The implementation of an IP-based VTC system that supports conferences on multiple networks with different classification levels must maintain isolation between the networks to which it connects by implementing separation of equipment and cabling between the various networks with differing classification levels in accordance with CNSSAM TEMPEST/01-13, RED/BLACK Installation Guidance.

Medium Severity
<VulnDiscussion>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 that the facility housing the secure VTC 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 cm.
National 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.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
