This rule detects the deletion of access policies associated with Google Cloud Platform (GCP) resources, which could indicate an attempt by an adversary to escalate their privileges by removing restrictions on access. Access policies are critical as they control the security and accessibility of cloud resources; their deletion can expose resources to unauthorized access. The rule looks for specific permission deletions in the audit logs, signaling potential malicious activity. It exists in a GCP environment, triggering alerts when it identifies any of the defined access policy delete actions alongside successful authorization checks. Notably, administrative activities that may involve policy changes could be falsely flagged, so monitoring should be contextual aware.
