From Keyboard, Video, Mouse Switch Security STIG
Part of KVM Desktop Backgrounds
Associated with IA controls: ECML-1
Without the banners to identify the IS that the KVM switch is currently active on, the user could enter a command to the wrong IS and create a denial of service or the user could inter data into the wrong system creating either a security incident (data entered to a system of the wrong classification) or a compromise of sensitive data.
The reviewer will view the desktop backgrounds of the ISs attached to the KVM switch and verify that they are labeled as required. The desktop backgrounds will display classification banners at the top and bottom of the screen. These banners will state the overall classification level of the IS in large bold type. These banners will have a solid background color assigned using the following scheme: Yellow for Special Compartmented Information (SCI). Orange for Tope Secret (TS). Red for Secret. Blue for Confidential. Green for Unclassified. When ISs have similar classification levels but require separation for other reasons, the use of unique colors for different ISs or networks is permissible. These banners will identify the IS if space is available
Modify the screen backgrounds for each IS attached to the KVM switch to comply with the guidance given in the STIG.

unambiguously about these things.
