This rule detects operations related to the creation or updating of Google Cloud Platform (GCP) Workload Identity Pools, which are critical for managing identities in a cloud environment. The detection is triggered by audit logs generated during the creation or update of these pools. Adversaries may exploit the ability to create or modify workload identity pools as part of a privilege escalation attack or account manipulation. The rule analyzes GCP audit logs for specific permissions being granted, such as `iam.workloadIdentityPools.create` or `iam.workloadIdentityPoolProviders.update`, indicating that an unauthorized or unexpected change has occurred. The rule aims to provide alerts for any modification of identity pools that could lead to insecure configurations or unauthorized access privileges if not authorized. The detection leverages logs from GCP, specifically the Cloud Audit Log service, to identify changes to workload identity pools and its providers, ensuring appropriate monitoring of critical identity management components.
