STIGQter: STIG Summary: Enterprise Voice, Video, and Messaging Policy Security Requirements Guide Version: 1 Release: 4 Benchmark Date: 05 Jan 2026:

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.

Fix Recommendation

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.

Check Contents

Inspect the documentation for the pathways taken by the access circuits to determine compliance with the requirement. Obtain the pathway documentation for the facilities on-site.

Additionally, obtain information from the DISN core PMO and/or local carrier of the access circuits for the pathways off-site.

Verify the ISSO maintains a copy for future inspections. Changes to the pathways must also be recorded and maintained.

If the required dual-homed circuits follow the same path or are close enough anywhere along their length to be damaged by a single event, this is a finding.
