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.Information leakage is the intentional or unintentional release of information to an untrusted environment from electromagnetic signals emanations. Security categories or classifications of information systems (with respect to confidentiality) and organizational security policies guide the selection of security controls employed to protect systems against information leakage due to electromagnetic signals emanations. The 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. The TEMPEST/01-13 requires the facility housing the secure VC equipment (i.e., the secure conference room) must meet the TEMPEST requirements for such rooms. The appropriate and required separations between RED and BLACK equipment and cables must be met. This includes cable routing inside equipment cabinets. Depending on the TEMPEST ZONE, the separation requirements are:- Minimum equipment separation - 50 cm or 1 m- Minimum cable separation - 5 cm or 15 cmNational policy requires that systems and facilities processing NSI must be reviewed by a Certified TEMPEST Technical Authority (CTTA) to achieve TEMPEST security. The CTTA may require separate power sources for RED equipment and BLACK equipment.

If the Voice Video system does not support conferences on multiple networks having different classification levels, this is not applicable. Review the architecture in the Voice Video SSP for the system. Confirm the VC system supporting conferences on multiple networks having different classification levels must maintain isolation between the networks to which it connects by implementing separation of equipment and cabling between the various networks having differing classification levels in accordance with CNSSAM TEMPEST/01-13, RED/BLACK Installation Guidance. Verify, based on the TEMPEST ZONE in the CNSSAM TEMPEST/01-13, RED/BLACK Installation Guidance, whether the required separations between RED and BLACK equipment and cables have been met. This includes cable routing inside equipment cabinets. Depending on the TEMPEST ZONE, the separation requirements are: - Minimum equipment separation - 50 cm or 1 m - Minimum cable separation - 5 cm or 15 cm If a CTTA has reviewed the system's installation and provided a favorable report or certification, this is not a finding. If the cables or equipment are closer than the minimum cable and equipment separation distances, this is a finding.
