Goal

Detect whenever a user assigns an administrative role in Azure Privileged Identity Management (PIM).

Strategy

Monitor Azure Active Directory and generate a signal when a user assigns an administrative role to a PIM member.

Triage and response

1. Determine if {{@usr.id}} should have assigned the administrative role.
2. If the API call was not made by the user:

• Rotate user credentials.
• Determine what other API calls were made by the user.
• Begin your organization’s incident response (IR) process and investigate.

3. If the API call was made legitimately:

• Determine if {{@usr.id}} was authorized to make the change.
• Follow Microsoft’s best practices where possible to ensure the user was assigned the correct level of privileges for their function.
