Goal

Detect when a Google Workspace user unenrolls from Google’s Advanced Protection.

Strategy

Monitor Google Workspace logs to detect when a user unenrolls from Google’s Advanced Protection. An attacker who has already gained initial access may unenroll from Advanced Protection to degrade security controls.

Triage and response

  1. Check for other signals and logs generated by the impacted user {{@usr.email}}, and look for deviations in the following properties:
    • Application
    • Device
    • Geolocation
    • IP address
  2. Reach out to the user {{@usr.email}} to confirm if they recognize the activity.
  3. If the activity is not legitimate, block the user from signing in and begin your Incident Response process.
