Tempest and EAL4+ Qualified Secure KVM Switches Launched

Adder Launches a Range of Next Generation Secure KVM Switches With Common Criteria EAL4+ Certification and a Tempest Level I Qualified Design

CAMBRIDGE, England, January 18, 2011 - Adder, the experts in connectivity solutions begin a new era in secure
KVM switching. Featuring a Tempest level I (level A) qualified design and
EAL4+ Common Criteria security certification, the new Adder secure switches
offer an assured and highly secure way to access red and black systems from a
single keyboard, mouse and display.

Designed from the ground up as a dedicated secure KVM switch, every
element of the switches has been conceived to ensure data isolation and
emission control. Dedicated secure KVM switches are designed for use by
Governments, Military, and Defence or in any environment where a user needs
to access networks that are operating at a different level of security or
classification.

Modern defence, counter terrorism and government agencies are more and
more reliant upon electronic systems which in turn provide an opportunity to
gather counter intelligence. Electronic emissions pose a threat to secure
systems as they provide a conduit by which sensitive information could leak
into the wrong hands. Video cables for example can emit strongly and these
emissions can be collected to display the same image elsewhere. Power sources
can also conduct data back into a mains electricity supply and this in turn
can be picked out using sensitive devices outside of the system's physical
location. Previous generation KVM switches that do not actively combat these
leakage threats may therefore pose a significant security risk.

Tempest testing was developed to ensure that sensitive equipment doesn't
leak information, although the exact nature and details of the tests are not
publicly available. Adder's new secure switch has been tested and qualified
to the strictest Tempest standards (USA NSTISSAM Level I and NATO SDIP-27
Level A). This means that the switches are amongst the lowest leakage KVMs in
the world. Alongside Tempest, the new Adder secure switches have also been
certified to Common Criteria Evaluation Assurance Level 4 (augmented by
ALC_FLR.2 and ATE_DPT.2). This EAL4+ certification is internationally
recognised and provides customer confidence in the security of the product
design. The switch also boasts an amazingly high level of crosstalk isolation
that is greater than 80dB giving further peace of mind.

What makes this switch particularly unique is the way that it implements
hardware-assured unidirectional dataflow meaning that keyboard and mouse
signalling paths cannot act as a data transfer conduit between computers even
if there are unknown bugs in the software (a potential weakness with other
approaches). Alongside this is the concept of data islands employing
revolving door techniques which keep up to four connected systems physically
separate rather than relying upon software to maintain separation. Active
tamper detection is also available that continuously monitors the hardware
for physical attack and permanently disables the switch if it is tampered
with.

Two and four port models are available together with models that support
CACs (Common Access Cards).
