GCP Pub/Sub Topic Deletionedit
Identifies the deletion of a topic in Google Cloud Platform (GCP). In GCP, the publisher-subscriber relationship (Pub/Sub) is an asynchronous messaging service that decouples event-producing and event-processing services. A publisher application creates and sends messages to a topic. Deleting a topic can interrupt message flow in the Pub/Sub pipeline.

Potential false positivesedit
Topic 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. Topic deletions by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
