Have you ever wondered how something as simple as a KVM switch can enhance cybersecurity in an IT environment? In this article, we’ll explain how these nifty devices can provide extra protection for your critical systems and data. From physical access control to network isolation, KVM switches can help strengthen your security posture.
What is a KVM Switch and How Does It Work?
A KVM switch is a hardware device that allows you to access multiple computers from a single keyboard, video monitor and mouse. It connects these accessories to multiple computers, to switch between the connected systems.
How Do KVM Switches Function?
KVM switches receive signals from the keyboard, mouse and monitor and send them to the selected computer system. They also receive video signals from the connected computers and transmit them to the monitor. KVM switches allow switching between computers through keyboard hotkeys, on-screen display menus, front panel buttons or a remote switch.
Some KVM switches provide additional features like
- Audio support to share speakers and microphones,
- USB hub to connect other USB devices,
- and Ethernet/serial connectivity for console management.
Advanced KVM switches offer enhanced capabilities such as video emulation to support varying video resolutions, hotkey macros and virtual media support for file transfers between systems.
How KVM Switches Enhance Physical Access Control?
As an IT administrator, restricting physical access to critical systems is one of your top priorities. KVM switches allow you to secure servers and workstations by consolidating access to multiple computers from a single keyboard, video, and mouse peripheral set.
Restrict Access to Authorised Personnel Only
With a KVM switch, you can place servers and workstations in a locked room or cabinet. This restricts access to only authorised data center personnel. Users can access the connected systems using the KVM switch from outside the restricted area. This helps prevent unauthorised access and tampering.
Isolate and Segregate Networks
Using a KVM matrix switch, you can connect systems on isolated networks to a single KVM switch. Then, restrict user access to only authorised networks. A KVM switch can connect workstations on both a standard business network and a PCI DSS compliant network. Upon connection, configure the switch to allow access to only one network at a time based on login credentials. This helps meet compliance requirements and prevents accidental crossover between secure and non-secure networks.
Enhanced Monitoring and Control
A KVM switch gives you a single point of control and monitoring for connected systems. You can use KVM switching software to view thumbnails of all connected systems. This makes it easier to select a target system to monitor or access. Some KVM switches also allow you to power cycle systems remotely through the software interface or an API. This simplifies administration and security auditing of critical systems.
Using KVM switches in secure areas can help restrict access, isolate critical systems, and enhance monitoring and control. This multifaceted approach improves security posture. and demonstrate compliance with industry regulations. Implementing the proper controls and safeguards at the hardware level, creates a solid foundation for audits.
