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.
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.

Installing the Microsoft Graph Security app
This section has instructions for installing the Microsoft Graph Security app for Sumo Logic.
To install the app:
- From the Sumo Logic nav, select App Catalog.
- Search for and select your app.
- (Optional) To see a preview of the dashboards included with the app, scroll down to the Dashboard Preview section.
- If the app has multiple versions - not all apps do - select the version of the service you're using, then click Add Integration.
- On the next configuration page, under Select Data Source for your App, complete the following fields:
- Data Source. Select one of the following options:
- Choose Source Category and select a source category from the list; or
- Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. For example,
_sourceCategory=MyCategory.
- Folder Name. You can retain the existing name or enter a custom name of your choice for the app.
- All Folders (optional). Default location is the Personal folder in your Library. If desired, you can choose a different location and/or click New Folder to add it to a new folder.
- Data Source. Select one of the following options:
- Click Next.
- You'll see a dialog confirming that the app was installed successfully.
Once an app is installed, it will appear in your Personal folder, or other folder that you specified. From here, you can share it with your organization.
Panels will start to fill automatically. It's important to note that each panel slowly fills with data matching the time range query and received since the panel was created. Results won't be available immediately, but within 20 minutes, you'll see full graphs and maps.
Viewing Microsoft Graph Security dashboards
All dashboards have a set of filters that you can apply to the entire dashboard, as shown in the following example. Click the funnel icon in the top dashboard menu bar to display a scrollable list of filters that are applied across the entire dashboard.
You can use filters to drill down and examine the data on a granular level. Filters include client country, client device type, client IP, client request host, client request URI, client request user agent, edge response status, origin IP, and origin response status.
Each panel has a set of filters that are applied to the results for that panel only, as shown in the following example. Click the funnel icon in the top panel menu bar to display a list of panel-specific filters.
