| Validate the network diagram by correlating the information with all routers, multi-layer switches, and firewall configurations.
Validate all subnets have been documented accordingly.
Validate any connectivity documented on the diagram by physically examining the cable connections for the downstream and upstream links, as well as connections for major network components (Routers, Switches, Firewalls, IDS/IPS, etc.).
If the site has not maintained network topology diagrams for the enclave, this is a finding.
