Title

An IP-based VTC system implementing a single CODEC that supports conferences on multiple networks with different classification levels must be implemented in such a way that configuration information for a network having a higher classification level is not disclosed to a network having a lower classification level.

Description

<VulnDiscussion>Connecting the CODEC to a network while it is being reconfigured could lead to the disclosure of sensitive configuration information for a network having a higher classification level to a network having a lower classification level. Ideally, the CODEC will be disconnected from any network while it is being reconfigured. However, the requirement can be met by using a procedure that purges the configuration for the currently connected network, power cycling the CODEC as required...

Fix Text (Documentation Requirement)

Do one of the following: - Architect, implement, and configure the system so the A/B, A/B/C, or A/B/C/D switch connects the CODEC to an unused switch position while it is being reconfigured during transition from one network to another. - Architect, implement, and configure the system so the CODEC configuration is purged before it is switched to the next network, the CODEC is power cycled for the required time period as the A/B, A/B/C, or A/B/C/D switch connects the CODEC to the next network, and then the CODEC is reconfigured for that network. - If a manual switching procedure is used, physically disconnect the CODEC from any network while it is reconfigured for the next network.
