Scanning in GCP Environments

In this section, let us take a look at some common use cases for scanning a GCP environment.

Networking Basics

To start with, let us get familiar with a few terms in networking basics.

VPC Networks

A Virtual Private Cloud (VPC) network provides networking functionality for Google Compute Engine Virtual Machine (VM ) instances. This pretty much resembles a traditional network in your own data center, except that it is virtualized within Google cloud. Without a VPC Network, you cannot create VM instances. It is a global resource; but an organization may want to separate their deployment environments, and so, they create VPCs for isolation purposes.

VPC Peering

This networking connection between two VPCs enables you to connect VM instances hosted in separate VPC networks and route traffic between them.

Subnets

These are one or more useful IP range partitions in each VPC network. It is a regional resource.
