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 IAO, the SA, and the user will ensure that no peripheral other than the keyboard, video, or mouse is connected to the KVM.
