The detection rule "GCP Workforce Pool Created or Updated" is designed to monitor changes to Google Cloud Platform (GCP) Workforce Pools by analyzing GCP audit logs. It specifies two key operations: creation and updating of workforce pools, both of which can signify potential account manipulation or privilege escalation activities. This rule is crucial, as unauthorized changes to workforce pools may allow adversaries to persist within the environment or gain elevated privileges. To ensure appropriate tracking, the rule is flagged as high severity and aims to detect any unexpected creation or modification of workforce pools. The defined tests will confirm whether these alterations were anticipated or unauthorized, providing a proactive defense against malicious actions within GCP.
