The ADDERView Analog Standard SecureSwitch (AVSV1004) allows a keyboard, monitor and mouse to be shared between high and low security systems, "red and black networks". The high density, highly robust, small form factor unit ensures maximized security to prevent the compromise of critical data.
The ADDERView Secure range of products are highly robust KVM switches for critical applications. When information absolutely must not be leaked between systems or networks, the ADDERView Secure units combine the necessary isolation with a desirable ease of use.
ADDERView Secure units combine a number of overlapping strategies that are designed to defeat potential points of infiltration or protect against user error.
TEMPEST Qualified
Tempest certified design (USA NSTISSAM Level I and NATO SDIP-27 Level A).
EAL4+ Certified
Independently tested against common criteria, the AVSD achieves Evaluation Assurance Level 4+. CERTIFICATION REPORT No. CRP259
EAL2+ Certified
EAL2+ Common Criteria Evaluation Assurance Level 2 (augmented by ALC_FLR.2) COMMON CRITERIA (ISO 15408) ASSURANCE LEVEL and Peripheral Sharing Switch (PSS) For Human Interface Devices Protection Profile, IAD, Version 2.1, 7 September 2010. CERTIFICATION REPORT No. CRP268
Hardwired Port Isolation
Data Diodes, implemented within hard-wired electronic circuitry, rather than software, are liberally employed to ensure that critical data paths can flow only in one direction. These data diodes ensure that a compromised peripheral, a keyboard for instance, cannot read information back from a connected system in order to transfer such details to another system. Whenever a channel is changed, the connected keyboard and mouse are always powered down and re-initialized to provide yet another level of protection against hidden peripheral malware.
No Critical Software Reliance
In general, the role of software within the unit has been reduced to an absolute minimum to avoid the possibility of subversive reprogramming. Additionally, all flash memory has been banished from all security critical areas of the design, to be replaced by one-time programmable storage which cannot be altered.
Minimal Emission Design
The outer casing contains extensive shielding to considerably reduce electromagnetic emissions. Additionally, the casing has been designed with as few apertures as possible to reduce the possibility of external probing and several primary chassis screws are concealed by tamper-evident seals to indicate any unauthorized internal access. Shielding extends also to the internal circuitry with strong levels of electrical crosstalk isolation between ports to protect against signals from one computer becoming detectable on another.
Physical Port Identification
ADDERView Secure units are available in two port and four port sizes. Each size can be ordered in standard and enhanced versions. The enhanced versions allow you to attach a smart card reader that can be securely shared between the connected systems. The enhanced versions also contain anti-subversion and authentication features that guard against intrusion and allow you to prove that the unit is genuine, respectively. These are just a few of the many strategies and innovations that have been combined to reinforce the separation between differing systems. Numerous other defences lie in wait to defeat potential threats.
