The GCP Privileged Operation rule is designed to monitor and identify potentially unauthorized privileged operations within Google Cloud Platform (GCP) that may indicate privilege escalation attempts. The rule specifically looks for activity related to the modification of IAM policies, particularly following the creation of tag bindings. Upon detection of such operations, it assesses whether the user has legitimate business justification for performing these actions. If the operations appear unauthorized, the rule recommends revoking the recent tag bindings and conducting a review of IAM policies to ensure proper access controls are upheld.
