Manage cases from across tenants in one place
Are you managing the security needs of a large organization or a managed security service provider (MSSP)? Would you like a unified view of all the cases you are managing across these tenants? We are pleased to announce the latest addition to our case management solution, multi-tenant support, is now generally available (GA). This is the latest step in our journey towards providing a native, security-focused case management system that spans all SecOps workloads in the Microsoft Defender portal, removing customer reliance on third-party SIEM/XDR and ticketing systems. This capability is available for all Microsoft Sentinel customers that have onboarded to the Defender portal.Multi Workspace for Single tenant is now in Public Preview in Microsoft’s unified SecOps platform
We are excited to continue to expand the use cases addressed with our unified SecOps platform, which brings the capabilities of Microsoft Sentinel, Defender XDR, Security Copilot, Threat Intelligence and more into a single experience with new and more robust functionality. Now, customers can onboard and manage multiple workspaces across Microsoft Sentinel and Defender in one place. Key Benefits of Multi Workspace Experience The multi-workspace experience offers several key benefits that enhance security operations: Unified Entity View: Customers can view all relevant entity data from multiple workspaces in a single entity page, facilitating comprehensive investigations. Workspace Filtering: Users can filter data by workspace when needed, ensuring flexibility in investigations. Enhanced Context: Aggregates alerts, incidents, and timeline events from all workspaces, providing deeper insights into entity behavior. Introducing the Primary Workspace Concept A new concept in the unified SecOps platform is Primary Workspace, which acts as a central hub where Microsoft Sentinel alerts are correlated with XDR data, resulting in incidents that include both Microsoft Sentinel’s primary workspace and XDR alerts. All XDR alerts and incidents are synced back to this workspace, ensuring a cohesive and comprehensive view of security events. The XDR connector is automatically connected to the Primary Workspace upon onboarding and can be switched if necessary. One Primary Workspace must always be connected to use the unified platform effectively. Other onboarded workspaces are considered “Secondary” workspaces, with incidents created based on their individual data. We respect and protect your data boundaries- each workspace’s data will be synced with its own alerts only. Learn more: https://aka.ms/primaryWorkspace Multi Workspace Experience- Key Scenarios Onboarding multiple workspaces to the unified SecOps platform: Open the security portal: https://security.microsoft.com/ There are two options to connect workspaces, you can select either one: Option A: Connecting the workspace through the main home page: Click on” Connect a workspace” in the banner Select the workspaces you wish to onboard and click on “Next”. Select primary workspace Review the text and click on “Connect” After completing the connection, click on “Close”. Option B: Connecting the workspaces through the Settings page: Navigate to Settings and choose “Microsoft Sentinel” Click on "Connect workspace" Follow the same steps as Option A. Switching Primary Workspaces Navigate to Settings and choose "Microsoft Sentinel" On the workspace you wish to assign as Primary, click on the "3 dots" and choose "Set as primary" Confirm and proceed. Incidents and Alerts The incident queue is a single place for a SOC analyst to manage and investigate incidents. The alert queue centralized all your workspaces’ alert in the same place and provides the ability to see the alert page. In the unified queues, you are able now to view all incidents and alerts from all workloads and all workspaces and also filter by workspace. Each alert and incident are related to a single workspace to keep data boundaries. Bi-directional sync: Any change in the unified secOps portal is reflected to Sentinel portal and vice versa. Unified Entities The multi workspace aggregated view enhances entity pages in the unified portal by consolidating data from all relevant Sentinel workspaces into a single, unified experience. This feature enables security teams to gain a complete view of entity-related data without switching between workspaces, improving investigation efficiency and data accessibility. The unified entity page grants you with: Unified Entity View: Customers can see all relevant entity data from multiple workspaces in a single entity page.

Microsoft Sentinel just rolled out a powerful new public preview feature: Ingestion Rules. This feature lets you fine-tune your threat intelligence (TI) feeds before they are ingested to Microsoft Sentinel. You can now set custom conditions and actions on Indicators of Compromise (IoCs), Threat Actors, Attack Patterns, Identities, and their Relationships. Use cases include: Filter Out False Positives: Suppress IoCs from feeds known to generate frequent false positives, ensuring only relevant intel reaches your analysts. Extending IoC validity periods for feeds that need longer lifespans. Tagging TI objects to match your organization's terminology and workflows Get Started Today with Ingestion Rules To create new “Ingestion rule”, navigate to “Intel Management” and Click on “Ingestion rules” With the new Ingestion rules feature, you have the power to modify or remove indicators even before they are integrated into Sentinel. These rules allow you to act on indicators currently in the ingestion pipeline. > Click on “Ingestion rules” Note: It can take up to 15 minutes for the rule to take effect Use Case #1: Delete IOC’s with less confidence score while ingesting When ingesting IOC's from TAXII/Upload API/File Upload, indicators are imported continuously. With pre-ingestion rules, you can filter out indicators that do not meet a certain confidence threshold. Specifically, you can set a rule to drop all indicators in the pipeline with a confidence score of 0, ensuring that only reliable data makes it through. Use Case #2: Extending IOC’s The following rule can be created to automatically extend the expiration date for all indicators in the pipeline where the confidence score is greater than 75. This ensures that these high-value indicators remain active and usable for a longer duration, enhancing the overall effectiveness of threat detection and response. Use Case #3: Bulk Tagging Bulk tagging is an efficient way to manage and categorize large volumes of indicators based on their confidence scores. With pre-ingestion rules, you can set up a rule to tag all indicators in the pipeline where the confidence score is greater than 75. This automated tagging process helps in organizing indicators, making it easier to search, filter, and analyze them based on their tags. It streamlines the workflow and improves the overall management of indicators within Sentinel. Managing Ingestion rules In addition to the specific use cases mentioned, managing ingestion rules gives you control over the entire ingestion process. 1. Reorder Rules You can reorder rules to prioritize certain actions over others, ensuring that the most critical rules are applied first. This flexibility allows for a tailored approach to data ingestion, optimizing the system's performance and accuracy. 2. Create From Creating new ingestion rules from existing ones can save you a significant amount of time and offer the flexibility to incorporate additional logic or remove unnecessary elements. Effectively duplicating these rules ensures you can quickly adapt to new requirements, streamline operations, and maintain a high level of efficiency in managing your data ingestion process. 3. Delete Ingestion Rules Over time, certain rules may become obsolete or redundant as your organizational needs and security strategies evolve. It's important to note that each workspace is limited to a maximum of 25 ingestion rules. Having a clean and relevant set of rules ensures that your data ingestion process remains streamlined and efficient, minimizing unnecessary processing and potential conflicts. Deleting outdated or unnecessary rules allows for a more focused approach to threat detection and response. It reduces clutter, which can significantly enhance the performance. By regularly reviewing and purging obsolete rules, you maintain a high level of operational efficiency and ensure that only the most critical and up-to-date rules are in place. Conclusion By leveraging these pre-ingestion rules effectively, you can enhance the quality and reliability of the IOC’s ingested into Sentinel, leading to more accurate threat detection and an improved security posture for your organization.Introducing SOC Optimization Recommendations Based on Similar Organizations
One of the key challenges that security teams in modern SOCs regularly face is determining which new data sources to onboard and which detections to activate. This ongoing process takes time and requires constant evaluation of the organization’s assets and the value that the data brings to the SOC. "…determining which logs to ingest for better threat coverage is time-consuming and requires significant effort. I need to spend a long time identifying the appropriate logs..." Elie El Karkafi, Senior Solutions Architect, ampiO Solutions Today, we’re excited to announce the public preview of recommendations based on similar organizations - a first-of-its-kind capability for SOC optimizations. Recommendations based on similar organizations use peer-based insights to guide and accelerate your decision-making process. We believe that applying insights learned from the actions of organizations with similar profiles can provide great value. Recommendations based on similar organizations use advanced machine learning to suggest which data to ingest, based on organizations with similar ingestion patterns. The recommendations also highlight the security value you can gain by adding the data. They list out-of-the-box rules that are provided by Microsoft research, which you can activate to enhance your coverage. Use the new recommendations to swiftly pinpoint the next recommended data source for ingestion and determine the appropriate detections to apply. This can significantly reduce the time and costs typically associated with research or consulting external experts to gain the insights you need. Recommendations based on similar organizations are now available in the SOC optimization page, in both the Azure portal and the unified security operations platform: - unified security operations platform Use cases Let’s take a tour of the unified security operations platform, stepping into the shoes of a small tech company that benefited from recommendations based on similar organizations during its private preview phase. In the following image, the new recommendation identifies that the AADNonInteractiveUserSignInLogs table is used by organizations similar to theirs: Selecting View details button on the recommendation card allowed them to explore how other organizations use the recommended table. This includes insights into the percentage of organizations using the table for detection and investigation purposes. By selecting See details hyperlink, the SOC engineer was able to explore how coverage could be improved with respect to the MITRE ATT&CK framework, using Microsoft’s out-of-the box rules: By selecting Go to Content hub, the SOC engineer was able to view all the essential data connectors needed to start ingesting the recommended tables. This page also includes a detailed list of out of the box, recommended analytics rules, which can provide immediate value and enhanced protection for your environment: Finally, by following the recommendation, which uses the security practices of similar organizations as a benchmark, the tech company quickly ingested the AADNonInteractiveUserSignInLogs table and activated several recommended analytics rules. Overall, this resulted in improved security coverage, corresponding to the company's specific characteristics and needs. Feedback from private preview: “I think this is a great addition. Like being able to identify tables not being used, it is useful to understand what tables other organizations are utilizing which could reveal things that so far haven't been considered or missed...” Chris Hoard, infinigate.cloud "In my view, those free recommendations are always welcomed and we can justify cost saving and empowering SOC analysts (that we know are more and more difficult to find)." Cyrus Irandoust, IBM “These recommendations will help us to take a look at the left out stuffs” Emmanuel Karunya, KPMG “Nice overview and insights! Love the interface too - nice and easy overview!” Michael Morten Sonne, Microsoft MVP Q&A: Q1: Why don’t I see these recommendations? A: Not all workspaces are eligible for recommendations based on similar organizations. Workspaces only receive these recommendations if the machine learning model identifies significant similarities between your organization and others, and discovers tables that they have but you don’t. If no such similarities are identified, no extra recommendations are provided. You’re more likely to see these recommendations if your SOC is still in its onboarding process, rather than a more mature SOC. Q2: What makes an organization similar to mine? A: Similarity is determined based on ingestion trends, as well as your organization's industry and vertical, when available in our databases. Q3: Is any of my PII being used to make recommendations to other customers? A: No. The recommendations are generated using machine learning models that rely solely on Organizational Identifiable Information (OII) and system metadata. Customer log content is never accessed or analyzed, and no customer data, content, or End User Identifiable Information (EUII) is exposed during the analysis process. Microsoft prioritizes customer privacy and ensures that all processes comply with the highest standards of data protection. Looking forward Microsoft continues to use artificial intelligence and machine learning to help our customers defend against evolving threats and provide enhanced protection against cyberattacks. This ongoing innovation is a key part of SOC optimization’s commitment to help you maximize your value from your SIEM & XDR.
