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.

Set up collection

Follow the instructions for setting up the 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.

To install the app, do the following:

1. From the Sumo Logic navigation, select App Catalog.
2. In the Search Apps field, search for and then select your app.
   Optionally, you can scroll down to preview the dashboards included with the app.
3. To install the app, click Install App.
4. Click Next in the Setup Data section.
5. In the Configure section of the respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category, and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Your app will be installed in the Installed Apps folder and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, updating with full graphs and charts over time.

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 Filter 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.
