GCP Firewall Rule Creation

edit

Identifies when a firewall rule is created in Google Cloud Platform (GCP) for Virtual Private Cloud (VPC) or App Engine. These firewall rules can be configured to allow or deny connections to or from virtual machine (VM) instances or specific applications. An adversary may create a new firewall rule in order to weaken their target’s security controls and allow more permissive ingress or egress traffic flows for their benefit.
