A programmable keyboard, video, mouse (KVM) switch with a cut-and-paste buffer can enforce a multi-level security policy. The KVM switch ports are configured with labels that properly indicate the security level that is assigned to each computer, and each of the ports is connected to a computer that matches the security level of the configured port label. The KVM switch displays the current level of security on the computer’s video monitor and on the KVM switch indicator. The KVM switch provides the marking of security levels independent of any input from the computers to which the switch is connected.
