This question aligns with CHFI v11 objectives underCloud Forensics, particularlyGoogle Cloud audit log analysis and authentication event investigation. In Google Cloud Platform (GCP), authentication-related events—such as login attempts, failed authentications, suspicious access behavior, and account lockouts—are handled by theGoogle Login API service. CHFI v11 emphasizes that when investigators are examining suspected credential compromise or password leaks, they must focus onauthentication and identity-related logsrather than general administrative or configuration logs.

The filter

protopayload.resource.labels.service="login.googleapis.com"

targets audit log entries generated by the login service, which records successful and failed login attempts, abnormal authentication behavior, and security enforcement actions such as temporary account lockouts caused by repeated failed logins. These events are critical indicators when determining whether a password leak resulted in account disabling.

The other options are less suitable: admin.googleapis.com focuses on administrative actions, the activity log name is broad and not specific to authentication failures, and metadata parameter filters do not directly isolate login-related events. Therefore, consistent with CHFI v11 cloud forensic methodology, filtering logs by thelogin.googleapis.comservice is the most effective way to identify whether a password leak caused a user account to be disabled.
