Sentinel-Threat Intelligence Feeds Integration to strengthen Threat Detection & Proactive Hunting.
Combining threat intelligence feeds is important for detecting threats and identifying Indicators of Compromise (IOCs) in various scenarios. Here are some key situations where this approach is advantageous: Comprehensive Threat Detection Integrating multiple threat intelligence feeds can cover a wider range of threats. Different feeds may provide unique insights into malicious activities, IP addresses, domain names, and other IOCs. Reducing False Positives Combining feeds helps cross-verify data, decreasing the likelihood of false positives. This ensures that security teams focus on actual threats rather than inaccurate alerts. Enhanced Contextual Analysis Multiple feeds can offer richer context around threats, including tactics, techniques, and procedures (TTPs) used by attackers. This helps in understanding the threat landscape better and making informed decisions. Real-Time Threat Response Integrating feeds allows for real-time updates on emerging threats. This enables security teams to respond swiftly to new threats and mitigate potential damage. Proactive Threat Hunting Threat hunters can use combined feeds to identify patterns and anomalies that might indicate a threat. This proactive approach assists in detecting threats before they can cause significant harm. Improved Threat Intelligence Sharing Combining feeds from different sources, such as government agencies, commercial vendors, and open-source communities, enhances the overall quality and reliability of threat intelligence. Example Query in Microsoft Sentinel Here's an example of how you might combine two threat intelligence feeds using the coalesce function in KQL: _______________________________________________________________________________________ ThreatIntelFeed1 | extend CombinedIndicator = coalesce(ThreatIntelFeed1.Indicator, ThreatIntelFeed2.Indicator) | extend CombinedDescription = coalesce(ThreatIntelFeed1.Description, ThreatIntelFeed2.Description) | project CombinedIndicator, CombinedDescription _________________________________________________________________________________________ In the above example coalsce function is used. The coalesce function in Kusto Query Language (KQL) is used to evaluate a list of expressions and return the first non-null (or non-empty for strings) expression. This function is particularly useful in Microsoft Sentinel for handling data where some fields might be missing or null. Syntax coalesce(arg, arg_2, [arg_3, ...]) arg: The expression to be evaluated. All arguments must be of the same type. Maximum of 64 arguments is supported. Functions of coalesce in Sentinel Threat Intelligence Feeds Handling Missing Data: It helps in filling gaps where data might be missing by providing a fallback value. For example, if one threat intelligence feed lacks an IP address, coalesce can pull it from another feed. Data Normalization: Combines multiple fields into one, ensuring that you always have a value to work with. This is useful when different feeds provide similar data in different fields. Simplifying Queries: Reduces the need for complex conditional logic to handle null values, making queries more readable and maintainable. Let’s look at Threat Intelligence Analytic rule where caolsec function is used. The query combines threat intelligence indicators with DNS data to identify potential malicious activity. It ensures that only relevant and recent indicators are considered and matches them with DNS queries to detect suspicious behavior. This query ensures that you obtain the most comprehensive data by taking the first non-null value from either feed. Let's break down this KQL query step by step: Define Lookback Periods dt_lookBack: Sets a lookback period of 1 hour for DNS data. ioc_lookBack: Sets a lookback period of 14 days for threat intelligence indicators. Extract Relevant Threat Intelligence Indicators ThreatIntelligenceIndicator: Filters threat intelligence indicators generated within the last 14 days and not expired. arg_max(TimeGenerated, *) by IndicatorId: Summarizes to get the latest indicator for each IndicatorId. Active == true: Filters only active indicators. coalesce(NetworkIP, NetworkDestinationIP, NetworkSourceIP, EmailSourceIpAddress, "NO_IP"): Combines various IP fields into a single IoC field, defaulting to "NO_IP" if none are present. where IoC != "NO_IP": Filters out entries without valid IP addresses. Join with DNS Data join kind=innerunique: Joins the threat intelligence indicators with DNS data using an inner unique join to keep performance fast and result set low. _Im_Dns(starttime=ago(dt_lookBack)): Retrieves DNS data from the last hour. where isnotempty(DnsResponseName): Filters DNS records with non-empty response names. summarize imDns_mintime=min(TimeGenerated), imDns_maxtime=max(TimeGenerated) by SrcIpAddr, DnsQuery, DnsResponseName, Dvc, EventProduct, EventVendor: Summarizes DNS data by various fields. extract_all(@'(\d+\.\d+\.\d+\.\d+)', DnsResponseName): Extracts all IP addresses from the DNS response name. mv-expand IoC = addresses to typeof(string): Expands the extracted IP addresses into individual rows. Combined KQL looks like below _________________________________________________________________________________________ let dt_lookBack = 1h; let ioc_lookBack = 14d; let IP_TI = ThreatIntelligenceIndicator | where TimeGenerated >= ago(ioc_lookBack) and ExpirationDateTime > now() | summarize LatestIndicatorTime = arg_max(TimeGenerated, *) by IndicatorId | where Active == true | extend IoC = coalesce(NetworkIP, NetworkDestinationIP, NetworkSourceIP,EmailSourceIpAddress,"NO_IP") | where IoC != "NO_IP" ; IP_TI | join kind=innerunique // using innerunique to keep perf fast and result set low, we only need one match to indicate potential malicious activity that needs to be investigated ( _Im_Dns(starttime=ago(dt_lookBack)) | where isnotempty(DnsResponseName) | summarize imDns_mintime=min(TimeGenerated), imDns_maxtime=max(TimeGenerated) by SrcIpAddr, DnsQuery, DnsResponseName, Dvc, EventProduct, EventVendor | extend addresses = extract_all (@'(\d+\.\d+\.\d+\.\d+)', DnsResponseName) | mv-expand IoC = addresses to typeof(string) ) on IoC _________________________________________________________________________________________ Summary This article explores the importance of combining threat intelligence feeds to improve security operations. Key benefits include extending threat coverage, reducing false positives, and enhancing contextual analysis through detailed insights into attackers' tactics and techniques. The integration process also facilitates real-time threat updates and enables better collaboration between different intelligence sources. An example is provided using KQL (Kusto Query Language) to demonstrate how threat intelligence feeds can be combined effectively within Microsoft Sentinel. The query showcases steps like defining lookback periods, extracting relevant indicators, and correlating them with DNS data through an inner unique join. By leveraging this method, organizations can efficiently identify potential malicious activities and strengthen their threat response capabilities. The content emphasizes that integrating threat feeds is not just a technical function but a strategic necessity to fortify organizations against evolving cyber threats.End-to-End automation of Onboarding a Virtual Machine to a Defender for servers.

Understanding ARM Templates ARM templates are JSON files that define the resources needed for your applications. They allow for infrastructure as code, making deployment and management more efficient and consistent. By leveraging ARM templates, you can automate the creation and configuration of your Sentinel GCP data connector. Prerequisites Before proceeding, ensure you have: An active Azure subscription Admin access to both your Azure(Microsoft Sentinel Contributor permissions) and GCP accounts. Basic knowledge of JSON and ARM templates Create a custom table in Azure Sentinel Creating a Custom Table in Azure Sentinel For more information about the custom table creation experience, please see the documentation. To create a custom table in Azure Sentinel: Navigate to the Azure Sentinel workspace in the Azure portal. Select Tables from the left-hand menu. Click on + Create to add a new table. Define the table schema according to the log data you plan to ingest. This includes fields such as timestamp, log level, source, and message. Save the table and ensure it is available for log ingestion. Step-by-Step Process 1. Setting Up Pub/Sub in GCP To start, you need to create a Pub/Sub topic and subscription in GCP: Navigate to the GCP console. Select Pub/Sub from the menu. Create a new topic and name it appropriately, such as `sentinel-logs`. Under the topic, create a subscription. This subscription will pull the logs from GCP and push them to Azure Sentinel. 2. Configuring Audit Log Streaming Next, configure GCP to stream audit logs to your Pub/Subtopic: Navigate to the Logging section in the GCP console. Select the desired audit logs you wish to export. Set the destination as your Pub/Subtopic. 3. Creating the ARM Template The ARM template will define the resources needed to connect GCP logs to Azure Sentinel. Use the attached template (in the last section), update the parameters based on the instructions given in the comment section (search word “Modify” to go to relevant parameters that needs to be modified) This template creates a linked service in Azure Sentinel that connects to the specified GCP Pub/Sub subscription. 4. Deploying the ARM Template Deploy the ARM template through the Azure portal or using Azure CLI: In the Azure portal, navigate to the 'Deploy a custom template' section. Click on Build your own template in the editor Delete existing content Paste the ARM template JSON file and fill in the required parameters. Click on save. Enter the resource group, workspace name and workspace location details. Click 'Review + Create' and then 'Create' to deploy the template. Once the template is deployed, you can search for the data connector Configure the Data connector Open the data connector page Click on Add new collector and enter the GCP account details then click connect. Verifying the Connection Once deployed, verify that logs are being ingested into Azure Sentinel: Check the Azure Sentinel workspace for incoming logs. Ensure that the logs from the specified GCP audit logs are appearing as expected. Troubleshoot any missing logs by reviewing Pub/Sub configurations and subscriptions. Advanced Configuration For advanced users, consider customizing the ARM template to ingest other types of logs or incorporate additional GCP services: Modify the Pub/Subtopic to include additional log sources. Create multiple linked services within the ARM template for different log types. Incorporate custom parsing and transformation rules within Azure Sentinel for GCP logs. Conclusion Building a custom Sentinel GCP data connector using an ARM template allows for more flexibility and control over the types of logs ingested from GCP. By following this guide, you can ensure that your cloud infrastructure is monitored comprehensively, enhancing your security posture and operational efficiency. We hope this guide empowers you to leverage the full potential of Azure Sentinel and GCP integration. Should you have any further questions or require assistance, please do not hesitate to reach out.

Internet Information Services (IIS) stores user activity in log files (“IIS logs”). These logs can be useful for many purposes, from simple retention, statistical analysis and site mapping through to security-focused use cases and detections like brute force attacks, detection of code injection, Web shell attacks and more. The Azure Monitor Agent can collect IIS log files when configured with a data collection rule (DCR), with IIS logs supported as a key input log type. You can find out how to collect log data in the article Collect data with Azure Monitor Agent. IIS numbers its websites internally, and stores logs for each site in a numbered folder by default. If you’re just using the Default Web Site, that’s ID 1, and the log file folder will default to C:\InetPub\logs\LogFiles\W3SVC1. AMA with a default DCR is very happy to collect from this location. But what if you’re hosting more than just 1 website, and need to collect logs from more than one location, as shown in the picture below? The default configuration for the DCR won’t cover those logs, so to configure our Azure Monitor Agent to pick up more locations, we can edit the DCR to add more. We’re going to use the existing rule as our template to add more folders. Here’s how: In the Azure Portal, find and open the DCR object for the IIS logs o You can type its name directly into the Search box at the top, if you know it (or a portion of it) o Or type ‘Data Collection Rules’ and open that page to see a full list Click on Export template. Uncheck the include parameters box o Note: Timing can be tricky - you should be left with a page which lists Parameters (0). Click on deploy. Click on Edit Template Add additional IIS log folder locations under the iisLogs logDirectories section as show below. o Remember we’re using JSON array syntax, so each entry except the last needs to be followed by a comma, e.g. "logDirectories": [ "c:\\one", "c:\\two", "c:\\three" ] o And each backslash in the path needs to be doubled. Click Save when you’ve added your desired folders Click on Review + create Click Create Finally, when you open the JSON view of the DCR you will see multiple directories added in the IIS logs section. This configuration of DCR will help you to collect logs from multiple IIS directories. Internet Information Services (IIS) stores user activity in log files (“IIS logs”).

As organizations move to the cloud and adopt SaaS applications, identities are becoming increasingly crucial for accessing resources. Cybercriminals exploit legitimate and authorized identities to steal data and access credentials through methods like phishing, malware, data breaches, brute-force/password spray attacks, and prior compromises. As in past years, password-based attacks on users constitute most identity-related attacks. As MFA blocks most password-based attacks, threat actors are shifting their focus, moving up the cyberattack chain in three ways: 1) attacking infrastructure, 2) bypassing authentication, and 3) exploiting applications. They are leaning more heavily into adversary-in-the-middle (AiTM) phishing attacks and token theft. Over the last year, as Microsoft Digital Defense Report (MDDR 2024) a 146% rise in AiTM phishing attacks. In AiTM attack , the attackers steal tokens instead of passwords. The Frameworks used by attackers go far beyond credential phishing, by inserting malicious infrastructure between the user and the legitimate application the user is trying to access. When the user is phished, the malicious infrastructure captures both the credentials of the user, and the token. By compromising and replaying a token issued to an identity that has already completed multifactor authentication, the threat actor satisfies the validation of MFA and access is granted to organizational resources accordingly. Now it is imperative that tokens must be protected from token theft. Let us understand more on tokens. An Entra identity token is a security token issued by Microsoft Entra ID for authentication and authorization. There are several types: Access Tokens: Grant access to resources on behalf of an authenticated user, containing user and resource information. ID Tokens: Authenticate users, issued in the OpenID Connect flow, containing user identity and authentication details. Refresh Tokens: Obtain new access tokens without re-authentication, usually issued with access tokens and have a longer lifespan. Ensuring Token Security By following best practices, you can significantly enhance the security of your tokens and protect your applications from unauthorized access. Use Secure Transmission: Always transmit tokens over secure channels such as HTTPS to prevent interception by unauthorized parties. Token Binding: Implement Token Protection (formerly known as token binding) to cryptographically tie tokens to client secrets. This prevents token replay attacks from different devices. Conditional Access Policies: Use Conditional Access policies to enforce compliant network checks. This ensures that tokens are only used from trusted networks and devices. Continuous Access Evaluation (CAE): Implement CAE to continuously evaluate the security state of the session. This helps in detecting and revoking tokens if there are changes in the user's security posture, such as network location changes. Short Token Lifetimes: Use short lifetimes for access tokens and refresh tokens to limit the window of opportunity for attackers. Secure Storage: Store tokens securely on the client side, using secure storage mechanisms provided by the operating system, such as Keychain on iOS or Keystore on Android. Regular Audits and Monitoring: Regularly audit token usage and monitor for any unusual activity. This helps in early detection of potential security breaches. Now we will discuss Entra ID new features for Token Protection. Token protection using conditional access : This feature will provide refresh token protection. Compliant network check with Conditional Access: This feature will provide both refresh token and Access token protection. Token protection using conditional access: Token protection (sometimes referred to as token binding in the industry) attempts to reduce attacks using token theft by ensuring a token is usable only from the intended device. When an attacker is able to steal a token, by hijacking or replay, they can impersonate their victim until the token expires or is revoked. Token theft is thought to be a relatively rare event, but the damage from it can be significant. Token protection creates a cryptographically secure tie between the token and the device (client secret) it's issued to. Without the client secret, the bound token is useless. When a user registers a Windows 10 or newer device in Microsoft Entra ID, their primary identity is bound to the device. What this means: A policy can ensure that only bound sign-in session (or refresh) tokens, otherwise known as Primary Refresh Tokens (PRTs) are used by applications when requesting access to a resource. Token protection is currently in public preview Create a Conditional Access policy Users who perform specialized roles like those described in Privileged access security levels are possible targets for this functionality. We recommend piloting with a small subset to begin. The steps that follow help create a Conditional Access policy to require token protection for Exchange Online and SharePoint Online on Windows devices. Sign in to the Microsoft Entra admin center as at least a Conditional Access Administrator. Browse to Protection > Conditional Access > Policies. Select New policy. Give your policy a name. We recommend that organizations create a meaningful standard for the names of their policies. Under Assignments, select Users or workload identities. Under Include, select the users or groups who are testing this policy. Under Exclude, select Users and groups and choose your organization's emergency access or break-glass accounts. 6.Under Target resources > Resources (formerly cloud apps) > Include > Select resources Under Select, select the following applications supported by the preview: Office 365 Exchange Online Office 365 SharePoint Online Choose Select. 7. Under Conditions: Under Device platforms: Set Configure to Yes. Include > Select device platforms > Windows. Select Done. Under Client apps: Set Configure to Yes Under Modern authentication clients, only select Mobile apps and desktop clients. Leave other items unchecked. Select Done. 8. Under Access controls > Session, select Require token protection for sign-in sessions and select Select. 9. Confirm your settings and set Enable policy to Report-only. 10.Select Create to create to enable your policy. After administrators confirm the settings using report-only mode, they can move the Enable policy toggle from Report-only to On. Capture logs and analyze Monitoring Conditional Access enforcement of token protection before and after enforcement. Sign-in logs Use Microsoft Entra sign-in log to verify the outcome of a token protection enforcement policy in report only mode or in enabled mode. Sign in to the Microsoft Entra admin center as at least a Conditional Access Administrator. Browse to Identity > Monitoring & health > Sign-in logs. Select a specific request to determine if the policy is applied or not. Go to the Conditional Access or Report-Only pane depending on its state and select the name of your policy requiring token protection. Under Session Controls check to see if the policy requirements were satisfied or not. You can refer below link to know more about license requirements, prerequisites & limitations. Token protection in Microsoft Entra Conditional Access - Microsoft Entra ID | Microsoft Learn Enable compliant network check with Conditional Access Organizations who use Conditional Access along with the Global Secure Access, can prevent malicious access to Microsoft apps, third-party SaaS apps, and private line-of-business (LoB) apps using multiple conditions to provide defense-in-depth. These conditions might include device compliance, location, and more to provide protection against user identity or token theft. Global Secure Access introduces the concept of a compliant network within Microsoft Entra ID Conditional Access. This compliant network check ensures users connect from a verified network connectivity model for their specific tenant and are compliant with security policies enforced by administrators. The Global Secure Access Client installed on devices or users behind configured remote networks allows administrators to secure resources behind a compliant network with advanced Conditional Access controls. This compliant network feature makes it easier for administrators to manage access policies, without having to maintain a list of egress IP addresses. This removes the requirement to hairpin traffic through organization's VPN. Compliant network check enforcement Compliant network enforcement reduces the risk of token theft/replay attacks. Compliant network enforcement happens at the authentication plane (generally available) and at the data plane (preview). Authentication plane enforcement is performed by Microsoft Entra ID at the time of user authentication. If an adversary has stolen a session token and attempts to replay it from a device that is not connected to your organization’s compliant network (for example, requesting an access token with a stolen refresh token), Entra ID will immediately deny the request and further access will be blocked. Data plane enforcement works with services that support Continuous Access Evaluation (CAE) - currently, only SharePoint & Exchange Online. With apps that support CAE, stolen access tokens that are replayed outside your tenant’s compliant network will be rejected by the application in near-real time. Without CAE, a stolen access token will last up to its full lifetime (default 60-90 minutes). This compliant network check is specific to each tenant. Using this check, you can ensure that other organizations using Microsoft's Global Secure Access services can't access your resources. For example: Contoso can protect their services like Exchange Online and SharePoint Online behind their compliant network check to ensure only Contoso users can access these resources. If another organization like Fabrikam was using a compliant network check, they wouldn't pass Contoso's compliant network check. The compliant network is different than IPv4, IPv6, or geographic locations you might configure in Microsoft Entra. Administrators are not required to review and maintain compliant network IP addresses/ranges, strengthening the security posture and minimizing the ongoing administrative overhead. Enable Global Secure Access signaling for Conditional Access To enable the required setting to allow the compliant network check, an administrator must take the following steps. Sign in to the Microsoft Entra admin center as a Global Secure Access Administrator. Browse to Global Secure Access > Settings > Session management > Adaptive access. Select the toggle to Enable CA Signaling for Entra ID (covering all cloud apps). This will automatically enable CAE signaling for Office 365 (preview). Browse to Protection > Conditional Access > Named locations. a. Confirm you have a location called All Compliant Network locationswith location type Network Access. Organizations can optionally mark this location as trusted. You can refer below link to know more about license requirements, prerequisites & limitations Protect your resources behind the compliant network The compliant network Conditional Access policy can be used to protect your Microsoft and third-party applications. A typical policy will have a 'Block' grant for all network locations except Compliant Network. The following example demonstrates the steps to configure this type of policy: Sign in to the Microsoft Entra admin center as at least a Conditional Access Administrator. Browse to Protection > Conditional Access. Select Create new policy. Give your policy a name. We recommend that organizations create a meaningful standard for the names of their policies. Under Assignments, select Users or workload identities. Under Include, select All users. Under Exclude, select Users and groupsand choose your organization's emergency access or break-glass accounts. 6. Under Target resources > Include and select All resources (formerly 'All cloud apps'). If your organization is enrolling devices into Microsoft Intune, it is recommended to exclude the applications Microsoft Intune Enrollmentand Microsoft Intune from your Conditional Access policy to avoid a circular dependency. 7. Under Network. Set Configureto Yes. Under Include, select Any location. Under Exclude, select the All Compliant Network locationslocation. 8. Under Access controls: Grant, select Block Access, and select Select. 9. Confirm your settings and set Enable policy to On. 10. Select the Create button to create to enable your policy. User exclusions Conditional Access policies are powerful tools, we recommend excluding the following accounts from your policies: Emergency access or break-glass accounts to prevent lockout due to policy misconfiguration. In the unlikely scenario all administrators are locked out, your emergency-access administrative account can be used to log in and take steps to recover access. More information can be found in the article, Manage emergency access accounts in Microsoft Entra ID. Service accounts and Service principals, such as the Microsoft Entra Connect Sync Account. Service accounts are non-interactive accounts that aren't tied to any particular user. They're normally used by back-end services allowing programmatic access to applications but are also used to sign in to systems for administrative purposes. Calls made by service principals won't be blocked by Conditional Access policies scoped to users. Use Conditional Access for workload identities to define policies targeting service principals. If your organization has these accounts in use in scripts or code, consider replacing them with managed identities. Try your compliant network policy On an end-user device with the Global Secure Access client installed and running, browse to https://outlook.office.com/mail/ or https://yourcompanyname.sharepoint.com/, you have access to resources. Pause the Global Secure Access client by right-clicking the application in the Windows tray and selecting Pause. Browse to https://outlook.office.com/mail/ or https://yourcompanyname.sharepoint.com/, you're blocked from accessing resources with an error message that says You cannot access this right now.
