The AdderView Secure AVSD1004-US KVM switch enables a keyboard, monitor and mouse to be shared between high and low security systems, sometimes known as red and black networks, and is designed carefully to prevent information flowing between computers or to the outside world via emissions snooping. The AdderView Secure design prevents sensitive data from leaking between ports, sensitive data leaking to the outside world and sensitive data from being stored in the device. Additionally, the switch actively combats a range of potential leakage "threats".
Uni-directional data paths for keyboard and mouse: One-way data paths ensure that data isolation is assured by hardware, rather than by microprocessor software and protect against timing analysis or forced malfunction attacks.
Designed for minimal electromagnetic emissions and isolation of electrical crosstalk: Extensive shielding of the outer casing and of internal circuitry along with 60dB crosstalk isolation ensures that less than 1/1000th of any signal is transferred to another computer. External probing and unauthorized internal access are prevented through the unit design, with as few apertures as possible.
No shared RAM between ports: The keyboard and mouse processor is powered down and reset at each switchover to prevent shared RAM leakages. Separate memories hold the Num, Caps and Scroll states with limited accessibility and all data buffers are actively cleared once they have been used.
Hardwired port isolation: Data Diodes implemented within hard-wired electronic circuitry ensure unidirectional flow of critical data paths, safeguarding any compromised peripheral by preventing reading of information or transfer of data by another system. Peripherals are always powered down and re-initialized in the event of a change of channel, providing an additional of protection against hidden peripheral malware.
