Microsoft Graph Security V1

The Sumo Logic App for Microsoft Graph Security V1 enables you to identify security threats by analyzing alert logs and helps you to improve web security posture, proactively detect and mitigate potential security risks, and improve compliance with security policies and regulations.

warning

This version of the app uses alerts from Microsoft Graph API (https://learn.microsoft.com/en-us/graph/api/alert-list?view=graph-rest-1.0&tabs=http) and continues to be supported for existing customers who are bringing in alerts from that source. If you are setting up a new cloud-to-cloud source, it will use API V2 (https://learn.microsoft.com/en-us/graph/api/security-list-alerts_v2?view=graph-rest-1.0&tabs=http) which is covered by the Microsoft Graph Security V2 app.

Key features of the Microsoft Graph Security app include:

• Detect and mitigate potential ransomware attacks.
• Monitor endpoint security and identify potential threats.
• High-level overview of the organizational security posture, including metrics such as the number of alerts, alert severity, and status.
• Allows security teams to identify potential threats and take appropriate action based on the trends and patterns of security alerts over time.

Log types

This app uses Sumo Logic’s Microsoft Graph Security Source to collect Alerts from Microsoft Graph Security.

Viewing Microsoft Graph Security dashboards

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
