Microsoft Graph Security
The Sumo Logic App for Microsoft Graph Security enables you to identify security threats by analysing 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.
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.

Set up collection
Follow the instructions for setting up Cloud to Cloud Integration for Microsoft Graph Security source and use the same source category while installing the app.
Installing the Microsoft Graph Security app
This section has instructions for installing the Microsoft Graph Security app for Sumo Logic and descriptions of each of the dashboards.
Locate and install the app you need from the App Catalog. If you want to see a preview of the dashboards included with the app before installing, click Preview Dashboards.
- From the App Catalog, search for the app and select it.
- Select Add Integration button to install the app.
- Configure Microsoft Graph Security app using the steps described in the Microsoft Graph Security Cloud-to-Cloud Source. If you already have set up your data, skip this step by clicking on Next.
- Complete the following fields:
- Data Source. Select either of these options for the data source:
- Choose Source Category and then choose a source category from the list.
- Select Enter a Custom Data Filter and type in a custom source category that starts with an underscore. For Example,
_sourceCategory=MyCategory.
- Folder Name. You can retain the existing name, or enter a name of your choice for the app.
- Select the Location in Library (the default is the Personal folder in the library), or click New Folder to add a new folder.
- Data Source. Select either of these options for the data source:
- Click Next.
Once an app is installed, it will appear in your Personal folder, or other folder that you specified. You can share it with your organization.
The panels will begin to fill automatically. It's worth noting that each panel gradually fills with data that matches the time range query and has been received since the panel was created. The results will not be available right away, but with some patience, you will be able to view 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.
