What is a secure KVM Switch ?

People ask what is a Secure KVM Switch ?  And is is really any different to a good standard KVM switch ?  The answer is yes.

A secure KVM switch is a desktop switch that not only provides Keyboard, Video and Mouse control but the proper separation of the PCs connected to the different ports, which may be on networks of differing security groups.  Unlike standard KVM switches, secure KVM switches do not allow the use of hotkey commands to change channel this can only be controlled using push button control or special connected remote controls by the authorised user at the desk.

The computer ports give isolation between networks ensuring no data is leaked between the ports and potential threats, this sometimes done by changing circuitry to light diodes. Secure KVM Switches must truly break the physical connection to previous channels before reconnecting to the new chosen channel/port. In order to design a optimal environment to making mission-critical decisions, organisations must consider both secure function and to be desktop user friendly. Secure KVM switches provide a user-friendly but effective safety barrier for users operating in command and control environments.

Secure KVMs come with a wide range of features and additional options to further maximize overall efficiency and security. Secure KVM switches do not allow the use of just any USB drive that isn't recognised to access any information. But if required some switched can be configured to allow only USB devices that are selected as authorised or recognised. Such as CAC common access card readers.

Secure KVM switches are vital to protect this layer switch point and do even more to protect government agencies, utilities and authorities from modern critical cyber threats.
