Azure AD Privileged Identity Management member assigned

Set up the azure integration.

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.

The field @usr.id is the user that actioned the change, and the field @properties.targetResources.userPrincipalName is the user being assigned the administrative privileges.

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.
  1. 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.
