GCP Virtual Private Cloud Route Creation
editGCP Virtual Private Cloud Route Creation
editIdentifies when a Virtual Private Cloud (VPC) route is created in Google Cloud Platform (GCP). Google Cloud routes define the paths that network traffic takes from a virtual machine (VM) instance to other destinations. These destinations can be inside a Google VPC network or outside it. An adversary may create a route in order to impact the flow of network traffic in their target’s cloud environment.
