GCP Pub/Sub Subscription Creation

GCP Pub/Sub Subscription Creation

edit

Identifies the creation of a subscription 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 subscription is a named resource representing the stream of messages to be delivered to the subscribing application.

Potential false positives

edit

Subscription creations 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. Subscription creations by unfamiliar users or hosts should be investigated. If known behavior is causing false positives, it can be exempted from the rule.
