Title

The required dual homed DISN Core or NIPRNet access circuits must follow geographically diverse paths from the CER(s) along the entire route to the geographically diverse SDNs.

Description

<VulnDiscussion>One way to provide the greatest reliability and availability for DISN services is to provide redundancy in the network pathways between the customer site and the redundant DISN SDNs. The DISN core network is designed to be highly reliable and available in support of the DOD mission. The most vulnerable part of the network is the access circuit from the enclave to the core and the path it takes from the SDN to the customer's site. Therefore, redundant access circuits should be p...

Ensure dual-homed DISN Core or NIPRNet access circuits follow geographically diverse paths from the CER(s) along the entire route to the geographically diverse SDNs. Ensure each circuit uses different facilities such as cables, demarks, and digital cross connects in geographically diverse locations. Ensure geographic and facilities information is maintained on-site and off-site. Ensure the paths taken by the access circuits remain significantly separate along their entire length so that a single point of failure is not created.
