Description
The back plate of some 4 or 8 port CYBEX/AVOCENT KVM devices provides a physical connection between adjacent ports. Therefore failure to provide for physical port separation between SIPRNet (classified devices) and NIPRNet (unclassified devices) when using CYBEX/AVOCENT KVM devices can result in the loss or compromise of classified information.

Check Text ( C-39804r2_chk )
Validate the correct configuration of CYBEX/Avocent 4 or 8 port KVMs IAW DSAWG guidance. This includes physical port separation between SIPRNet and NIPRNet (high & low) connections. Because of the internal physical configuration of the CYBEX boxes, only like classification levels may be connected to adjacent ports. TACTICAL ENVIRONMENT: The check is applicable where KVM devices are in use.

Fix Text (F-35002r2_fix)
1. CYBEX/Avocent 4 or 8 port KVMs used for switching devices between the SIPRNet and NIPRNet (or any switching between SIPRNet and any other unclassified network devices) must be correctly configured IAW DSAWG guidance. 2. Correct configuration must include physical port separation between SIPRNet and NIPRNet (high & low) (or any switching between SIPRNet and any other unclassified network devices) connections. 3. Because of the internal physical configuration of the CYBEX/Avocent box back plates, only like classification levels may be connected to adjacent ports.
