This rule detects modifications or deletions made to DNS zones within Google Cloud Platform (GCP). Utilizing audit logs from Google Cloud, it specifically triggers when any of the following methods are called: `Dns.ManagedZones.Delete`, `Dns.ManagedZones.Update`, or `Dns.ManagedZones.Patch`. These operations indicate potentially unauthorized or malicious activities affecting DNS configurations, which can lead to significant disruptions in service availability or outages if an attacker successfully alters or removes DNS records. Monitoring these actions is crucial for maintaining the integrity and operational stability of cloud-hosted services that rely on DNS for routing traffic. The rule is currently in test status and is authored by Austin Songer with references provided for deeper insights into managed DNS zones in GCP.
