services / Google Cloud / Compute Engine network endpoint groups

Manage network endpoint groups (NEGs) for Google Cloud load balancers.

Multiple organizational functions may often reside within Compute Engine. However, abuse of network-endpoint rules requires leveraging additional risks in VM / VPC configuration, such as sensitive data or access broadcast on open VPC ports.

With a NEG on an already accessible network, can be used to connect to sensitive backend services. Can be combined with `create` to broaden attack surface.

Risks
