Suspicious login alert rule is configured

rules_suspicious_login_alert_configured
Service: rulesSeverity: low
OfficialBuilt-inVerified
Categories:loggingidentity-access
Resource Type:NotDefined

The Suspicious login system-defined alert rule should be enabled with alerts sent to the alert center, email notifications turned on, recipients set to all super administrators, and severity set to Low or higher. This ensures administrators are notified when Google detects a sign-in attempt that does not match a user's normal behavior.

Risk

Without this alert enabled, administrators will not be notified of suspicious login attempts such as sign-ins from unusual locations. This could indicate an active attack using previously obtained credentials.
