Sophisticated KVM systems offer peace of mind

Cyber threats are constantly evolving, becoming more frequent and more sophisticated every day. The physical connections between computers and peripherals are no exception and, if left unsecured, can be vulnerable to attack. KVM extenders can be used to back-rack computers and servers to secure data centers, restricting physical access to critical hardware. While KVM desktop and matrix switches provide access to multiple computers from a single user station, they are typically not connected to any network and provide a means to restrict access to a limited group of users and even USB ports. That’s why KVM technology is not only making remote shared access to computers easier, but it’s also a great way to physically safeguard your equipment by adding an additional secure layer for accessing critical hardware.

The most straightforward way to improve security is to reduce physical access to ports and other hardware systems. Anytime you connect computer peripherals such as a keyboard or mouse to a PC, you open the door to potential data leakage, alongside hacking risks and vulnerabilities. After one breach, that door is then potentially opened for further mischief.

The more sophisticated KVM matrix switching systems available today allow administrators to restrict access to USB ports. As a result, only users with appropriate access rights and credentials can plug in USB devices and copy data. The management system you choose should facilitate fast and easy configuration of these rights and credentials. Secure KVM switches also will not accept any USB device that hasn’t been specified by system administrators.

Going one step further, certified secure KVM solutions address the stringent security requirements of defense agencies and other organizations that demand advanced security measures. This includes tamper-proof device housings, opto-isolated circuits, and other hardware-related measures to prevent malicious access to your data. If you’re investing in new equipment, you can take advantage of devices certified according to the Protection Profile for Peripheral Sharing Switch (V3), which assesses the design, testing, verification, and shipping of security products.

If you’re looking to boost security, you should consider the Black Box NIAP 3.0-Certified Secure KVM Switch line, which provides port isolation between networks to ensure that zero data is leaked between secure ports and the outside world. Built with true data path isolation between systems, these switches can help you prevent hardware tampering and malicious attacks.

Whatever measures you choose to adopt, just remember that it’s preferable (and less costly) to prevent an attack than to clean one up after a successful hack.
