The ServSwitch Secure KVM Switch with USB, EAL4+ Certified/TEMPEST Level I (Level A) Qualified, VGA, surpasses the security profiles of most other KVM switches. In addition to its superior hardware-based data-isolation features, the switch has been certified for Common Criteria Evaluation Assurance to Level 4+ (EAL4+), augmented by ALC_FLR.2 and ATE_DPT.2. The Common Criteria is an international standardized process for information technology security evaluation, validation, and certification. The Common Criteria scheme is supported by the National Security Agency through the National Information Assurance Program (NIAP). EAL4+ itself defines a common set of tests to evaluate the security of an IT product relating to its supply chain, from design and engineering to manufacturing and distribution. The ServSwitch Secure KVM Switch with USB, EAL4+ Certified/TEMPEST Level I (Level A) Qualified, VGA provides control and separation of two PC CPUs/servers connected to secure and non-secure networks through just one keyboard, monitor, and mouse. Users can safely switch among the connected computers operating at different classification levels without worry. Plus, it is TEMPEST USA NSTISSAM Level I and NATO SDIP-27 Level A qualified. What this means is the low radiated emissions profile of the switch meets the appropriate requirements for conducted/radiated electromagnetic emissions. The TEMPEST designation is required by military organisations. As a security standard, it pertains to technical security countermeasures, standards, and instrumentation that prevent or minimise the exploitation of vulnerable data communications equipment by technical surveillance or eavesdropping.
