Description
National Security Telecommunications and Information Systems Security Advisory Memorandum (NSTISSAM) TEMPEST-2-95 and other similar documents provide the requirements and installation guidelines for systems and facilities processing National Security Information (NSI). A Certified TEMPEST Technical Authority (CTTA) is a certified individual who has been appointed by a U.S. Government department or agency to fulfill CTTA responsibilities. National policy requires that certain systems and facilities that process NSI must be reviewed by a CTTA. The CTTA will consider a variety of methods that can be applied to the system/facility to achieve TEMPEST security. The RED/BLACK guidance contained in TEMPEST-2-95 will be considered by the CTTA along with other measures (e.g., TEMPEST Zoning, TEMPEST suppressed equipment and shielding) to determine the most cost-effective countermeasures to achieve TEMPEST security. Only those RED/BLACK criteria specifically identified by the CTTA will be implemented. DISN Video Services (DVS) maintains a list of A/B switches and dial isolators that have been TEMPEST certified to meet the above requirements at http://disa.mil/Services/Network-Services/Video/~/media/Files/DISA/Services/DVS/red_black_peripherals.xls.

Review the documentation to verify whether the A/B, A/B/C, or A/B/C/D switch is TEMPEST certified. DISN Video Services (DVS) maintains a list of A/B, A/B/C, or A/B/C/D switches that have been TEMPEST certified to meet the above requirements at http://disa.mil/Services/Network-Services/Video/~/media/Files/DISA/Services/DVS/red_black_peripherals.xls. Alternately, review TEMPEST certification documentation provided by a CTTA or the vendor. If the A/B, A/B/C, or A/B/C/D switch is not on the list, or satisfactory documentation is not provided, this is a finding.
