System information

Why are the LEDS of the
Num Lock and Caps Lock
keys disabled?
Belkin Secure KVM blocks all data sent from the
computer to the keyboard in order avoid attacks
that use keyboard inherent security vulnerabilities
(one example is the keyboard mailbox attack).
Hardware - controlled unidirectional data ow
allows the keyboard to communicate in only
one direction, preventing the keyboard from
receiving data from the computer. Keyboard
strokes are sent from the keyboard to the
connected computer, any commands sent from
the computer to the keyboard will be blocked
e.g. Num Lock and Caps Lock keys LEDs.
How does the Belkin Secure KVM
reduce the risk of user errors?
1. Color coded chips can be used to
associate the port with the network, and
port button illumination indicates which
computer the console is controlling
2. Audible indication when switching channels
3. Optional Desktop Controller Unit (DCU)
with clear visual indications of channels
available and selected
Are Belkin Secure KVMs Failsafe /
High Assurance products?
Yes, all Belkin Secure KVMs are designed and
tested for failure modes to assure that even in
the most severe failure modes; data would not
leak through the product. Belkin Secure KVM
products rely on physics (conversion of data to
light) to assure that even if microcontrollers fail,
data would not leak between computers. This
level of assurance is critical when connected
networks are of varying security levels (secret,
top secret, etc.). Belkin Secure KVM products
are designed to prevent a single point of failure.
Data streams are fully isolated, and secure, even
in the remote event of severe hardware failure.
How does the Belkin Secure KVM
prevent unauthorized USB
peripheral usage?
The Belkin Secure KVM is equipped with
specic ports for Keyboard and Mouse only.
Peripherals connected to USB hubs are not
supported to prevent potential hacking or
social attack. The Belkin Secure KVM product
features a dedicated processor per computer
port to emulate peripheral devices. This keeps
each computer running on different security
levels physically separated and secure at all
times, and prevents any unintended data leakage
between computers. Optical diodes are used
to enforce unidirectional data ow from the
peripheral devices to computers preventing
potential leakage paths between computers;
even in the event that one of the connected
computers becomes compromised.
What is the Belkin Secure KVM
active anti tampering system?
The Belkin Secure KVM active anti tampering
system consists of unique electronic sensors
that render the KVM permanently inoperable
when the chassis is opened. The active anti
tampering mechanism is battery-backed, and
always-on, with a life span of over 15 years;
making the Belkin Secure KVM one of the most
reliable KVM switches in the industry.
