This detection rule monitors access attempts that violate Google Cloud Platform (GCP) VPC Service Controls, which are designed to enhance the security of GCP resources. When an access request is made that bypasses these controls—for instance, trying to perform operations on resources without required permissions or outside defined service perimeters—the rule flags the incident as a potential security violation. By tracking audit logs and identifying specific methods that breach these service controls, such as unauthorized requests to compute subnetworks or storage buckets, the rule allows organizations to respond proactively to potentially malicious activities. The rule operates at a medium severity level, necessitating prompt review to ascertain compliance, security risk, and any requisite remedial actions.
