Switchview SC (Secure)
1x4 KVM Switch
If you are reading this page, you likely know what a "KVM" Switch is.
That is, a device that allows you to use one keyboard, monitor and
mouse with a number of different computers. When connected properly, a
simple series of keystrokes takes you from one computer system to
another. These can be very nice for anyone using more than
one
computer in the same location, and virtually invaluable for system
operators. Now for what you might not know. It is often desirable, from
a security perspective, to isolate your internal secure LAN from
external public networks, like the internet. This is often done with
firewalls, or in more secure installations, by completely isolating the
two networks from one another. In other words, no computer on the
internal secure network is also on the outside, unsecure network. This
precludes the possibility of someone hacking into the common
computer(s) and finding their way onto your secure network. This much
is pretty common knowledge. What is less well known is that if the
system administrator, or other person, has access to computers on both
of these networks via a KVM, a savvy hacker, compromising the public
network computer, can possibly also gain access to critical data from
the secure network computer via the KVM itself! This is a
little
known, but never the less, very dangerous security hole which is very
easy to plug. That's where the line of Avocent/Cybex Secure KVM Devices
comes in:
Here's what the manufacturer says:
"If you access secure and
non-secure networks, you can rely on the SwitchView SC switching system
to keep your private data completely separate and secure at all times.
The SwitchView SC switch is specifically designed to make unintended
data transfer between connected computers virtually impossible
– an
important factor for maximum security installations."
