Vulnerability discussion

The information security architecture at the individual information system level must be consistent with and complement the more global, organization-wide information security architecture that is integral to and developed as part of the enterprise architecture. The information security architecture includes an architectural description, the placement/allocation of security functionality (including security controls), security-related information for external interfaces, information being exchanged across the interfaces, and the protection mechanisms associated with each interface.In addition, the security architecture can include other important security-related information, for example, user roles and access privileges assigned to each role; unique security requirements; the types of information processed, stored, and transmitted by the information system; restoration priorities of information and information system services; and any other specific protection needs.Committee on National Security Systems Advisory Memorandum (CNSSAM) TEMPEST/01-13, RED/BLACK Installation Guidance, provides criteria for the installation of electronic equipment, cabling, and facility support for the processing of secure information. National policy requires that systems and facilities processing NSI must be reviewed by a Certified TEMPEST Technical Authority (CTTA) to achieve TEMPEST security. The RED/BLACK guidance contained in TEMPEST/01-13 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.

Check content

If the Voice Video system does not implement a single CODEC supporting conferences on multiple networks having different classification levels, this is not applicable. Review the Voice Video SSP for the system. Confirm the VC system A/B, A/B/C, or A/B/C/D switches are TEMPEST certified. Review TEMPEST certification documentation provided by a CTTA or the vendor to validate that the switch is TEMPEST certified. If the VC system A/B, A/B/C, or A/B/C/D switch is not TEMPEST certified, or satisfactory documentation is not provided, this is a finding.

Fix text

Obtain and install a TEMPEST-certified A/B, A/B/C, or A/B/C/D switch. Document the solution in the Voice Video SSP for this system.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.
