This rule is designed to detect modifications to Google Cloud service accounts, which are critical components in managing access to resources within the Google Cloud Platform (GCP). The detection criteria include specific API methods that indicate changes to service accounts, such as creating, updating, enabling, or undeleting them. These operations can significantly impact security if performed maliciously or by unauthorized users. The rule utilizes logs from GCP's audit service, filtering for operations related to service account modification. Security teams should monitor alerts generated by this rule to ensure that only legitimate modifications are occurring and to detect potentially malicious activities that may compromise cloud-based resources.
