This rule is designed to detect modifications and deletions of Google Cloud Platform (GCP) Cloud Storage buckets. The detection mechanism focuses on the audit logs generated by GCP, specifically the 'GCP.AuditLog' type. These logs record activities such as updating bucket configurations or deleting buckets. The rule uses specific event attributes such as the method name of 'storage.buckets.update' and monitors the user's actions across defined time frames. When such activities are logged, the rule generates alerts if they exceed a specified threshold, indicating potential unauthorized changes or operational issues. This rule is essential for maintaining oversight and control over cloud storage management, ensuring that any modifications or deletions are intentional and compliant with established organizational policies.
