How Secure Is the KVM-over-IP Switch?

A multi-computer switch (KVM) is a computer management device that enables multiple computers to be controlled with a single set of keyboard, mouse, and monitor. KVM-over-IP switches, also known as digital KVM switches, are widely used nowadays, and their security issues are becoming more and more vital, so what about the security of KVM-over-IP switches?

1. Meet the KVM-over-IP Switch

As the only interface for managing multiple servers, the security of KVM over IP Switch is very important. Analog KVM switches are limited by their scope of use and require only a clear division of IT management and console access to greatly enhance security. On the other hand, because KVM-over-IP switches are network-based products, can be accessed through the network as long as the IP address is known, so the security requirements for the device are much higher.

The security issue is not only about the security of the output data, but also about the security of user accounts. Since KVM is an open system based on IP network, user accounts can be stolen by hackers or network listeners with ulterior motives. In addition, it is also important to look at the hot backup capability and ease of maintenance of the centralized management of the KVM system, especially whether the users can maintain it themselves.

In terms of transmission, analog signals are higher than digital signals for KVM in security, because digital products transmit digital signals of keyboard, mouse, and monitor, so if they are stolen through the network, it will cause great security risks, then how to encrypt these signals is essential. The digital KVM encryption methods currently on the market are: SSL, DES, 3DES, etc., so be sure to understand them before purchasing a KVM-over-IP device. Transmission security is not only reflected in the encryption mode, but also in the video portion. Because the KVM devices use the incremental video transmission mechanism, which means that only the changed video part is transmitted. From the security point of view, even if the signal is stolen, it is not reversible.

The primary concern of the digital KVM solutions chosen by different companies is the security of KVM-over-IP. The fundamental purpose of KVM is to promote remote control technology for servers and PCs, but at the same time, there are risks naturally involved with the process. Companies should develop the crucial notion that they should never skimp on security when implementing KVM-over-IP. Security remains paramount in the realm of KVM over IP HDMI technology, KVMoIP solutions, and control room display setups. With the digital KVM switcher, security considerations encompass both data output and user account safety. While digital signals enhance transmission, encryption methods like SSL, DES, and 3DES play a pivotal role in safeguarding signals. Ensuring robust security for KVM over IP is fundamental, emphasizing the importance of not compromising on security while embracing remote control solutions.
