Integrate RevealX 360 with Microsoft 365

ExtraHop RevealX

• You must have your RevealX 360 system connected to an ExtraHop sensor with firmware version 8.6 or later.
• The ExtraHop sensor must be licensed and configured to receive packets.

Microsoft

• You must have Microsoft 365 and Microsoft Graph API. Only the Microsoft Graph Global Service at https://graph.microsoft.com/ is supported for the integration.

  Note:

  To call Microsoft Graph, your app must acquire an access token from the Microsoft identity platform. The access token contains information about your app and the permissions it has for the resources and APIs available through Microsoft Graph. To create an access token, your app must be registered with the Microsoft identity platform and be authorized by either a user or an administrator to access the Microsoft Graph resources.

• You must have a registered application in Azure with the following permissions:

  API / Permissions Name	Type
  AuditLog.Read.All	Application
  AuditLog.Read.All	Delegated
  Directory.Read.All	Application
  Directory.Read.All	Delegated
  IdentityRiskEvent.Read.All	Application
  IdentityRiskEvent.Read.All	Delegated
  IdentityRiskyUser.Read.All	Application
  IdentityRiskyUser.Read.All	Delegated
  User.Read	Delegated

• Your Azure subscription must have following Standard Microsoft Entra ID features:
  • Directory Audit for Microsoft Entra ID
  • Microsoft Entra ID P1 or P2 License Endpoints

    P1 provides you with the list of service account sign-ins from the audit log. P2 includes P1 and additionally provides you with risk detections and risky users.

Dashboards

View metrics for Microsoft 365 events on the following built-in dashboards:

• Microsoft Entra ID, which displays event metrics such as transaction attempts, identity and password management, and user activity.
• Microsoft 365, which displays event metrics such as risky user activity, sign-in attempts, and risk detection.

Record types

View Microsoft 365 events in records by searching for the following record types:

• Azure Activity Log
• Microsoft 365 Directory Audit
• Microsoft 365 Risky Event
• Microsoft 365 Risky User
• Microsoft 365 Sign-ins

Detections

View Microsoft 365 risk events that are retrieved through the Microsoft Graph API and displayed in the following RevealX detections:

• Risky User Activities
• Suspicious Sign-ins

The following examples describe some of the risky user events and suspicious actions that are detected through the integration service.

Impossible Travel

A user signs in from two geographically different locations. The two sign-in events occurred within a shorter time than it would take for the user to travel between locations. This activity might indicate that an attacker signed in with user credentials.

Password Spray

A password spray attack is a type of brute force attack, where numerous sign-ins for multiple usernames and common passwords are attempted to gain unauthorized access to an account.

Suspicious Inbox Forwarding

The Microsoft Cloud App Security (MCAS) service identifies suspicious email forwarding rules, such as a user-created inbox rule that forwards a copy of all emails to an external address.

Admin Confirmed User Compromised

An administrator selected Confirm user compromised in the Risky Users UI or riskyUsers API of the Identity Protection service.
