This detection rule monitors for the creation, patching, update, or deletion of RoleBindings and ClusterRoleBindings within a Google Cloud Kubernetes environment. RoleBindings control access to Kubernetes resources, and sudden changes to them may indicate unauthorized access or adjustments to user permissions that can compromise cluster security. The rule captures specific methods associated with these actions as they are logged in GCP (Google Cloud Platform) audit logs. It is essential to ensure that these modifications originate from legitimate administrative actions, as they can also be performed by system administrators. False positives may occur in environments with known behavioral patterns, and careful investigation is necessary when changes are initiated by unfamiliar users or identities. This rule aids in enforcing security policies and maintaining continuous monitoring of RBAC (Role-Based Access Control) changes in Kubernetes, thereby improving the overall security posture of the cloud environment.
