDs for context. TI-Driven Playbooks and Automation Automated response can amplify TI. Patterns include: - IOC Blocking: On alert (e.g. suspicious IP login), an automation runbook can call Azure Firewall, Azure Defender, or external firewall APIs to block the offending IP. For instance, a Logic App could trigger on the analytic alert, use the TI feed IP, and call AzFWNetworkRule PowerShell to add a deny rule. - Enrichment Workflow: After an alert triggers, an Azure Logic App playbook can enrich the incident by querying TI APIs. E.g., given an IP from the alert, call GreyNoise API or Team Cymru Scout API in real-time (via HTTP action), add the classification into incident details, and tag the incident accordingly (e.g. GreyNoiseStatus: malicious). This adds context for the analyst. - Alert Suppression: Implement playbook-driven suppression. For example, an alert triggered by an external IP can invoke a playbook that checks GreyNoise; if the IP is benign, the playbook can auto-close the alert or mark as false-positive, reducing analyst load. - Automated TI Feed Updates: Periodically fetch open-source or commercial TI and use a playbook to push new indicators into Sentinel’s TI store via the Graph API. - Incident Enrichment: On incident creation, a playbook could query OneLogin/PingOne for additional user details (like department or location via their APIs) and add as note in the incident. Performance, Scalability & Costs TI feeds and identity logs can be high-volume. Key considerations: - Data Ingestion Costs: Every log and TI indicator ingested into Sentinel is billable by the GB. Bulk TI indicator ingestion (like GreyNoise pulling thousands of IPs/day) can add storage costs. Use Sentinel’s Data Collection Rules (DCR) to apply ingestion-time filters (e.g. only store indicators above a confidence threshold) to reduce volume. GreyNoise feed is typically modest (since it’s daily, maybe thousands of IPs). Identity logs (OneLogin/PingOne) depend on org size – could be megabytes per day. Use sentinel ingestion sl analytic filters to drop low-value logs. - Query Performance: Custom log tables (OneLogin, PingOne, KeeperLogs_CL) can grow large. Periodically archive old data (e.g. export >90 days to storage, then purge). Use materialized views or scheduled summary tables for heavy queries (e.g. pre-aggregate hourly login counts). For threat indicator tables, leverage built-in indices on IndicatorId and NetworkIP for fast joins. Use project-away _* to remove metadata from large join queries. - Retention & Storage: Configure retention per table. If historical TI is less needed, set shorter retention. Use Azure Monitor’s tiering/Archive for seldom-used data. For large TI volumes (e.g. feeding multiple TIPs), consider using Sentinel Data Lake (or connecting Log Analytics to ADLS Gen2) to offload raw ingest cheaply. - Scale-Out Architecture: For very large environments, use multiple Sentinel workspaces (e.g. regional) and aggregate logs via Azure Lighthouse or Sentinel Fusion. TI feeds can be shared: one workspace collects TI, then distribute to others via Azure Sentinel’s TI management (feeds can be published and shared cross-workspaces). - Connector Limits: API rate limits dictate update frequency. Schedule connectors accordingly (e.g. daily for TI, hourly for identity events). Avoid hourly pulls of already static data (users list can be daily). For OneLogin/PingOne, use incremental tokens or webhooks if possible to reduce load. - Monitoring Health: Use Sentinel’s Log Analytics and Monitor metrics to track ingestion volume and connector errors. For example, monitor the Functions running GreyNoise/Scout for failures or throttling. Deployment Checklist & Guide Prepare Sentinel Workspace: Ensure a Log Analytics workspace with Sentinel enabled. Record the workspace ID and region. Register Applications: In Azure AD, create and note any Service Principal needed for functions or connectors (e.g. a Sentinel-managed identity for Functions). In each vendor portal, register API apps and credentials (OneLogin OIDC App, PingOne API client, Keeper AD app). Network & Security: If needed, configure firewall rules to allow outbound to vendor APIs. Install Connectors: In Sentinel Content Hub or Marketplace, install the solutions for GreyNoise TI, Team Cymru Scout, OneLogin IAM, PingOne. Follow each wizard to input credentials. Verify the “Data Types” (Logs, Alerts, etc.) are enabled. Create Tables & Parsers (if manual): For Keeper or unsupported logs, manually create custom tables (via DCR in Azure portal). Import JSON to define fields as shown in Keeper’s docs Test Data Flow: After each setup, wait 1–24 hours and run a simple query on the destination table (e.g. OneLoginEventsV2_CL | take 5) to confirm ingestion. Deploy Ingestion Rules: Use Sentinel Threat intelligence ingestion rules to fine-tune feeds (e.g. mark high-confidence feeds to extend expiration). Optionally tag/whitelist known good. Configure Analytics: Enable or create rules using the KQL above. Place them in the correct threat hunting or incident rule categories (Credential Access, Lateral Movement, etc.). Assign appropriate alert severity. Set up Playbooks: For automated actions (alert enrichment, IOC blocking), create Logic App playbooks. Test with mock alerts (dry run) to ensure correct API calls. Tuning & Baseline: After initial alerts, tune queries (thresholds, whitelists) to reduce noise. Maintain suppression lists (e.g. internal pentest IPs). Use the MITRE mapping in rule details for clarity. Documentation & Training: Document field mappings (e.g. OneLoginEvents fields), and train SOC staff on new TI-enriched alert fields.

Question malware autodelete
A malware like Trojan:Win32/Wacatac.C!ml can download other malware, this other malware can perform the malicious action, this malware can delete itself and in the next scan of antivirus free this malware that deleted itself will not have any trace and will not be detected by the scan?Integrating Proofpoint and Mimecast Email Security with Microsoft Sentinel
Microsoft Sentinel can ingest rich email security telemetry from Proofpoint and Mimecast to power advanced phishing detection. The Proofpoint On Demand (POD) Email Security and Proofpoint Targeted Attack Protection (TAP) connectors pull threat logs (quarantines, spam, phishing attempts) and user click data into Sentinel. Similarly, the Mimecast Secure Email Gateway connector ingests detailed mail flow and targeted-threat logs (attachment/URL scans, impersonation events). These integrations use Azure-hosted ingestion (via Logic Apps or Azure Functions) and the new Codeless Connector framework to call vendor APIs on a schedule. The result is a consolidated dataset in Sentinel’s Log Analytics, enabling correlated alerting and hunting across email, identity, and endpoint signals. Figure: Phishing emails are processed by Mimecast’s gateway and Proofpoint POD/TAP services. Security logs (delivery/quarantine events, malicious attachments/links, user clicks) flow into Microsoft Sentinel. In Sentinel, these mail signals are correlated with identity (Azure AD), endpoint (Defender) and network telemetry for end-to-end phishing detection. Proofpoint POD (Email Protection) Connector The Proofpoint POD connector ingests core email protection logs. It creates two tables, ProofpointPODMailLog_CL and ProofpointPODMessage_CL. These logs include per-message metadata (senders, recipients, subject, message size, timestamps), threat scores (spamScore, phishScore, malwareScore, impostorScore), and attachment details (number of attachments, names, hash values and sandbox verdicts). Quarantine actions are recorded (quarantine folder/rule) and malicious indicators (URL or file hash) and campaign IDs are tagged in the threatsInfoMap field. For example, each ProofpointPODMessage_CL record may carry a sender_s (sender email domain hashed), recipient list, subject, and any detected threat type (Phish/Malware/Spam/Impostor) with associated threat hash or URL. Deployment: Proofpoint POD uses Sentinel’s codeless connector (an Azure Function behind the scenes). You must provide Proofpoint API credentials (Cluster ID and API token) in the connector UI. The connector periodically calls the Proofpoint SIEM API to fetch new log events (typically in 1–2 hour batches). The data lands in the above tables. (Older custom logic-app approaches similarly parse JSON output from the /v2/siem/messages endpoints.) Proofpoint TAP (Targeted Attack Protection) Connector Proofpoint TAP provides user-click and message-delivery events. Its connector creates four tables: ProofPointTAPMessagesDeliveredV2_CL, ProofPointTAPMessagesBlockedV2_CL, ProofPointTAPClicksPermittedV2_CL, and ProofPointTAPClicksBlockedV2_CL. The message tables report emails with detected threats (URL or attachment defense) that were delivered or blocked by TAP. They include the same fields as POD (message GUID, sender, recipients, subject, threat campaign ID, scores, attachments info). The click tables log when users click on URLs: each record has the URL, click timestamp (clickTime), the user’s IP (clickIP), user-agent, the message GUID, and the threat ID/category. These fields allow you to see who clicked which malicious link and when. As the connector description notes, these logs give “visibility into Message and Click events in Microsoft Sentinel” for hunting. Deployment: The TAP connector also uses the codeless framework. You supply a TAP API service principal and secret (proofpoint SIEM API credentials) in the Sentinel content connector. The function app calls TAP’s /v2/siem/clicks/blocked, /permitted, /messages/blocked, and /delivered endpoints. The Proofpoint SIEM API limits queries to 1-hour windows and 7-day history, with no paging (all events in the interval are returned). (A Logic App approach could also be used, as shown in the Tech Community blog: one HTTP GET per event type and a JSON Parse before sending to Log Analytics.) Mimecast Secure Email Gateway Connector The Mimecast connector ingests the Secure Email Gateway (SEG) logs and targeted-threat (TTP) logs. Inbound, outbound and internal mail events from the Mimecast MTA (receipt, processing, delivery stages) are pulled via the API. Typical fields include the unique message ID (aCode), sender, recipient, subject, attachment count/names, and the policy actions or holds (e.g. spam quarantine). For example, the Mimecast “Process” log shows AttCnt, AttNames, and if the message was held (Hld) for review. Delivery logs include the success/failure and TLS details. In addition, Mimecast TTP logs are collected: URL Protect logs (when a user clicks a blocked URL) include the clicked URL (url), category (urlCategory), sender/recipient, and block reason. Impersonation Protect logs capture spoofing detections (e.g. if an internal name is impersonated), with fields like Sender, Recipient, Definition and Action (hold/quarantine). Attachment Protect logs record malicious file detections (filename, hash, threat type). Deployment: Like Proofpoint, Mimecast’s connector uses Azure Functions via the Sentinel content hub. You install the Mimecast solution, open the connector page, then enter Azure app credentials and Mimecast API keys (API Application ID/Key and Access/Secret for the service account). As shown in the deployment guide, you must provide the Azure Subscription, Resource Group, Log Analytics Workspace and the Azure Client (App) ID, Tenant ID and Object ID of the admin performing the setup. On the Mimecast side, you supply the API Base URL (regional), App ID/Secret and user Access/Secret. The connector creates a Function App that polls Mimecast’s SIEM APIs on a cron schedule (default every 30 minutes). You can optionally specify a start date for backfilling up to 7 days of logs. The default tables are MimecastSIEM_CL (for email flow logs) and MimecastDLP_CL (for DLP/TTP events), though custom names can be set. Ingestion Considerations Data Latency: All these connectors are pull-based and typically run on a schedule (often 30–60 minutes). For example, the Proofpoint POD docs note hourly log increments, and Mimecast logs are aggregated every 30 minutes. Expect a delay of up to an hour or more from event occurrence to Sentinel ingestion. Schema Nuances: The APIs often return nested arrays and optional fields. For instance, the Proofpoint blog warns that some JSON fields can be null or vary in type, so the parse schema should account for all possibilities. Similarly, Mimecast logs come in pipe-delimited or JSON format, with values sometimes empty (e.g. no attachments). In KQL, use tostring() or parse_json() on the raw _CL columns, and mv-expand on any multivalue fields (like message parts or threat lists). Table Names: Use the connector’s tables as listed. For Proofpoint: ProofpointPODMailLog_CL and ProofpointPODMessage_CL; for TAP: ProofPointTAPMessagesDeliveredV2_CL, ProofPointTAPMessagesBlockedV2_CL, ProofPointTAPClicksPermittedV2_CL, ProofPointTAPClicksBlockedV2_CL. For Mimecast SEG/TTP: MimecastSIEM_CL (seg logs) and MimecastDLP_CL (TTP logs). API Behavior: The Proofpoint TAP API has no paging. Be aware of timezones (Proofpoint uses UTC) and use the Sentinal ingestion TimeGenerated or event timestamp fields for binning. Detection Engineering and Correlation To detect phishing effectively, we correlate these email logs with identity, endpoint and intel data: Identity (Azure AD): Mail logs contain recipient addresses and (hashed) sender user parts. A common tactic is to correlate SMTP recipients or sender domains with Azure AD user records. For example, join TAP clicks by recipient to the user’s UPN. The Proofpoint logs also include the clicker’s IP (clickIP); we can match that to Azure AD sign-in logs or VPN logs to find which device/location clicked a malicious link. Likewise, anomalous Azure AD sign-ins (impossible travel, MFA failure) after a suspicious email can strengthen the case. Endpoints (Defender): Once a user clicks a bad link or opens a malicious attachment (captured in TAP or Mimecast logs), watch for follow-on behaviors. For instance, use Sentinel’s DeviceSecurityEvents or DeviceProcessEvents to see if that user’s machine launched unusual processes. The threatID or URL hash from email events can be looked up in Defender’s file data. Correlate by username (if available) or IP: if the email log shows a link click from IP X, see if any endpoint alerts or logon events occurred from X around the same time. As the Mimecast integration touts, this enables “correlation across Mimecast events, cloud, endpoint, and network data”. Threat Intelligence: Use Sentinel’s ThreatIntelligenceIndicator tables or Microsoft’s TI feeds to tag known bad URLs/domains in the email logs. For example, join ProofPointTAPClicksBlockedV2_CL on the clicked url against ThreatIntelligenceIndicator (type=URL) to automatically flag hits. Proofpoint’s logs already classify threats (malware/phish) and provide a threatID; one can enrich that with external intel (e.g. check if the hash appears in TI feeds). Mimecast’s URL logs include a urlCategory field, which can be mapped to known malicious categories. Automated playbooks can also pull Intel: e.g. use Sentinel’s TI REST API or Azure Sentinel watchlists containing phishing domains to annotate events. In summary, a robust detection strategy might look like: (1) Identify malicious email events (high phish scores, quarantines, URL clicks). (2) Correlate these events by user with Azure AD logs (did the user log in from a new IP after a phish click?). (3) Correlate with endpoint alerts (Defender found malware on that device). (4) Augment with threat intelligence lookups on URLs and attachments from the email logs. By linking the Proofpoint/Mimecast signals to identity and endpoint events, one can detect the full attack chain from email compromise to endpoint breach. KQL Query Here are representative Kusto queries for common phishing scenarios (adapt table/field names as needed): Malicious URL Click Detection: Identify users who clicked known-malicious URLs. For example, join TAP click logs to TI indicators:This flags any permitted click where the URL matches a known threat indicator. Alternatively, aggregate by domain: let TI = ThreatIntelligenceIndicator | where Active == true and _EntityType == "URL"; ProofPointTAPClicksPermittedV2_CL | where url_s != "" | project ClickTime=TimeGenerated, Recipient=recipient_s, URL=url_s, SenderIP=senderIP_s | join kind=inner TI on $left.URL == TI._Value | project ClickTime, Recipient, URL, Description=TI.Description This flags any permitted click where the URL matches a known threat indicator. Alternatively, aggregate by domain: ProofPointTAPClicksPermittedV2_CL | extend clickedDomain = extract(@"https?://([^/]+)", 1, url_s) | summarize ClickCount=count() by clickedDomain | where clickedDomain has "maliciousdomain.com" or clickedDomain has "phish.example.com" Quarantine Spike (Burst) Detection: Detect sudden spikes in quarantined messages. For example, using POD mail log:This finds hours with an unusually high number of held (quarantined) emails, which may indicate a phishing campaign. You could similarly use ProofPointTAPMessagesBlockedV2_CL. ProofpointPODMailLog_CL | where action_s == "Held" | summarize HeldCount=count() by bin(TimeGenerated, 1h) | order by TimeGenerated desc | where HeldCount > 100 Targeted User Phishing: Find if a specific user received multiple malicious emails. E.g., for user email address removed for privacy reasons:This lists recent phish attempts targeting Username. You might also join with TAP click logs to see if she clicked anything. ProofpointPODMessage_CL | where recipient has "email address removed for privacy reasons" | where array_length(threatsInfoMap) > 0 and threatsInfoMap_classification_s == "Phish" | project TimeGenerated, sender_s, subject_s, threat=threatsInfoMap_threat_s Campaign-Level Analysis: Group emails by Proofpoint campaign ID to see scope of each campaign:This shows each campaign ID with how many unique recipients were hit and one example subject. Combining TAP and POD tables on GUID_s or QID_s can further link click events back to the originating message/campaign. ProofpointPODMessage_CL | mv-expand threatsInfoMap | summarize Recipients=make_set(recipient), Count=dcount(recipient) by CampaignID=threatsInfoMap_campaignId_s | project CampaignID, RecipientCount=Count, Recipients, SampleSubject=any(subject_s) Each query can be refined (for instance, filtering only within a recent time window) and embedded in Sentinel Analytics rules or hunting. The key is using the connectors’ fields – URLs, sender/recipient addresses, campaign IDs – to pivot between email data and other security signals.Cloud Posture + Attack Surface Signals in Microsoft Sentinel (Prisma Cloud + Cortex Xpanse)
Microsoft expanded Microsoft Sentinel’s connector ecosystem with Palo Alto integrations that pull cloud posture, cloud workload runtime, and external attack surface signals into the SIEM, so your SOC can correlate “what’s exposed” and “what’s misconfigured” with “what’s actively being attacked.” Specifically, the Ignite connectors list includes Palo Alto: Cortex Xpanse CCF and Palo Alto: Prisma Cloud CWPP. Why these connectors matter for Sentinel detection engineering Traditional SIEM pipelines ingest “events.” But exposure and posture are just as important as the events—because they tell you which incidents actually matter. Attack surface (Xpanse) tells you what’s reachable from the internet and what attackers can see. Posture (Prisma CSPM) tells you which controls are broken (public storage, permissive IAM, weak network paths). Runtime (Prisma CWPP) tells you what’s actively happening inside workloads (containers/hosts/serverless). In Sentinel, these become powerful when you can join them with your “classic” telemetry (cloud activity logs, NSG flow logs, DNS, endpoint, identity). Result: fewer false positives, faster triage, better prioritization. Connector overview (what each one ingests) 1) Palo Alto Prisma Cloud CSPM Solution What comes in: Prisma Cloud CSPM alerts + audit logs via the Prisma Cloud CSPM API. What it ships with: connector + parser + workbook + analytics rules + hunting queries + playbooks (prebuilt content). Best for: Misconfig alerts: public storage, overly permissive IAM, weak encryption, risky network exposure. Compliance posture drift + audit readiness (prove you’re monitoring and responding). 2) Palo Alto Prisma Cloud CWPP (Preview) What comes in: CWPP alerts via Prisma Cloud API (Compute/runtime side). Implementation detail: Built on Codeless Connector Platform (CCP). Best for: Runtime detections (host/container/serverless security alerts) “Exploit succeeded” signals that you need to correlate with posture and exposure. 3) Palo Alto Cortex Xpanse CCF What comes in: Alerts logs fetched from the Cortex Xpanse API, ingested using Microsoft Sentinel Codeless Connector Framework (CCF). Important: Supports DCR-based ingestion-time transformations that parse to a custom table for better performance. Best for: External exposure findings and “internet-facing risk” detection Turning exposure into incidents only when the asset is critical / actively targeted. Reference architecture (how the data lands in Sentinel) Here’s the mental model you want for all three: flowchart LR A[Palo Alto Prisma Cloud CSPM] -->|CSPM API: alerts + audit logs| S[Sentinel Data Connector] B[Palo Alto Prisma Cloud CWPP] -->|Prisma API: runtime alerts| S C[Cortex Xpanse] -->|Xpanse API: exposure alerts| S S -->|CCF/CCP + DCR Transform| T[(Custom Tables)] T --> K[KQL Analytics + Hunting] K --> I[Incidents] I -->P[SOAR Playbooks] K --> W[Workbooks / Dashboards] Key design point: Xpanse explicitly emphasizes DCR transformations at ingestion time, use that to normalize fields early so your queries stay fast under load. Deployment patterns (practical, SOC-friendly setup) Step 0 — Decide what goes to “analytics” vs “storage” If you’re using Sentinel’s data lake strategy, posture/exposure data is a perfect candidate for longer retention (trend + audit), while only “high severity” may need real-time analytics. Step 1 — Install solutions from Content Hub Install: Palo Alto Prisma Cloud CSPM Solution Palo Alto Prisma Cloud CWPP (Preview) Palo Alto Cortex Xpanse CCF Step 2 — Credentials & least privilege Create dedicated service accounts / API keys in Palo Alto products with read-only scope for: CSPM alerts + audit CWPP alerts Xpanse alerts/exposures Step 3 — Validate ingestion (don’t skip this) In Sentinel Logs: Locate the custom tables created by each solution (Tables blade). Run a basic sanity query: “All events last 1h” “Top 20 alert types” “Distinct severities” Tip: Save “ingestion smoke tests” as Hunting queries so you can re-run them after upgrades. Step 4 — Turn on included analytics content (then tune) The Prisma Cloud CSPM solution comes with multiple analytics rules, hunting queries, and playbooks out of the box—enable them gradually and tune thresholds before going wide. Detection engineering: high-signal correlation recipes Below are patterns that consistently outperform “single-source alerts.” I’m giving them as KQL templates using placeholder table names because your exact custom table names/columns are workspace-dependent (you’ll see them after install). Recipe 1 — “Internet-exposed + actively probed” (Xpanse + network logs) Goal: Only fire when exposure is real and there’s traffic evidence. let xpanse = <XpanseTable> | where TimeGenerated > ago(24h) | where Severity in ("High","Critical") | project AssetIp=<ip_field>, Finding=<finding_field>, Severity, TimeGenerated; let net = <NetworkFlowTable> | where TimeGenerated > ago(24h) | where Direction == "Inbound" | summarize Hits=count(), SrcIps=make_set(SrcIp, 50) by DstIp; xpanse | join kind=inner (net) on $left.AssetIp == $right.DstIp | where Hits > 50 | project TimeGenerated, Severity, Finding, AssetIp, Hits, SrcIps Why it works: Xpanse gives you exposure. Flow/WAF/Firewall gives you intent. Recipe 2 — “Misconfiguration that creates a breach path” (CSPM + identity or cloud activity) Goal: Prioritize posture findings that coincide with suspicious access or admin changes. let posture = <PrismaCSPMTable> | where TimeGenerated > ago(7d) | where PolicySeverity in ("High","Critical") | where FindingType has_any ("Public", "OverPermissive", "NoMFA", "EncryptionDisabled") | project ResourceId=<resource_id>, Finding=<finding>, PolicySeverity, FirstSeen=TimeGenerated; let activity = <CloudActivityTable> | where TimeGenerated > ago(7d) | where OperationName has_any ("RoleAssignmentWrite","SetIamPolicy","AddMember","CreateAccessKey") | project ResourceId=<resource_id>, Actor=<caller>, OperationName, TimeGenerated; posture | join kind=inner (activity) on ResourceId | project PolicySeverity, Finding, OperationName, Actor, FirstSeen, TimeGenerated | order by PolicySeverity desc, TimeGenerated desc Recipe 3 — “Runtime alert on a workload that was already high-risk” (CWPP + CSPM) Goal: Raise severity when runtime alerts occur on assets with known posture debt. let risky_assets = <PrismaCSPMTable> | where TimeGenerated > ago(30d) | where PolicySeverity in ("High","Critical") | summarize RiskyFindings=count() by AssetId=<asset_id>; <CWPPTable> | where TimeGenerated > ago(24h) | project AssetId=<asset_id>, AlertName=<alert>, Severity=<severity>, TimeGenerated, Details=<details> | join kind=leftouter (risky_assets) on AssetId | extend RiskScore = coalesce(RiskyFindings,0) | order by Severity desc, RiskScore desc, TimeGenerated desc SOC outcome: same runtime alert, different priority depending on posture risk. Operational (in real life) 1) Normalize severities early If Xpanse is using DCR transforms (it is), normalize severity to a consistent enum (“Informational/Low/Medium/High/Critical”) to simplify analytics. 2) Deduplicate exposure findings Attack surface tools can generate repeated findings. Use a dedup function (hash of asset + finding type + port/service) and alert only on “new or changed exposure.” 3) Don’t incident-everything Treat CSPM findings as: Incidents only when: critical + reachable + targeted OR tied to privileged activity Tickets when: high risk but not active Backlog when: medium/low with compensating controls 4) Make SOAR “safe by default” Automations should prefer reversible actions: Block IP (temporary) Add to watchlist Notify owners Open ticket with evidence bundle …and only escalate to destructive actions after confidence thresholds.Ingesting Google Cloud Logs into Microsoft Sentinel: Native vs. Custom Architectures
Overview of GCP Log Types and SOC Value Modern Security Operations Centers (SOCs) require visibility into key Google Cloud Platform logs to detect threats and suspicious activities. The main log types include: GCP Audit Logs – These encompass Admin Activity, Data Access, and Access Transparency logs for GCP services. They record every administrative action (resource creation, modification, IAM changes, etc.) and access to sensitive data, providing a trail of who did what and when in the cloud. In a SOC context, audit logs help identify unauthorized changes or anomalous admin behavior (e.g. an attacker creating a new service account or disabling logging). They are essential for compliance and forensics, as they detail changes to configurations and access patterns across GCP resources. VPC Flow Logs – These logs capture network traffic flow information at the Virtual Private Cloud (VPC) level. Each entry typically includes source/destination IPs, ports, protocol, bytes, and an allow/deny action. In a SOC, VPC flow logs are invaluable for network threat detection: they allow analysts to monitor access patterns, detect port scanning, identify unusual internal traffic, and profile ingress/egress traffic for anomalies. For example, a surge in outbound traffic to an unknown IP or lateral movement between VMs can be spotted via flow logs. They also aid in investigating data exfiltration and verifying network policy enforcement. Cloud DNS Logs – Google Cloud DNS query logs record DNS requests/responses from resources, and DNS audit logs record changes to DNS configurations. DNS query logs are extremely useful in threat hunting because they can reveal systems resolving malicious domain names (C2 servers, phishing sites, DGA domains) or performing unusual lookups. Many malware campaigns rely on DNS; having these logs in Sentinel enables detection of known bad domains and anomalous DNS traffic patterns. DNS audit logs, on the other hand, track modifications to DNS records (e.g. newly added subdomains or changes in IP mappings), which can indicate misconfigurations or potential domain hijacking attempts. Together, these GCP logs provide comprehensive coverage: audit logs tell what actions were taken in the cloud, while VPC and DNS logs tell what network activities are happening. Ingesting all three into Sentinel gives a cloud security architect visibility to detect unauthorized access, network intrusions, and malware communication in a GCP environment. Native Microsoft Sentinel GCP Connector: Architecture & Setup Microsoft Sentinel offers native data connectors to ingest Google Cloud logs, leveraging Google’s Pub/Sub messaging for scalable, secure integration. The native solution is built on Sentinel’s Codeless Connector Framework (CCF) and uses a pull-based architecture: GCP exports logs to Pub/Sub, and Sentinel’s connector pulls from Pub/Sub into Azure. This approach avoids custom code and uses cloud-native services on both sides. Supported GCP Log Connectors: Out of the box, Sentinel provides connectors for: GCP Audit Logs – Ingests the Cloud Audit Logs (admin activity, data access, transparency). GCP Security Command Center (SCC) – Ingests security findings from Google SCC for threat and vulnerability management. GCP VPC Flow Logs – (Recently added) Ingests VPC network flow logs. GCP Cloud DNS Logs – (Recently added) Ingests Cloud DNS query logs and DNS audit logs. Others – Additional connectors exist for specific GCP services (Cloud Load Balancer logs, Cloud CDN, Cloud IDS, GKE, IAM activity, etc.) via CCF, expanding the coverage of GCP telemetry in Sentinel. Each connector typically writes to its own Log Analytics table (e.g. GCPAuditLogs, GCPVPCFlow, GCPDNS, etc.) and comes with built-in KQL parsers. Architecture & Authentication: The native connector uses Google Pub/Sub as the pipeline for log delivery. On the Google side, you will set up a Pub/Sub Topic that receives the logs (via Cloud Logging exports), and Sentinel will subscribe to that topic. Authentication is handled through Workload Identity Federation (WIF) using OpenID Connect: instead of managing static credentials, you establish a trust between Azure AD and GCP so that Sentinel can impersonate a GCP service account. The high-level architecture is: GCP Cloud Logging (logs from services) → Log Router (export sink) → Pub/Sub Topic → (Secure pull over OIDC) → Azure Sentinel Data Connector → Log Analytics Workspace. This ensures a secure, keyless integration. The Azure side (Sentinel) authenticates as a Google service account via OIDC tokens issued by Azure AD, which GCP trusts through the Workload Identity Provider. Below are the detailed setup steps: GCP Setup (Publishing Logs to Pub/Sub) Enable Required APIs: Ensure the GCP project hosting the logs has the IAM API and Cloud Resource Manager API enabled (needed for creating identity pools and roles). You’ll also need owner/editor access on the project to create the resources below. Create a Workload Identity Pool & Provider: In Google Cloud IAM, create a new Workload Identity Pool (e.g. named “Azure-Sentinel-Pool”) and then a Workload Identity Provider within that pool that trusts your Azure AD tenant. Google provides a template for Azure AD OIDC trust – you’ll supply your Azure tenant ID and the audience and issuer URIs that Azure uses. For Azure Commercial, the issuer is typically https://sts.windows.net/<TenantID>/ and audience api://<some-guid> as documented. (Microsoft’s documentation or Terraform scripts provide these values for the Sentinel connector.) Create a Service Account for Sentinel: Still in GCP, create a dedicated service account (e.g. email address removed for privacy reasons). This account will be what Sentinel “impersonates” via the WIF trust. Grant this service account two key roles: Pub/Sub Subscriber on the Pub/Sub Subscription that will be created (allows pulling messages). You can grant roles/pubsub.subscriber at the project level or on the specific subscription. Workload Identity User on the Workload Identity Pool. In the pool’s permissions, add a principal of the form principalSet://iam.googleapis.com/projects/<WIF_project_number>/locations/global/workloadIdentityPools/<Pool_ID>/* and grant it the role roles/iam.workloadIdentityUser on your service account. This allows the Azure AD identity to impersonate the GCP service account. Note: GCP best practice is often to keep the identity pool in a centralized project and service accounts in separate projects, but as of late 2023 the Sentinel connector UI expected them in one project (a limitation under review). It’s simplest to create the WIF pool/provider and the service account within the same GCP project to avoid connectivity issues (unless documentation confirms support for cross-project). Create a Pub/Sub Topic and Subscription: Open the GCP Pub/Sub service and create a Topic (for example, projects/yourproject/topics/sentinel-logs). It’s convenient to dedicate one topic per log type or use case (e.g. one for audit logs). As you create the topic, you can add a Subscription to it in Pull mode (since Sentinel will pull messages). Use a default subscription with an appropriate name (e.g. sentinel-audit-sub). You can leave the default settings (ack deadline, retention) as is, or extend retention if you want messages to persist longer in case of downtime (default is 7 days). Create a Logging Export (Sink): In GCP Cloud Logging, set up a Log Sink to route the desired logs into the Pub/Sub topic. Go to Logging > Logs Router and create a sink: Give it a descriptive name (e.g. audit-logs-to-sentinel). Choose Cloud Pub/Sub as the Destination and select the topic you created (or use the format pubsub.googleapis.com/projects/yourproject/topics/sentinel-logs). Scope and filters: Decide which logs to include. For Audit Logs, you might include ALL audit logs in the project (the sink can be set to include admin activity, data access, etc., by default for the whole project or even entire organization if created at org level). For other log types like VPC Flow Logs or DNS, you’d set an inclusion filter for those specific log names (e.g. logName:"compute.googleapis.com/vpc_flows" to capture VPC Flow Logs). You can also create organization-level sinks to aggregate logs from all projects. Permissions: When creating a sink, GCP will ask to grant the sink service account publish rights to the Pub/Sub topic. Accept this so logs can flow. Once the sink is created, verify logs are flowing: in Pub/Sub > Subscriptions, you can “Pull” messages manually to see if any logs appear. Generating a test event (e.g., create a VM to produce an audit log, or make a DNS query) can help confirm. At this point, GCP is set up to export logs. All requisite GCP resources (IAM federation, service account, topic/subscription, sink) are ready. Google also provides Terraform scripts (and Microsoft supplies Terraform templates in their GitHub) to automate these steps. Using Terraform, you can stand up the IAM and Pub/Sub configuration quickly if comfortable with code. Azure Sentinel Setup (Connecting the GCP Connector) With GCP publishing logs to Pub/Sub, configure Sentinel to start pulling them: Install the GCP Solution: In the Azure portal, navigate to your Sentinel workspace. Under Content Hub (or Data Connectors), find Google Cloud Platform Audit Logs (for example) and click Install. This deploys any needed artifacts (the connector definition, parser, etc.). Repeat for other GCP solutions (like GCP VPC Flow Logs or GCP DNS) as needed. Open Data Connector Configuration: After installation, go to Data Connectors in Sentinel, search for “GCP Pub/Sub Audit Logs” (or the relevant connector), and select it. Click Open connector page. In the connector page, click + Add new (or Add new collector) to configure a new connection instance. Enter GCP Parameters: A pane will prompt for details to connect: you need to supply the Project ID (of the GCP project where the Pub/Sub lives), the Project Number, the Topic and Subscription name, and the Service Account Email you created. You’ll also enter the Workload Identity Provider ID (the identifier of the WIF provider, usually in format projects/<proj>/locations/global/workloadIdentityPools/<pool>/providers/<provider>). All these values correspond to the GCP resources set up earlier – the UI screenshot in docs shows sample placeholders. Make sure there are no typos (a common error is mixing up project ID (name) with project number, or using the wrong Tenant ID). Data Collection Rule (DCR): The connector may also ask for a Data Collection Rule (DCR) and DCE (Data Collection Endpoint) names. Newer connectors based on CCF use the Log Ingestion API, so behind the scenes a DCR is used. If required, provide a name (the docs often suggest prefixing with “Microsoft-Sentinel-” e.g., Microsoft-Sentinel-GCPAuditLogs-DCR). The system will create the DCR and a DCE for you if not already created. (If you installed via Content Hub, this is often automated – just ensure the names follow any expected pattern.) Connect: Click Connect. Sentinel will attempt to use the provided info to establish connectivity. It performs checks like verifying the subscription exists and that the service account can authenticate. If everything is set up properly, the connector will connect and start streaming data. In case of an error, you’ll receive a detailed message. For example, an error about WIF Pool ID not found or subscription not found indicates an issue in the provided IDs or permissions. Double-check those values if so. Validation: After ~15-30 minutes, verify that logs are arriving. You can run a Log Analytics query on the new table, for example: GCPAuditLogs | take 5 (for audit logs) or GCPVPCFlow | take 5 for flow logs. You should see records if ingestion succeeded. Sentinel also provides a “Data connector health” feature – enable it to get alerts or status on data latency and volume for this connector. Data Flow and Ingestion: Once connected, the system works continuously and serverlessly: GCP Log Router pushes new log entries to Pub/Sub as they occur. The Sentinel connector (running in Azure’s cloud) polls the Pub/Sub subscription. It uses the service account credentials (via OIDC token) to call the Pub/Sub API and pull messages in batches. This happens at a defined interval (typically very frequently, e.g. every few seconds). Each message (which contains a log entry in JSON) is then ingested into Log Analytics. The CCF connector uses the Log Ingestion API on the backend, mapping the JSON fields to the appropriate table schema. The logs appear in the respective table (with columns for each JSON field or a dynamic JSON column, depending on the connector design). Sentinel’s built-in parser or Normalized Schemas (ASIM) can be used to query these logs in a friendly way. For instance, the Audit Logs solution includes KQL functions to parse out common fields like user, method, status, etc., from the raw JSON. This native pipeline is fully managed – you don’t have to run any servers or code. The use of Pub/Sub and OIDC makes it scalable and secure by design. Design Considerations & Best Practices for the Native Connector: Scalability & Performance: The native connector approach is designed for high scale. Pub/Sub itself can handle very large log volumes with low latency. The Sentinel CCF connectors use a SaaS, auto-scaling model – no fixed infrastructure means they will scale out as needed to ingest bursts of data. This is a significant advantage over custom scripts or function apps which might need manual scaling. In testing, the native connector can reliably ingest millions of log events per day. If you anticipate extremely high volumes (e.g. VPC flow logs from hundreds of VMs), monitor the connector’s performance but it should scale automatically. Reliability: By leveraging Pub/Sub’s at-least-once delivery, the integration is robust. Even if Azure or the connector has a transient outage, log messages will buffer in Pub/Sub. Once the connector resumes, it will catch up on the backlog. Ensure the subscription’s message retention is adequate (the default 7 days is usually fine). The connector acknowledges messages only after they’re ingested into Log Analytics, which prevents data loss on failures. This reliability is achieved without custom code – reducing the chance of bugs. Still, it’s good practice to use Sentinel’s connector health metrics to catch any issues (e.g., if the connector hasn’t pulled data in X minutes, indicating a problem). Security: The elimination of persistent credentials is a best practice. By using Workload Identity Federation, the Azure connector obtains short-lived tokens to act as the GCP service account. There is no need to store a GCP service account key file, which could be a leak risk. Ensure that the service account has the minimal roles needed. Typically, it does not need broad viewer roles on all GCP resources – it just needs Pub/Sub subscription access (and logging viewer only if you choose to restrict log export by IAM – usually not necessary since the logs are already exported via the sink). Keep the Azure AD application’s access limited too: the Azure AD app (which underpins the Sentinel connector) only needs to access the Sentinel workspace and doesn’t need rights in GCP – the trust is handled by the WIF provider. Filtering and Log Volume Management: A common best practice is to filter GCP logs at the sink to avoid ingesting superfluous data. For instance, if only certain audit log categories are of interest (e.g., Admin Activity and security-related Data Access), you could exclude noisy Data Access logs like storage object reads. For VPC Flow Logs, you might filter on specific subnetworks or even specific metadata (though typically you’d ingest all flows and use Sentinel for filtering). Google’s sink filters allow you to use boolean expressions on log fields. The community recommendation for Firewall or VPC logs, for example, is to set a filter so that only those logs go into that subscription. This reduces cost and noise in Sentinel. Plan your log sinks carefully: you may create multiple sinks if you want to separate log types (one sink to Pub/Sub for audit logs, another sink (with its own topic) for flow logs, etc.). The Sentinel connectors are each tied to one subscription and one table, so separating by log type can help manage parsing and access. Coverage Gaps: Check what the native connectors support as of the current date. Microsoft has been rapidly adding GCP connectors (VPC Flow Logs and DNS logs were in Preview in mid-2025 and are likely GA by now). If a needed log type is not supported (for example, if you have a custom application writing logs to Google Cloud Logging), you might consider the custom ingestion approach (see next section). For most standard infrastructure logs, the native route is available and preferable. Monitoring and Troubleshooting: Familiarize yourself with the connector’s status in Azure. In the Sentinel UI, each configured GCP connector instance will show a status (Connected/Warning/Error) and possibly last received timestamp. If there’s an issue, gather details from error messages there. On GCP, monitor the Pub/Sub subscription: pubsub subscriptions list --filter="name:sentinel-audit-sub" can show if there’s a growing backlog (unacked message count). A healthy system should have near-zero backlog with steady consumption. If backlog is growing, it means the connector isn’t keeping up or isn’t pulling – check Azure side for throttling or errors. Multi-project or Org-wide ingestion: If your organization has many GCP projects, you have options. You could deploy a connector per project, or use an organization-level log sink in GCP to funnel logs from all projects into a single Pub/Sub. The Sentinel connector can pull organization-wide if the service account has rights (the Terraform script allows an org sink by providing an organization-id). This centralizes management but be mindful of very large volumes. Also, ensure the service account has visibility on those logs (usually not an issue if they’re exported; the sink’s own service account handles the export). In summary, the native GCP connector provides a straightforward and robust way to get Google Cloud logs into Sentinel. It’s the recommended approach for supported log types due to its minimal maintenance and tight integration. Custom Ingestion Architecture (Pub/Sub to Azure Event Hub, etc.) In cases where the built-in connector doesn’t meet requirements – e.g., unsupported log types, custom formats, or corporate policy to use an intermediary – you can design a custom ingestion pipeline. The goal of custom architectures is the same (move logs from GCP to Sentinel) but you can incorporate additional processing or routing. One reference pattern is: GCP Pub/Sub → Azure Event Hub → Sentinel, which we’ll use as an example among other alternatives. GCP Export (Source): This part remains the same as the native setup – you create log sinks in GCP to continuously export logs to Pub/Sub topics. You can reuse what you’ve set up or create new, dedicated Pub/Sub topics for the custom pipeline. For instance, you might have a sink for Cloud DNS query logs if the native connector wasn’t used, sending those logs to a topic. Ensure you also create subscriptions on those topics for your custom pipeline to pull from. If you plan to use a GCP-based function to forward data, a Push subscription could be used instead (which can directly call an HTTP endpoint), but a Pull model is more common for custom solutions. Bridge / Transfer Component: This is the core of the custom pipeline – a piece of code that reads from Pub/Sub and sends data to Azure. Several implementation options: Google Cloud Function or Cloud Run (in GCP): You can deploy a Cloud Function that triggers on new Pub/Sub messages (using Google’s EventArc or a Pub/Sub trigger). This function will execute with the message as input. Inside the function, you would parse the Pub/Sub message and then forward it to Azure. This approach keeps the “pull” logic on the GCP side – effectively GCP pushes to Azure. For example, a Cloud Function (Python) could be subscribed to the sentinel-logs topic; each time a log message arrives, the function runs, authenticates to Azure, and calls the ingestion API. Cloud Functions can scale out automatically based on the message volume. Custom Puller in Azure (Function App or Container): Instead of running the bridging code in GCP, you can run it in Azure. For instance, an Azure Function with a timer trigger (running every minute) or an infinite-loop container in Azure Kubernetes Service could use Google’s Pub/Sub client library to pull messages from GCP. You would provide it the service account credentials (likely a JSON key) to authenticate to the Pub/Sub pull API. After pulling a batch of messages, it would send them to the Log Analytics workspace. This approach centralizes everything in Azure but requires managing GCP credentials securely in Azure. Using Google Cloud Dataflow (Apache Beam): For a heavy-duty streaming solution, you could write an Apache Beam pipeline that reads from Pub/Sub and writes to an HTTP endpoint (Azure). Google Dataflow runs Beam pipelines in a fully managed way and can handle very large scale with exactly-once processing. However, this is a complex approach unless you already use Beam – it’s likely overkill for most cases and involves significant development. No matter which method, the bridge component must handle reading, transforming, and forwarding logs efficiently. Destination in Azure: There are two primary ways to ingest the data into Sentinel: Azure Log Ingestion API (via DCR) – This is the modern method (introduced in 2022) to send custom data to Log Analytics. You’ll create a Data Collection Endpoint (DCE) in Azure and a Data Collection Rule (DCR) that defines how incoming data is routed to a Log Analytics table. For example, you might create a custom table GCP_Custom_Logs_CL for your logs. Your bridge component will call the Log Ingestion REST API endpoint (which is a URL associated with the DCE) and include a shared access signature or Azure AD token for auth. The payload will be the log records (in JSON) and the DCR rule ID to apply. The DCR can also perform transformations if needed (e.g., mappings of fields). This API call will insert the data into Log Analytics in real-time. This approach is quite direct and is the recommended custom ingestion method (it replaces the older HTTP Data Collector API). Azure Event Hub + Sentinel Connector – In this approach, instead of pushing directly into Log Analytics, you use an Event Hub as an intermediate buffer in Azure. Your GCP bridge will act as a producer, sending each log message to an Event Hub (over AMQP or using Azure’s SDK). Then, you need something to get data from Event Hub into Sentinel. There are a couple of options: Historically, Sentinel provided an Event Hub data connector (often used for Azure Activity logs or custom CEF logs). This connector can pull events from an Event Hub and write to Log Analytics. However, it typically expects the events to be in a specific format (like CEF or JSON with a known structure). If your logs are raw JSON, you might need to wrap them or use a compatible format. This method is somewhat less flexible unless you tailor your output to what Sentinel expects. Alternatively (and more flexibly), you can write a small Azure Function that triggers on the Event Hub (using Event Hub trigger binding). When a message arrives, the function takes it and calls the Log Ingestion API (similar to method (a) above) to put it into Log Analytics. Essentially, this just decouples the pulling from GCP (done by the first function) and the pushing to Sentinel (done by the second function). This two-stage design might be useful if you want to do more complex buffering or retries, but it does introduce more components. Using an Event Hub in the pipeline can be beneficial if you want a cloud-neutral queue between GCP and Azure (maybe your organization already consolidates logs in an Event Hub or Kafka). It also allows reusing any existing tools that read off Event Hubs (for example, maybe feeding the same data to another system in parallel to Sentinel). This pattern – Cloud Logging → Pub/Sub → Event Hub → Log Analytics – has been observed in real-world multi-cloud deployments, essentially treating Pub/Sub + Event Hub as a bridging message bus between clouds. Data Transformation: With a custom pipeline, you have full control (and responsibility) for any data transformations needed. Key considerations: Message Decoding: GCP Pub/Sub messages contain the log entry in the data field, which is a base64-encoded string of a JSON object. Your code must decode that (it’s a one-liner in most languages) to get the raw JSON log. After decoding, you’ll have a JSON structure identical to what you’d see in Cloud Logging. For example, an audit log entry JSON has fields like protoPayload, resourceName, etc. Schema Mapping: Decide how to map the JSON to your Log Analytics table. You could ingest the entire JSON as a single column (and later parse in KQL), but it’s often better to map important fields. For instance, for VPC Flow Logs, you might extract src_ip, dest_ip, src_port, dest_port, bytes_sent, action and map each to a column in a custom table. This requires that you create the custom table with those columns and configure the DCR’s transformation schema accordingly. If using the Log Ingestion API, the DCR can transform the incoming JSON to the table schema. If using the Data Collector API (legacy, not recommended now), your code would need to format records as the exact JSON that Log Analytics expects. Enrichment (optional): In a custom pipeline, you could enrich the logs before sending to Sentinel. For example, performing IP geolocation on VPC flow logs, or tagging DNS logs with threat intel (if a domain is known malicious) – so that the augmented information is stored in Sentinel. Be cautious: enrichment adds processing time and potential failure points. If it’s light (like a dictionary lookup), it might be fine; if heavy, consider doing it after ingestion using Sentinel analytics instead. Filtering: Another advantage of custom ingestion is that you can filter events at the bridge. You might decide to drop certain events entirely (to save cost or noise). For example, if DNS query logs are too verbose, you might only forward queries for certain domains or exclude known benign domains. Or for audit logs, you might exclude read-only operations. This gives flexibility beyond what the GCP sink filter can do, since you have the full event content to decide. The trade-off is complexity – every filter you implement must be maintained/justified. Batching: The Log Ingestion API allows sending multiple records in one call. It’s more efficient to batch a bunch of log events (say 100 at a time) into one API request rather than call per event. Your function can accumulate a short batch (with some timeout or max size) and send together. This improves throughput and lowers overhead. Ensure the payload stays within API limits (~1 MB per post, and 30,000 events per post for Log Ingestion API). Pub/Sub and Event Hub also have batch capabilities – you may receive multiple messages in one invocation or read them in a loop. Design your code to handle variable batch sizes. Authentication & Permissions (Custom Pipeline): You will effectively need to handle two authentications: GCP → Bridge, and Bridge → Azure: GCP to Bridge: If using a GCP Cloud Function triggered by Pub/Sub, GCP handles the auth for pulling the message (the function is simply invoked with the data). If pulling from Azure, you’ll need GCP credentials. The most secure way is to use a service account key with minimal permissions (just Pub/Sub subscriber on the subscription). Store this key securely (Azure Key Vault or as an App Setting in the Azure Function, possibly encrypted). The code uses this key (a JSON file or key string) to initialize the Pub/Sub client. Google’s libraries support reading the key from an environment variable. Alternatively, you could explore using the same Workload Identity Federation concept in reverse (Azure to GCP), but that’s non-trivial to set up manually for custom code. A service account key is straightforward but do rotate it periodically. On GCP’s side, you might also restrict the service account so it cannot access anything except Pub/Sub. Bridge to Azure: To call the Log Ingestion API, you need an Azure AD App Registration (client ID/secret) with permissions or a SAS token for the DCR. The modern approach: create an AAD app, grant it the role Monitoring Data Contributor on your Sentinel workspace or explicitly grant the DCR permissions (Log Ingestion Data Contributor). Then your code can use the app’s client ID and secret to get a token and call the API. This is a secure, managed way. Alternatively, the DCR can be configured with a shared access signature (SAS) that you generate in Azure – your code could use that SAS token in the API URL (so that no interactive auth is needed). The older Data Collector API used the workspace ID and a primary key for auth (HMAC SHA-256 header) – some existing solutions still use that, but since that API is being deprecated, it’s better to use the new method. In summary: ensure the Azure credentials are stored safely (Key Vault or GCP Secret Manager if function is in GCP) and that you follow principle of least privilege (only allow ingest, no read of other data). End-to-End Data Flow Example: To make this concrete, consider an example where we ingest Firewall/VPC logs using a custom pipeline (this mirrors a solution published by Microsoft for when these logs weren’t yet natively supported): A GCP Log Sink filters for VPC Firewall logs (the logs generated by GCP firewall rules, which are part of VPC flow logging) and exports them to a Pub/Sub topic. An Azure Function (in PowerShell, as in the example, or any language) runs on a timer. Every minute, it pulls all messages from the Pub/Sub subscription (using the Google APIs). The function authenticates with a stored service account key to do this. It then decodes each message’s JSON. The function constructs an output in the required format for Sentinel’s Log Ingestion API. In this case, they created a custom Log Analytics table (say GCPFirewall_CL) with columns matching the log fields (source IP, dest IP, action, etc.). The function maps each JSON field to a column. For instance, json.payload.sourceIp -> src_ip column. It then calls the Log Ingestion REST API to send a batch of log records. The call is authorized with an Azure AD app’s client ID/secret which the function has in its config. Upon successfully POSTing the data, the function sends an acknowledgment back to Pub/Sub for those messages (or, if using the Pub/Sub client in pull mode, it acks as it pulls). This removal is important to ensure the messages don’t get re-delivered. If the send to Azure fails for some reason, the function can choose not to ack, so that the message remains in Pub/Sub and will be retried on the next run (ensuring reliability). The logs show up in Sentinel under the custom table, and can now be used in queries and analytics just like any other log. The entire process from log generation in GCP to log ingestion in Sentinel can be only a few seconds of latency in this design, effectively near-real-time. Tooling & Infrastructure: When implementing the above, some recommended tools: Use official SDKs where possible. For example, Google Cloud has a Pub/Sub client library for Python, Node.js, C#, etc., which simplifies pulling messages. Azure has an SDK for the Monitor Ingestion API (or you can call the REST endpoints directly with an HTTP client). This saves time versus manually crafting HTTP calls and auth. Leverage Terraform or IaC for repeatability. You can automate creation of Azure resources (Function App, Event Hub, etc.) and even the GCP setup. For instance, the community SCC->Sentinel example provides Terraform scripts. This makes it easier to deploy the pipeline in dev/test and prod consistently. Logging and monitoring: implement robust logging in your function code. In GCP Cloud Functions, use Cloud Logging to record errors (so you can see if something fails). In Azure Functions, use Application Insights to track failures or performance metrics. Set up alerts if the function fails repeatedly or if an expected log volume drops (which could indicate a broken pipeline). Essentially, treat your custom pipeline as you would any production integration – monitor its health continuously. Example Use-Case – Ingesting All Custom GCP Logs: One key advantage of a custom approach is flexibility. Imagine you have a custom application writing logs to Google Cloud Logging (Stackdriver) that has no out-of-the-box Sentinel connector. You can still get those logs into Sentinel. As one cloud architect noted, they built a fully custom pipeline with GCP Log Sink -> Pub/Sub -> Cloud Function -> Sentinel, specifically to ingest arbitrary GCP logs beyond the built-in connectors. This unlocked visibility into application-specific events that would otherwise be siloed. While doing this, they followed many of the steps above, demonstrating that any log that can enter Pub/Sub can ultimately land in Sentinel. This extensibility is a major benefit of a custom solution – you’re not limited by what Microsoft or Google have pre-integrated. In summary, the custom ingestion route requires more effort up front, but it grants complete control. You can tune what you collect, transform data to your needs, and integrate logs that might not be natively supported. Organizations often resort to this if they have very specific needs or if they started building ingestion pipelines before native connectors were available. Many will start with custom for something like DNS logs and later switch to a native connector once available. A hybrid approach is also possible (using native connector for audit logs, but custom for a niche log source). Comparison of Native vs. Custom Ingestion Methods Both native and custom approaches will get your GCP logs into Microsoft Sentinel, but they differ in complexity and capabilities. The table below summarizes the trade-offs to help choose the right approach: Aspect Native GCP Connector (Sentinel Pub/Sub Integration) Custom Ingestion Pipeline (DIY via Event Hubs or API) Ease of Setup Low-Code Setup: Requires configuration in GCP and Azure, but no custom code. You use provided Terraform scripts and a UI wizard. In a few hours you can enable the connector if prerequisites (IAM, Pub/Sub) are met. Microsoft’s documentation guides the process step by step. High-Code Setup: Requires designing and writing integration code (function or app) and configuring cloud services (Function Apps, Event Hub, etc.). More moving parts mean a longer setup time – possibly days or weeks to develop and thoroughly test. Suitable if your team has cloud developers or if requirements demand it. Log Type Coverage Supported Logs: Out-of-the-box support for standard GCP logs (audit, SCC findings, VPC flow, DNS, etc.). However, it’s limited to those data types Microsoft has released connectors for. (As of 2025, many GCP services are covered, but not necessarily all Google products.) If a connector exists, it will reliably ingest that log type. Any Log Source: Virtually unlimited – you can ingest any log from GCP, including custom application logs or niche services, as long as you can export it to Pub/Sub. You define the pipeline for each new log source. This is ideal for custom logs beyond built-ins. The trade-off is you must build parsing/handling for each log format yourself. Development & Maintenance Minimal Maintenance: After initial setup, the connector runs as a service. No custom code to maintain; Microsoft handles updates/improvements. You might need to update configuration if GCP projects or requirements change, but generally it’s “configure and monitor.” Support is available from Microsoft for connector issues. Ongoing Maintenance: You own the code. Updates to log schemas, API changes, or cloud platform changes might require code modifications. You need to monitor the custom pipeline, handle exceptions, and possibly update credentials regularly. This approach is closer to software maintenance – expect to allocate effort for bug fixes or improvements over time. Scalability Cloud-Scale (Managed): The connector uses Azure’s cloud infrastructure which auto-scales. High volumes are handled by scaling out processing nodes behind the scenes. GCP Pub/Sub will buffer and deliver messages at whatever rate the connector can pull, and the connector is optimized for throughput. There’s effectively no hard limit exposed to you (aside from Log Analytics ingestion rate limits, which are very high). Custom Scaling Required: Scalability depends on your implementation. Cloud Functions and Event Hubs can scale, but you must configure them (e.g., set concurrency, ensure enough throughput units on Event Hub). If logs increase tenfold, you may need to tweak settings or upgrade plans. There’s more possibility of bottlenecks (e.g., a single-threaded function might lag). Designing for scale (parallelism, batching, multi-partition processing) is your responsibility. Reliability & Resilience Reliable by Design: Built on proven Google Pub/Sub durability and Azure’s reliable ingestion pipeline. The connector handles retries and acknowledgements. If issues occur, Microsoft likely addresses them in updates. Also, you get built-in monitoring in Sentinel for connector health. Reliability Varies: Requires implementing your own retry and error-handling logic. A well-built custom pipeline can be very reliable (e.g., using Pub/Sub’s ack/retry and durable Event Hub storage), but mistakes in code could drop logs or duplicate them. You need to test failure scenarios (network blips, API timeouts, etc.). Additionally, you must implement your own health checks/alerts to know if something breaks. Flexibility & Transformation Standardized Ingestion: Limited flexibility – it ingests logs in their native structure into pre-defined tables. Little opportunity to transform data (beyond what the connector’s mapping does). Essentially “what GCP sends is what you get,” and you rely on Sentinel’s parsing for analysis. All logs of a given type are ingested (you control scope via GCP sink filters, but not the content). Highly Flexible: You can customize everything – which fields to ingest, how to format them, and even augment logs with external data. For example, you could drop benign DNS queries or mask sensitive fields before sending. You can consolidate multiple GCP log types into one table or split one log type into multiple tables if desired. This freedom lets you tailor the data to your environment and use cases. The flip side is complexity: every transformation is custom logic to maintain. Cost Considerations Cost-Efficient Pipeline: There is no charge for the Sentinel connector itself (it’s part of the service). Costs on GCP: Pub/Sub charges are minimal (especially for pulling data) and logging export has no extra cost aside from the egress of the data. On Azure: you pay for data ingestion and storage in Log Analytics as usual. No need to run VMs or functions continuously. Overall, the native route avoids infrastructure costs – you’re mainly paying for the data volume ingested (which is unavoidable either way) and a tiny cost for Pub/Sub (pennies for millions of messages). Additional Costs: On top of Log Analytics ingestion costs, you will incur charges for the components you use. An Azure Function or Cloud Function has execution costs (though modest, they add up with high volume). An Event Hub has hourly charges based on throughput units and retention. Data egress from GCP to Azure will be charged by Google (network egress fees) – this also applies to the native connector, though in that case GCP egress is typically quite small cost. If your pipeline runs 24h, ensure to factor in those platform costs. Custom pipelines can also potentially reduce Log Analytics costs by filtering out data (saving money by not ingesting noise), so there’s a trade-off: spend on processing to save on storage, if needed. Support & Troubleshooting Vendor-Supported: Microsoft supports the connector – if things go wrong, you can open a support case. Documentation covers common setup issues. The connector UI will show error messages (e.g., authentication failures) to guide troubleshooting. Upgrades/improvements are handled by Microsoft (e.g., if GCP API changes, Microsoft will update the connector). Self-Support: You build it, you fix it. Debugging issues might involve checking logs across two clouds. Community forums and documentation can help (e.g., Google’s docs for Pub/Sub, Azure docs for Log Ingestion API). When something breaks, your team must identify whether it’s on the GCP side (sink or Pub/Sub) or Azure side (function error or DCR issue). This requires familiarity with both environments. There’s no single vendor to take responsibility for the end-to-end pipeline since it’s custom. In short, use the native connector whenever possible – it’s easier and reliably maintained. Opt for a custom solution only if you truly need the flexibility or to support logs that the native connectors can’t handle. Some organizations start with custom ingestion out of necessity (before native support exists) and later migrate to native connectors once available, to reduce their maintenance burden. Troubleshooting Common Issues Finally, regardless of method, you may encounter some hurdles. Here are common issues and ways to address them in the context of GCP-to-Sentinel log integration: No data appearing in Sentinel: If you’ve set up a connector and see no logs, first be patient – initial data can take ~10–30 minutes to show up. If nothing appears after that, verify the GCP side: Check the Log Router sink status in GCP (did you set the correct inclusion filters? Are logs actually being generated? You can view logs in Cloud Logging to confirm the events exist). Go to Pub/Sub and use the “Pull” option on the subscription to see if messages are piling up. If you can pull messages manually but Sentinel isn’t getting them, the issue is likely on the Azure side. In Sentinel, ensure the connector shows as Connected. If it’s in an error state, click on it to see details. A common misconfiguration is an incorrect Project Number or Service Account in the connector settings – one typo in those will prevent ingestion. Update the parameters if needed and reconnect. Authentication or Connectivity errors (native connector): These show up as errors like “Workload Identity Pool ID not found” or “Subscription does not exist” in the connector page. This usually means the values entered in the connector are mismatched: Double-check the Workload Identity Provider ID. It must exactly match the one in GCP (including correct project number). If you created the WIF pool in a different project than the Pub/Sub, remember the connector (until recently) expected them in one project. Ensure you used the correct project ID/number for all fields. Verify the service account email is correct and that you granted the Workload Identity User role on it. If not, the Azure identity cannot assume the service account. Check that the subscription name is correct and that the service account has roles/pubsub.subscriber on it. If you forgot to add that role, Azure will be denied access to Pub/Sub. Ensure the Azure AD app (which is automatically used by Sentinel) wasn’t deleted or disabled in your tenant. The Sentinel connector uses a multi-tenant app provided by Microsoft (identified by the audience GUID in the docs), which should be fine unless your org blocked third-party Azure apps. If you have restrictions, you might need to allow Microsoft’s Sentinel multi-cloud connector app. Tip: Try running the Terraform scripts provided by Microsoft if you did things manually and it’s failing. The scripts often can pinpoint what’s missing by setting everything up for you. Partial data or specific logs missing: If some expected events are not showing up: Revisit your sink filter in GCP. Perhaps the filter is too narrow. For example, for DNS logs, you might need to include both _Default logs and DNS-specific log IDs. Or for audit logs, remember that Data Access logs for certain services might be excluded by default (you have to enable Data Access audit logs in GCP for some services). If those aren’t enabled in GCP, they won’t be exported at all. If using the SCC connector, ensure you enabled continuous export of findings in SCC to Pub/Sub – those findings won’t flow unless explicitly configured. Check Sentinel’s table for any clues – sometimes logs might arrive under a slightly different table or format. E.g., if the connector was set up incorrectly initially, it might have sent data to a custom table with a suffix. Use Log Analytics query across all tables (or search by a specific IP or timestamp) to ensure the data truly isn’t there. Duplicate logs or high event counts (custom ingestion): If your custom pipeline isn’t carefully handling acknowledgments, you might ingest duplicates. For instance, if your function crashes after sending data to Sentinel but before acking Pub/Sub, the message will be retried later – resulting in the same log ingested twice. Over time this could double-count events. Solution: Ensure idempotency or proper ack logic. One way is to include a unique ID with each log (GCP audit logs have an insertId which is unique per log event; VPC flow logs have unique flowID for each flow chunk). You could use that as a de-duplication key on the Sentinel side (e.g., ingest it and deduplicate in queries). Or design the pipeline to mark messages as processed in an external store. However, the simplest is to acknowledge only after successful ingestion and let Pub/Sub handle retries. If you notice duplicates in Sentinel, double-check that your code isn’t calling ack too early or multiple times. Log Ingestion API errors (custom pipeline): When calling the Log Ingestion API, you might encounter HTTP errors: 400 Bad Request – often schema mismatch. This means the JSON you sent doesn’t match the DCR’s expected format. Check the error details; the API usually returns a message indicating which field is wrong. Common issues: sending a string value for a column defined as integer, missing a required column, or having an extra column that’s not in the table. Adjust your transformation or DCR accordingly. 403 Forbidden – authentication failure. Your Azure AD token might be expired or your app doesn’t have rights. Make sure the token is fresh (fetch a new one for each function run, or use a managed identity if supported and authorized). Also verify the app’s role assignments. 429 Too Many Requests / Throttling – you might be sending data too fast. The Log Ingestion API has throughput limits (per second per workspace). If you hit these, implement a backoff/retry and consider batching more. This is rare unless you have a very high log rate. Azure Function timeouts – if using Functions, sometimes the default timeout (e.g., 5 minutes for an HTTP-triggered function) might be hit if processing a large batch. Consider increasing the timeout setting or splitting work into smaller chunks. Connector health alerts: If you enabled the health feature for connectors, you might get alerted that “no logs received from GCP Audit Logs in last X minutes” etc. If this is a false alarm (e.g., simply that there were genuinely no new logs in GCP during that period), you can adjust the alert logic or threshold. But if it’s a real issue, treat it as an incident: check GCP’s Cloud Logging to ensure new events exist (if not, maybe nothing happened – e.g., no admin activity in the last hour). If events do exist in GCP but none in Sentinel, you have a pipeline problem – refer to the earlier troubleshooting steps for auth/connectivity. Updating or Migrating pipelines: Over time, you might replace a custom pipeline with a native connector (or vice versa). Be cautious of duplicate ingestion if both are running simultaneously. For example, if you enable the new GCP DNS connector while your custom DNS log pipeline is still on, you’ll start ingesting DNS logs twice. Plan a cutover: disable one before enabling the other in production. Also, if migrating, note that the data may land in a different table (the native connector might use GCPDNS table whereas your custom went to GCP_DNS_Custom_CL). You may need to adjust your queries and workbooks to unify this. It could be worthwhile to backfill historical data for continuity if needed. By following these practices and monitoring closely, you can ensure a successful integration of GCP logs into Microsoft Sentinel. The end result is a centralized view in Sentinel where your Azure, AWS, on-prem, and now GCP logs all reside – empowering your SOC to run advanced detections and investigations across your multi-cloud environment using a single pane of glass.
XDR advanced hunting region specific endpoints
Hi, I am exploring XDR advanced hunting API to fetch data specific to Microsoft Defender for Endpoint tenants. The official documentation (https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) mentions to switch to Microsoft Graph advanced hunting API. I had below questions related to it: 1. To fetch the region specific(US , China, Global) token and Microsoft Graph service root endpoints(https://learn.microsoft.com/en-us/graph/deployments#app-registration-and-token-service-root-endpoints ) , is the recommended way to fetch the OpenID configuration document (https://learn.microsoft.com/en-us/entra/identity-platform/v2-protocols-oidc#fetch-the-openid-configuration-document) for a tenant ID and based on the response, the region specific SERVICE/TOKEN endpoints could be fetched? Since using it, there is no need to maintain different end points for tenants in different regions. And do we use the global service URL https://login.microsoftonline.com to fetch OpenID config document for a tenantID in any region? 2. As per the documentation, Microsoft Graph Advanced hunting API is not supported in China region (https://learn.microsoft.com/en-us/graph/api/security-security-runhuntingquery?view=graph-rest-1.0&tabs=http). In this case, is it recommended to use Microsoft XDR Advanced hunting APIs(https://learn.microsoft.com/en-us/defender-xdr/api-advanced-hunting) to support all region tenants(China, US, Global)?
Deep Dive into Preview Features in Microsoft Defender Console
Background for Discussion Microsoft Defender XDR (Extended Detection and Response) is evolving rapidly, offering enhanced security capabilities through preview features that can be enabled in the MDE console. These preview features are accessible via: Path: Settings > Microsoft Defender XDR > General > Preview features Under this section, users can opt into three distinct integrations: Microsoft Defender XDR + Microsoft Defender for Identity Microsoft Defender for Endpoint Microsoft Defender for Cloud Apps Each of these options unlocks advanced functionalities that improve threat detection, incident correlation, and response automation across identity, endpoint, and cloud environments. However, enabling these features is optional and may depend on organizational readiness or policy. This raises important questions about: What specific technical capabilities are introduced by each preview feature? Where exactly are these feature parameters are reflected in the MDE console? What happens if an organization chooses not to enable these preview features? Are there alternative ways to access similar functionalities through public preview or general availability?
How to Connect MS Secure Scores to Power Query?
The Microsoft 365 Defender Portal (https://security.microsoft.com/) has a 'Secure Score' page, which contains the following: An overall secure score which is then broken down by Identity, Data, Device, and Application secure scores. I would like to be able to pull these four scores into a Power BI report; however, I have had some difficulty in putting together a solution. This data seems like it could be found in the Microsoft Graph API, but https://learn.microsoft.com/en-us/power-query/connecting-to-graph. I've tried other Defender APIs, but they all seem either outdated or out of scope for what I'm trying to pull. Can anyone advise? Thanks for reading.
