GCP Logging Sink Deletion
Identifies a Logging sink deletion in Google Cloud Platform (GCP). Every time a log entry arrives, Logging compares the log entry to the sinks in that resource. Each sink whose filter matches the log entry writes a copy of the log entry to the sink's export destination. An adversary may delete a Logging sink to evade detection.
Detection Logic
data_stream.dataset:gcp.audit and event.action:google.logging.v*.ConfigServiceV*.DeleteSink and event.outcome:successFalse Positives
- ⚠ Logging sink deletions may be done by a system or network administrator. Verify whether the user email, resource name, and/or hostname should be making changes in your environment. Logging sink deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
