The Video Conferencing (VC) system implementing a single CODEC supporting conferences on multiple networks having different classification levels (i.e., unclassified, SECRET, TOP SECRET, TS-SCI) must support and document Periods Processing by connecting the CODEC to one network at a time, matching the classification level of the session to the classification level of the network.

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.Connecting to networks of different classifications simultaneously incurs the risk of data from a higher classification being released to a network of a lower classification, referred to as a "spill". It is imperative that networks of differing classification levels or with differing handling caveats not be interconnected at any time. Separation in a multinetwork VC system is maintained by the use of an A/B, A/B/C, or A/B/C/D switch that meets requirements for channel isolation or by manual connection of the CODEC to one network at a time.

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 architecture has an approved A/B, A/B/C, or A/B/C/D switch present and properly cabled. Alternately, validate that the VC CODEC is manually connected to one network at a time through the use of a single patch cord. Periods Processing must connect the CODEC to one network at a time, matching the classification level of the session to the classification level of the network. If Periods Processing uses an approved A/B, A/B/C, or A/B/C/D switch properly cabled to connect the CODEC to one network at a time, matching the classification level of the session to the classification level of the network, this is not a finding. If Periods Processing uses a single patch cord to connect the CODEC to one network at a time, matching the classification level of the session to the classification level of the network, this is not a finding. If neither is in place, this is a finding.

Obtain and install an approved A/B, A/B/C, or A/B/C/D switch. Alternately, manually connect the VC CODEC to one network at a time through the use of a single patch cord. Periods Processing must connect the CODEC to one network at a time, matching the classification level of the session to the classification level of the network. Document the solution in the Voice Video SSP for this system.
