What it detects

This rule identifies Google Workspace admin events where an application setting beginning with ContextAwareAccess is modified via the admin.googleapis.com CHANGE_APPLICATION_SETTING activity. Changing these access levels can reduce enforcement controls and help an attacker broaden access to Workspace resources. It relies on Google Workspace administrative audit telemetry capturing the event service, event name, and setting_name prefix.
