Multi-workspace management in Azure Sentinel allows analysts to aggregate data from various Azure workspaces, other clouds, and on-premises solutions into a central pane for security analysis. This capacity is critical for organizations that operate across multiple geographical locations, maintain separate workspaces for different departments, or must adhere to data residency requirements.
Analysts can use multi-workspace queries to run searches across several workspaces from within the Azure Sentinel portal. This facilitates a comprehensive view of an organization’s security posture.
To set up cross-workspace queries in Azure Sentinel, analysts must have the appropriate permissions across all the workspaces they intend to query. Here are the steps involved:
Sample Query:
union workspace(“WorkspaceID1”).SecurityEvent, workspace(“WorkspaceID2”).SecurityEvent
| where TimeGenerated > ago(1d)
| where AccountType == ‘User’
| summarize Count = count() by Account
| sort by Count desc
This query gathers security events from two workspaces for the past 24 hours and summarizes the data by user accounts, sorting the outcome based on the count of events.
When an incident occurs, it is pivotal to perform a holistic investigation. The following steps are often taken:
When comparing incidents across various workspaces, creating a comparative analysis can be instrumental in determining patterns and anomalies.
Feature | Workspace A | Workspace B | Notes |
---|---|---|---|
Number of Incidents | 50 | 30 | Comparison of incident frequency |
Incident Severity | High | Medium | – |
Affected Resources | VMs, Databases | Storage Accounts | Type of resources impacted |
Alert Types | Malware, DDoS | Phishing, Ransomware | Predominant alert categories |
Response Time | 2 hours | 30 minutes | Response efficiency |
Geographic Location | North America | Europe | Physical location of the workspace |
Multi-workspace incident investigation faces complexity. Analysts must take into account the differences in data types, formats, and volume. Moreover, different workspaces may have different compliance and privacy requirements dictating how data is handled.
To address these challenges, it is important to have a centralized governance model, ensure team members are adequately trained, and have a standard operating procedure for responding to multi-workspace incidents.
In summary, investigating incidents across multiple workspaces demands an organized approach, leveraging Azure Sentinel’s multi-workspace capabilities, and ensuring compliance with incident response protocols. By mastering cross-workspace investigations, security analysts become empowered to better protect their organization’s assets across the entire digital estate.
Correct Answer: True
Explanation: Azure Sentinel can be used to correlate alerts across different workspaces by using cross-workspace queries, enabling comprehensive investigations spanning multiple workspaces.
Correct Answer: C) Azure Sentinel
Explanation: Azure Sentinel is used for managing and investigating security events across multiple workspaces, as it allows for the collection, detection, investigation, and response to security events within a single solution.
Correct Answer: True
Explanation: Microsoft Defender for Endpoint can be integrated with Azure Sentinel, providing additional telemetry data that can be leveraged when investigating incidents across multiple workspaces.
Correct Answer: A) Isolate the incident to a single workspace
Explanation: When investigating a multi-workspace security incident, it is important to consider all affected workspaces rather than isolating the incident to a single workspace, in order to gain a full understanding of the scope and impacts.
Correct Answer: False
Explanation: Sharing information between workspaces is often necessary when investigating multi-workspace incidents to ensure that all relevant data is considered in the investigation process.
Correct Answer: True
Explanation: Azure Sentinel Notebooks enable analysts to investigate incidents using machine learning, advanced analytics, and visualization techniques within an interactive coding and data manipulation environment.
Correct Answer: D) Azure Lighthouse
Explanation: Azure Lighthouse enables service providers and enterprise IT teams to manage, view, and query data across multiple Azure workspaces centrally.
Correct Answer: False
Explanation: Azure Sentinel Incidents can contain alerts from multiple data sources as well as from multiple workspaces, as long as cross-workspace queries are configured to correlate data.
Correct Answer: B) Easier correlation of events across workspaces
Explanation: A common schema standardizes the data format and makes it easier to correlate events across workspaces, thus facilitating more effective and efficient investigations.
Correct Answer: C) Centralizing visibility and control
Explanation: Centralizing visibility and control is essential for effective multi-workspace incident investigation, as it gives the security operations team a unified view of the threat landscape and simplifies managing security across different environments.
Multi-workspace view is a feature that allows users to investigate incidents across multiple Azure Sentinel workspaces from a single pane of glass.
Multi-workspace view can be accessed by selecting the “Multi-Workspace” option in the top navigation menu in Microsoft Sentinel.
Multi-workspace view makes it easier to investigate incidents that span multiple workspaces by providing a single location to view and analyze data from all relevant workspaces.
No, multi-workspace view only provides data for incidents that occur after the feature has been enabled.
The multi-workspace view can be customized by filtering incidents by workspace, severity, status, and other criteria.
Yes, you can modify incident details and take action on incidents from the multi-workspace view just like you can in the regular incident view.
Yes, you can share the multi-workspace view with other users or teams by creating a custom bookmark that includes the multi-workspace view URL.
Multi-workspace view removes duplicate data from multiple workspaces to prevent the same incident from appearing multiple times.
Yes, you can create custom queries in multi-workspace view to filter and analyze incident data.
No, multi-workspace view is a free feature included with Azure Sentinel.
