Title

The Voice Video Endpoint used for unclassified communication within a Sensitive Compartmented Information Facility (SCIF) or Special Access Program Facility (SAPF) must be National Telecommunications Security Working Group (NTSWG)-approved device in accordance with the Committee on National Security Systems Instruction (CNSSI) 5000. (Cat II impact)

Discussion

Configuring the Voice Video Endpoint to implement CNSSI 5000 for unclassified communication within SCIFs and SAPF ensures compliance with federal standards and establishes a common security baseline across DoD that reflects the most restrictive security posture consistent with operational requirements. Voice Video Endpoints may transmit classified conversations over unclassified networks. Voice Video Endpoint microphones, speakers, and supporting electronics may pick up conversation audio within the area and conduct it over the network connection, even when the endpoint is on-hook, powered or not. The Technical Surveillance Counter-Measures (TSCM) program protects sensitive government information, to include classified information, through the establishment of on-hook audio security standards. Voice Video Endpoints certified by NTSWG are modified to prevent this behavior, or limit it to within acceptable levels.

Check Content

If the Voice Video Endpoint is not used for unclassified communication within a SCIF or SAPF, this check procedure is Not Applicable. Verify the Voice Video Endpoint used for unclassified communication within a SCIF or SAPF is an NTSWG-approved device meeting the requirements outlined in CNSSI 5000. Confirm a valid NTSWG certification seal is affixed to the Voice Video Endpoint with no indication of tampering. If the Voice Video Endpoint is not an NTSWG-approved device with an affixed certification seal, this is a finding. If the Voice Video Endpoint reveals any evidence of tampering, or the seal is broken, cut, or in any way tampered with, this is a finding.

Fix Text

Replace the Voice Video Endpoint used for unclassified communication within a SCIF or SAPF with an NTSWG-approved device meeting the requirements outlined in CNSSI 5000. Confirm a valid NTSWG certification seal is affixed to the Voice Video Endpoint with no indication of tampering. The list of NTSWG-approved instruments is available on the National Counterintelligence and Security Center website using the URL below, then clicking on "TSG-6-Approved Telephones (PDF)" link to download the list: https://www.dni.gov/index.php/ncsc-what-we-do/ncsc-physical-security-mission The manufacturer places the certification seals prior to shipment, and if the seal is broken, cut, or in any way tampered with, it is no longer considered valid.
