D) How secure are KVM Switches ?

Depending on the model you buy the User has the ability to have Password controlled access to their switch restricting unauthorised Users. If you are accessing the switch via IP then these often use 128 bit SSL encryption, and users must enter security codes which are hardware-based as opposed to software-based, making it even more difficult for any potential hacker. Devices also capture, digitise, and compress the video signal before transmitting to a remote PC, giving secure real-time control.
