Description
It will be assumed that any peripheral other than a keyboard, video monitor, or mouse attached to a KVM switch is intended to be used regardless of the current configuration of the KVM switch. This peripheral can contain persistent memory that can be used to move data between ISs of different classification levels compromising either the data that was moved and the IS to which the data was moved. When the KVM switch is attached to ISs of different classification levels, the ISSO, the SA, and the user will ensure no peripherals other than the keyboard, video, or mouse is connected to the KVM.

Check Text ( C-2683r2_chk )
The reviewer will view the KVM switch, used in an environment where it is attached to ISs of different classification levels, to verify no peripherals other than the keyboard, video monitor, and mouse are attached. If any other peripherals are attached, this is a finding.

Fix Text (F-6298r2_fix)
Remove the unauthorized peripheral and block the port it is attached to with tamper resistant/evident seals. Tamper resistant/evident seals are available from Protective Technologies: ptproducts@radium.ncsc.mil.
