Security teams often struggle to understand the full context of an attack. In many cases, they rely solely on Indicators of Compromise (IoCs) without the broader insights provided by threat intelligence developed on Threat Actors, Attack Patterns, Identities - and the Relationships between each. This lack of context available to enrich their workflows limits their ability to connect the dots, prioritize threats effectively, and respond comprehensively to evolving attacks. To help customers build out a thorough, real-time understanding of threats, we are excited to announce the public preview of new Threat Intelligence (TI) object support in Microsoft Sentinel and in the Unified SOC Platform. In addition to Indicators of Compromise (IoCs), Microsoft Sentinel now supports Threat Actors, Attack Patterns, Identities, and Relationships. This enhancement empowers organizations to take their threat intelligence management to the next level. In this blog, we’ll highlight key scenarios for which your team would use STIX objects, as well as demos showing how to create objects and new relationships and how to use them to hunt threats across your organization Key Scenarios STIX objects are a critical tool for incident responders attempting to understand an attack and threat intelligence analysts seeking more information on critical threats. It is designed to improve interoperability and sharing of threat intelligence across different systems and organizations. Below, we’ve highlighted four ways Unified SOC Platform customers can begin using STIX objects to protect their organization. Ingesting Objects: You can now ingest these objects from various commercial feeds through several methods including STIX TAXII servers, API, files, or manual input. Curating Threat Intelligence: Curate and manage any of the supported Threat Intelligence objects. Creating Relationships: Establish connections between objects to enhance threat detection and response. For example: Connecting Threat Actor to Attack Pattern: The threat actor "APT29" uses the attack pattern "Phishing via Email" to gain initial access. Linking Indicator to Threat Actor: An indicator (malicious domain) is attributed to the threat actor "APT29". Associating Identity (Victim) with Attack Pattern: The organization "Example Corp" is targeted by the attack pattern "Phishing via Email". Hunt and Investigate Threats More Effectively: Match curated TI data against your logs in the unified SOC platform powered by Microsoft Sentinel. Use these insights to detect, investigate, and hunt threats more efficiently, keeping your organization secure. Get Started Today with the new Hunting Model The ability to ingest and manage these new Threat Intelligence objects is now available in public preview. To enable this data in your workspaces for hunting and detection, submit your request here and we will provide further details. Demo and screen shots Demo 1: Hunt and detect threats using STIX objects Scenario: Linking an IOC to a Threat Actor: An indicator (malicious domain) is attributed to the threat actor " Sangria tempest " via the new TI relationship builder. Please note that the Sangria tempest actor object and the IOC are already present in this demo. These objects can be added automatically or created manually. To create new relationship, sign into your Sentinel instance and go to Add new à TI relationship. In the New TI relationship builder, you can select existing TI objects and define how it's related to one or more other TI objects. After defining a TI object’s relationship, click on “Common” to provide metadata for this relationship, such as Description, Tags, and Confidence score: p time, source, and description. Another type of meta data a customer can add to a relationship is the Traffic Light Protocol (TLP). The TLP is a set of designations used to ensure that sensitive information is shared with the appropriate audience. It uses four colors to indicate different levels of sensitivity and the corresponding sharing permissions: TLP:RED: Information is highly sensitive and should not be shared outside of the specific group or meeting where it was originally disclosed. TLP:AMBER: Information can be shared with members of the organization, but not publicly. It is intended to be used within the organization to protect sensitive information. TLP:GREEN: Information can be shared with peers and partner organizations within the community, but not publicly. It is intended for a wider audience within the community. TLP:WHITE: Information can be shared freely and publicly without any restrictions. Once the relationship is created, your newly created relationship can be viewed from the “Relationships” tab. Now, retrieve information about relationships and indicators associated with the threat actor 'Sangria Tempest'. For Microsoft Sentinel customers leveraging the Azure portal experience, you can access this in Log Analytics. For customers who have migrated to the unified SecOps platform in the Defender portal, you can go find this under “Advanced Hunting”. The following KQL query provides you with all TI objects related to “Sangria Tempest.” You can use this query for any threat actor name. let THREAT_ACTOR_NAME = 'Sangria Tempest'; let ThreatIntelObjectsPlus = (ThreatIntelObjects | union (ThreatIntelIndicators | extend StixType = 'indicator') | extend tlId = tostring(Data.id) | extend StixTypes = StixType | extend Pattern = case(StixType == "indicator", Data.pattern, StixType == "attack-pattern", Data.name, "Unkown") | extend feedSource = base64_decode_tostring(tostring(split(Id, '---')[0])) | summarize arg_max(TimeGenerated, *) by Id | where IsDeleted == false); let ThreatActorsWithThatName = (ThreatIntelObjects | where StixType == 'threat-actor' | where Data.name == THREAT_ACTOR_NAME | extend tlId = tostring(Data.id) | extend ActorName = tostring(Data.name) | summarize arg_max(TimeGenerated, *) by Id | where IsDeleted == false); let AllRelationships = (ThreatIntelObjects | where StixType == 'relationship' | extend tlSourceRef = tostring(Data.source_ref) | extend tlTargetRef = tostring(Data.target_ref) | extend tlId = tostring(Data.id) | summarize arg_max(TimeGenerated, *) by Id | where IsDeleted == false); let SourceRelationships = (ThreatActorsWithThatName | join AllRelationships on $left.tlId == $right.tlSourceRef | join ThreatIntelObjectsPlus on $left.tlTargetRef == $right.tlId); let TargetRelationships = (ThreatActorsWithThatName | join AllRelationships on $left.tlId == $right.tlTargetRef | join ThreatIntelObjectsPlus on $left.tlSourceRef == $right.tlId); SourceRelationships | union TargetRelationships | project ActorName, StixTypes, ObservableValue, Pattern, Tags, feedSource You now have all the information your organization has available about Sangria Tempest, correlated to maximize your understanding of the threat actor and its associations to threat infrastructure and activity. Demo 2: Curate and attribute objects We have created new UX to streamline TI object creation, which includes the capability to attribute to other objects, so while you are creating a new IoC, you can also attribute that indicator to a Threat Actor, all from one place. To create a new TI object and attribute it to one or multiple threat actors, follow the steps below: Go to Add new a TI Object. In the Context menu, select any object type. Enter all the required information in the fields on the right-hand side for your selected indicator type. While creating a new TI object, you can do TI object curation. This includes defining the relationship. You can also quickly duplicate TI objects, making it easier for those who create multiple TI objects daily. Please note that we also introduced an “Add and duplicate” button to allow customers to create multiple TI objects with the same metadata to streamline a manual bulk process. Demo 3: New supported IoC types The attack pattern builder now supports the creation of four new indicator types. These enable customers to build more specific attack patterns that boost understanding of and organizational knowledge around threats. These new indicators include: X509 certificate X509 certificates are used to authenticate the identity of devices and servers, ensuring secure communication over the internet. They are crucial in preventing man-in-the-middle attacks and verifying the legitimacy of websites and services. For instance, if a certificate is suddenly replaced or a new, unknown certificate appears, it could indicate a compromised server or a malicious actor attempting to intercept communications. JA3 JA3 fingerprints are unique identifiers generated from the TLS/SSL handshake process. They help in identifying specific applications and tools used in network traffic, making it easier to detect malicious activities For example, if a network traffic analysis reveals a JA3 fingerprint matching that of the Cobalt Strike tool, it could indicate an ongoing cyber attack. JA3S JA3S fingerprints extend the capabilities of JA3 by also including server-specific characteristics in the fingerprinting process. This provides a more comprehensive view of the network traffic and helps in identifying both client and server-side threats For instance, if a server starts communicating with an unknown external IP address using a specific JA3S fingerprint, it could be a sign of a compromised server or data exfiltration attempt. User agent User Agents provide information about the client software making requests to a server, such as the browser or operating system. They are useful in identifying and profiling devices and applications accessing a network For example, if a User Agent string associated with a known malicious browser extension appears in network logs, it could indicate a compromised device. Conclusion: The ability to ingest, curate, and establish relationships between various threat intelligence objects such as Threat Actors, Attack Patterns, and Identities provides a powerful framework for incident responders and threat intelligence analysts. The use of STIX objects not only improves interoperability and sharing of threat intelligence but also empowers organizations to hunt and investigate threats more efficiently. As customers adopt these new capabilities, they will find themselves better equipped to understand the full context of an attack and build robust defenses against future threats. With the public preview of Threat Intelligence (TI) object support, organizations are encouraged to explore these new tools and integrate them into their security operations, taking the first step towards a more informed and proactive approach to cybersecurity.Ignite 2025: New Microsoft Sentinel Connectors Announcement

With more data and intelligence than ever, it’s often a challenge to manage it all while making sure you’re maximizing its value for security investigations. We’ve made it easier for customers leveraging Microsoft’s SIEM and XDR. Now, customers can create custom detections that correlate threat intelligence from feeds brought in through the SIEM with their XDR data, without the need to ingest their XDR data as well. Why this matters Traditionally, correlating threat intelligence with endpoint and identity data required ingesting large volumes of XDR data into the SIEM. While effective, this approach often drove up ingestion and retention costs. The new capability eliminates that dependency, allowing security teams to: Reduce costs – Avoid unnecessary data ingestion charges while still leveraging XDR insights for detection. Accelerate detection – Query XDR and SIEM data seamlessly in near real time, enabling faster identification of threats. Maintain flexibility – Use custom detection rules to tailor alerts to your organization’s unique threat landscape. How it works Threat intelligence integration – Use curated threat indicators from Microsoft or your own threat intelligence platform (TIP) to power detections. Build custom detection rules that query both Sentinel and Defender XDR tables directly. This means you can match threat intelligence indicators—such as malicious IPs, domains, or file hashes (including from third party/non-Microsoft IOCs)—against Defender XDR telemetry without duplicating data in Sentinel. These rules can run on a schedule or in near real time, ensuring timely detection of suspicious activity. Examples of KQL Queries that can be used with Custom Detections, providing the following capabilities: Query the new TI tables (ThreatIntelIndicators and ThreatIntelObjects). Correlate with Defender XDR data without ingestion into Sentinel using Custom Detection rules. Enrich detections with threat actor context for better triage. Example 1: This query identifies any Domain indicators of compromise (IOCs) from threat intelligence (TI) by searching for matches in DeviceNetworkEvents. let dt_lookBack = 1h; // device events time window (how far back to look at traffic) let ioc_lookBack = 14d; // TI time window (how far back to read indicators) let DeviceNetworkEvents_ = DeviceNetworkEvents | where isnotempty(RemoteUrl) | where Timestamp >= ago(dt_lookBack) | where ActionType !has "ConnectionFailed" | extend Domain = tostring(parse_url(tolower(RemoteUrl)).Host) | where isnotempty(Domain) | project-rename DeviceNetworkEvents_TimeGenerated = Timestamp; let DeviceNetworkEventDomains = DeviceNetworkEvents_ | distinct Domain | summarize make_list(Domain); ThreatIntelIndicators | extend IndicatorType = replace(@"\[|\]|\""", "", tostring(split(ObservableKey, ":", 0))) | where IndicatorType == "domain-name" | extend DomainName = tolower(ObservableValue) | where TimeGenerated >= ago(ioc_lookBack) | extend IndicatorId = tostring(split(Id, "--")[2]) | where DomainName in (DeviceNetworkEventDomains) | summarize LatestIndicatorTime = arg_max(TimeGenerated, *) by Id, ObservableValue | where IsActive and (ValidUntil > now() or isempty(ValidUntil)) | extend Description = tostring(parse_json(Data).description) | extend TrafficLightProtocolLevel = tostring(parse_json(AdditionalFields).TLPLevel) | where Description !contains_cs "State: inactive;" and Description !contains_cs "State: falsepos;" | project-reorder *, IsActive, Tags, TrafficLightProtocolLevel, DomainName, Type | join kind=innerunique (DeviceNetworkEvents_) on $left.DomainName == $right.Domain | where DeviceNetworkEvents_TimeGenerated < ValidUntil | summarize DeviceNetworkEvents_TimeGenerated = arg_max(DeviceNetworkEvents_TimeGenerated, *) by IndicatorId | project DeviceNetworkEvents_TimeGenerated, IndicatorId, Url = RemoteUrl, Confidence, Description, Tags, TrafficLightProtocolLevel, ActionType, DeviceId, DeviceName, InitiatingProcessAccountUpn, InitiatingProcessCommandLine, RemoteIP, RemotePort, ReportId | extend Name = tostring(split(InitiatingProcessAccountUpn, '@', 0)[0]), UPNSuffix = tostring(split(InitiatingProcessAccountUpn, '@', 1)[0]) | extend Timestamp = DeviceNetworkEvents_TimeGenerated, UserPrincipalName = InitiatingProcessAccountUpn Example 2: Detect Malicious File Hashes Using ThreatIntelIndicators.

Co-author - Ashwin Patil Security teams today face an overwhelming challenge: every data point is now a potential security signal and SOCs are drowning in complex logs, trying to find the needle in the haystack. Microsoft Sentinel User and Entity Behavior Analytics (UEBA) brings the power of AI to automatically surface anomalous behaviors, helping analysts cut through the noise, save time, and focus on what truly matters. Microsoft Sentinel UEBA has already helped SOCs uncover insider threats, detect compromised accounts, and reveal subtle attack signals that traditional rule-based methods often miss. These capabilities were previously powered by a core set of high-value data sources - such as sign-in activity, audit logs, and identity signals - that consistently delivered rich context and accurate detections. Today, we’re excited to announce a major expansion: Sentinel UEBA now supports six new data sources including Microsoft first- and third-party platforms like Azure, AWS, GCP, and Okta, bringing deeper visibility, broader context, and more powerful anomaly detection tailored to your environment. This isn’t just about ingesting more logs. It’s about transforming how SOCs understand behavior, detect threats, and prioritize response. With this evolution, analysts gain a unified, cross-platform view of user and entity behavior, enabling them to correlate signals, uncover hidden risks, and act faster with greater confidence. Newly supported data sources are built for real-world security use cases: Authentication activities MDE DeviceLogonEvents – Ideal for spotting lateral movement and unusual access. AADManagedIdentitySignInLogs – Critical for spotting stealthy abuse of non - human identities. AADServicePrincipalSignInLogs - Identifying anomalies in service principal usage such as token theft or over - privileged automation. Cloud platforms & identity management AWS CloudTrail Login Events - Surfaces risky AWS account activity based on AWS CloudTrail ConsoleLogin events and logon related attributes. GCP Audit Logs - Failed IAM Access, Captures denied access attempts indicating reconnaissance, brute force, or privilege misuse in GCP. Okta MFA & Auth Security Change Events – Flags MFA challenges, resets, and policy modifications that may reveal MFA fatigue, session hijacking, or policy tampering. Currently supports the Okta_CL table (unified Okta connector support coming soon). These sources feed directly into UEBA’s entity profiles and baselines - enriching users, devices, and service identities with behavioral context and anomalies that would otherwise be fragmented across platforms. This will complement our existing supported log sources - monitoring Entra ID sign-in logs, Azure Activity logs and Windows Security Events. Due to the unified schema available across data sources, UEBA enables feature-rich investigation and the capability to correlate across data sources, cross platform identities or devices insights, anomalies, and more. AI-powered UEBA that understands your environment Microsoft Sentinel UEBA goes beyond simple log collection - it continuously learns from your environment. By applying AI models trained on your organization’s behavioral data, UEBA builds dynamic baselines and peer groups, enabling it to spot truly anomalous activity. UBEA builds baselines from 10 days (for uncommon activities) to 6 months, both for the user and their dynamically calculated peers. Then, insights are surfaced on the activities and logs - such as an uncommon activity or first-time activity - not only for the user but among peers. Those insights are used by an advanced AI model to identify high confidence anomalies. So, if a user signs in for the first time from an uncommon location, a common pattern in the environment due to reliance on global vendors, for example, then this will not be identified as an anomaly, keeping the noise down. However, in a tightly controlled environment, this same behavior can be an indication of an attack and will surface in the Anomalies table. Including those signals in custom detections can help affect the severity of an alert. So, while logic is maintained, the SOC is focused on the right priorities. How to use UEBA for maximum impact Security teams can leverage UEBA in several key ways. All the examples below leverage UEBA’s dynamic behavioral baselines looking back up to 6 months. Teams can also leverage the hunting queries from the "UEBA essentials" solution in Microsoft Sentinel's Content Hub. Behavior Analytics: Detect unusual logon times, MFA fatigue, or service principal misuse across hybrid environments. Get visibility into geo-location of events and Threat Intelligence insights. Here’s an example of how you can easily discover Accounts authenticating without MFA and from uncommonly connected countries using UEBA behaviorAnalytics table: BehaviorAnalytics | where TimeGenerated > ago(7d) | where EventSource == "AwsConsoleSignIn" | where ActionType == "ConsoleLogin" and ActivityType == "signin.amazonaws.com" | where ActivityInsights.IsMfaUsed == "No" | where ActivityInsights.CountryUncommonlyConnectedFromInTenant == True | evaluate bag_unpack(UsersInsights, "AWS_") | where InvestigationPriority > 0 // Filter noise - uncomment if you want to see low fidelity noise | project TimeGenerated, _WorkspaceId, ActionType, ActivityType, InvestigationPriority, SourceIPAddress, SourceIPLocation, AWS_UserIdentityType, AWS_UserIdentityAccountId, AWS_UserIdentityArn Anomaly detection Identify lateral movement, dormant account reactivation, or brute-force attempts, even when they span cloud platforms. Below are examples of how to discover UEBA Anomalous AwsCloudTrail anomalies via various UEBA activity insights or device insights attributes: Anomalies | where AnomalyTemplateName in ( "UEBA Anomalous Logon in AwsCloudTrail", // AWS ClousTrail anomalies "UEBA Anomalous MFA Failures in Okta_CL", "UEBA Anomalous Activity in Okta_CL", // Okta Anomalies "UEBA Anomalous Activity in GCP Audit Logs", // GCP Failed IAM access anomalies "UEBA Anomalous Authentication" // For Authentication related anomalies ) | project TimeGenerated, _WorkspaceId, AnomalyTemplateName, AnomalyScore, Description, AnomalyDetails, ActivityInsights, DeviceInsights, UserInsights, Tactics, Techniques Alert optimization Use UEBA signals to dynamically adjust alert severity in custom detections—turning noisy alerts into high-fidelity detections. The example below shows all the users with anomalous sign in patterns based on UEBA. Joining the results with any of the AWS alerts with same AWS identity will increase fidelity. BehaviorAnalytics | where TimeGenerated > ago(7d) | where EventSource == "AwsConsoleSignIn" | where ActionType == "ConsoleLogin" and ActivityType == "signin.amazonaws.com" | where ActivityInsights.FirstTimeConnectionViaISPInTenant == True or ActivityInsights.FirstTimeUserConnectedFromCountry == True | evaluate bag_unpack(UsersInsights, "AWS_") | where InvestigationPriority > 0 // Filter noise - uncomment if you want to see low fidelity noise | project TimeGenerated, _WorkspaceId, ActionType, ActivityType, InvestigationPriority, SourceIPAddress, SourceIPLocation, AWS_UserIdentityType, AWS_UserIdentityAccountId, AWS_UserIdentityArn, ActivityInsights | evaluate bag_unpack(ActivityInsights) Another example shows anomalous key vault access from service principal with uncommon source country location. Joining this activity with other alerts from the same service principle increases fidelity of the alerts. You can also join the anomaly UEBA Anomalous Authentication with other alerts from the same identity to bring the full power of UEBA into your detections. BehaviorAnalytics | where TimeGenerated > ago(1d) | where EventSource == "Authentication" and SourceSystem == "AAD" | evaluate bag_unpack(ActivityInsights) | where LogonMethod == "Service Principal" and Resource == "Azure Key Vault" | where ActionUncommonlyPerformedByUser == "True" and CountryUncommonlyConnectedFromByUser == "True" | where InvestigationPriority > 0 Final thoughts This release marks a new chapter for Sentinel UEBA—bringing together AI, behavioral analytics, and cross-cloud and identity management visibility to help defenders stay ahead of threats. If you haven’t explored UEBA yet, now’s the time. Enable it in your workspace settings and don’t forget to enable anomalies as well (in Anomalies settings). And if you’re already using it, these new sources will help you unlock even more value. Stay tuned for our upcoming Ninja show and webinar (register at aka.ms/secwebinars), where we’ll dive deeper into use cases. Until then, explore the new sources, use the UEBA workbook, update your watchlists, and let UEBA do the heavy lifting.

Security operations are undergoing significant transformation driven by the introduction of AI and a rapidly evolving threat landscape. With Microsoft Sentinel data lake now generally available, organizations can centralize all their security data in a purpose-built security data lake. This helps optimize costs, simplify data management, and accelerate the adoption of AI in security operations. This empowers defenders to transcend legacy security controls, adopting advanced analytics and automation for more dynamic and effective protection. A key advantage of the Sentinel data lake is its cost-efficiency, making it ideal for ingesting and retaining large volumes of security logs, such as network logs, without incurring high expenses or compromising coverage. By storing all security data in a unified, cost-effective data lake, organizations gain comprehensive, long-term visibility for historical threat hunting and TI matching, enabling investigations across extended timelines without the prohibitive costs of traditional analytics solutions. In this blog we will explore how security teams can leverage KQL jobs in Sentinel data lake to automate threat hunting and threat intelligence matching across network logs, enabling scalable, cost-effective, and continuous threat detection. By doing so, SOCs can efficiently process large volumes of data and transform raw logs into actionable insights efficiently with minimal manual intervention. What are KQL jobs? KQL jobs in Sentinel data lake are automated one-time or scheduled jobs that run Kusto Query Language (KQL) queries on data lake. These jobs help security teams investigate and hunt for threats more easily by automating processes like checking logs against known threat data. By automating tasks such as IOC matching with historical or high-volume data, analysts are able to concentrate on higher-value activities. This results in more effective threat detection and response. The next section demonstrates how to use the data lake for Threat Intelligence (TI) matching across network logs. IOC matching on network log on data lake Network logs, such as firewall and proxy data, are essential for uncovering advanced threats and supporting investigations. However, storing all this data in the analytics tier is often expensive, leading to reduced retention and potential blind spots. With Sentinel data lake, SOCs can store all their raw telemetry, at a fraction of the cost, making it possible to hunt for threats across a much broader timeline without financial constraints. However, simply storing data isn’t enough. To turn raw logs into actionable insights, SOC teams need to automate both summarization and threat intelligence (TI) matching. Scheduled KQL jobs make this possible by scanning new data in a schedule as it arrives in the data lake, surfacing suspicious activity for analyst review. Schedule KQL job for TI matching on network logs Here’s a practical example of how a SOC can use a scheduled KQL job to summarize network activity and correlate it with threat intelligence indicators. In this scenario, a KQL job is run to identify network log entries from Palo Alto firewalls that match known malicious IPs from ThreatIntelIndicators table. The output provides the complete network log row, enriched with relevant threat intelligence fields for further investigation and response. Create your query: let IPRegex = '[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}'; let dt_lookBack = 75m; // Look back 1 hour for CommonSecurityLog events let ioc_lookBack = 14d; // Look back 14 days for threat intelligence indicators // Fetch threat intelligence indicators related to IP addresses let IP_Indicators = ThreatIntelIndicators //extract key part of kv pair | extend IndicatorType = replace(@"\[|\]|\""", "", tostring(split(ObservableKey, ":", 0))) | where IndicatorType in ("ipv4-addr", "ipv6-addr", "network-traffic") | extend NetworkSourceIP = toupper(ObservableValue) | extend TrafficLightProtocolLevel = tostring(parse_json(AdditionalFields).TLPLevel) | where TimeGenerated >= ago(ioc_lookBack) | extend TI_ipEntity = iff(isnotempty(NetworkSourceIP), NetworkSourceIP, NetworkSourceIP) | extend TI_ipEntity = iff(isempty(TI_ipEntity) and isnotempty(NetworkSourceIP), NetworkSourceIP, TI_ipEntity) | where ipv4_is_private(TI_ipEntity) == false and TI_ipEntity !startswith "fe80" and TI_ipEntity !startswith "::" and TI_ipEntity !startswith "127." | summarize LatestIndicatorTime = arg_max(TimeGenerated, *) by Id, ObservableValue | where IsActive and (ValidUntil > now() or isempty(ValidUntil)); // Perform a join between IP indicators and CommonSecurityLog events IP_Indicators | project-reorder *, Tags, TrafficLightProtocolLevel, NetworkSourceIP, TI_ipEntity // Use innerunique to keep performance fast and result set low, as we only need one match to indicate potential malicious activity that needs investigation | join kind=innerunique ( CommonSecurityLog | where TimeGenerated >= ago(dt_lookBack) | extend MessageIP = extract(IPRegex, 0, Message) | extend CS_ipEntity = iff((not(ipv4_is_private(SourceIP)) and isnotempty(SourceIP)), SourceIP, DestinationIP) | extend CS_ipEntity = iff(isempty(CS_ipEntity) and isnotempty(MessageIP), MessageIP, CS_ipEntity) | extend CommonSecurityLog_TimeGenerated = TimeGenerated ) on $left.TI_ipEntity == $right.CS_ipEntity // Filter out logs that occurred after the expiration of the corresponding indicator | where CommonSecurityLog_TimeGenerated < ValidUntil // Group the results by IndicatorId and CS_ipEntity, and keep the log entry with the latest timestamp | summarize CommonSecurityLog_TimeGenerated = arg_max(CommonSecurityLog_TimeGenerated, *) by Id, CS_ipEntity // Select the desired output fields | project timestamp = CommonSecurityLog_TimeGenerated, SourceIP, DestinationIP, MessageIP, Message, DeviceVendor, DeviceProduct, Id, ValidUntil, Confidence, TI_ipEntity, CS_ipEntity, LogSeverity, DeviceAction Source: Microsoft Sentinel GitHub repo Before submitting a KQL job you may want to test your query interactively, using the KQL queries page: Create a KQL job: To match against new logs periodically, we would like to schedule this job to run every hour to summarize network log and match against latest IOCs in ThreatInelIndicators. To avoid missing any logs, I suggest adding an overlap between lookback and schedules, to make sure all logs are scanned. For example, you can set lookback of the last 75 minutes and execute job runs every 60 minutes. KQL jobs can run ad-hoc or be scheduled based on your preferred frequency (by minutes, hourly, daily, weekly or monthly), automatically summarizing new network activity and highlighting matches with known malicious indicators. Analysts can then focus on the most relevant events, accelerating investigations and reducing noise. Results are automatically available in the analytics tier and can be used to set up an automated detection using Analytics rules. The cost of running KQL jobs in Sentinel data lake depends on the volume of data scanned and how frequently the jobs run. Data lake KQL queries and jobs are priced at $0.005 per GB scanned. For example, if a KQL job scans 1 TB of data daily, the monthly cost would be around $150 USD. This pricing model allows organizations to perform large-scale threat hunting and intelligence matching without the high expenses typically associated with traditional SIEMs. $0.005 per GB scanned. For more details around Microsoft Sentinel data lake costs for KQL queries and jobs, see https://azure.microsoft.com/en-us/pricing/calculator. Summary and next steps Threat hunting at scale within Sentinel data lake is simplified with KQL jobs. SOC teams can use this method for various hunting or anomaly detection scenarios such as efficiently aggregating and correlating network logs with threat intelligence, enhancing visibility, agility, and assurance, and transforming raw telemetry into actionable security insights. KQL jobs provide several benefits: Continuous threat coverage: Scheduled jobs utilizing KQL automatically correlate high-volume logs located directly in the data lake with up-to-date threat intelligence. This process helps minimize detection gaps and blind spots. Efficient use of resources: Automating TI matching saves analysts from repetitive queries, allowing them to focus on investigating validated alerts rather than sifting through raw logs. Faster response times: Suspicious connections flagged by minutes or every hour enable quicker triage and containment before threats escalate. Historical context: Matches are retained against long-term or high volume logs, enabling analysts to trace back patterns of malicious activity and support deeper investigations.
