ServSwitch Secure VGA USB KVM Switch EAL4+/TEMPEST
Combat security threats with this hard-wired VGA KVM switch featuring CAC support for maximum protection against data leakage.
- Facilitates data separation with high-level electrical isolation between ports.
- Protects against signal snooping using 60-dB crosstalk isolation.
- Prevents access from one CPU or network to others through permanent hard-wired connections.
- Minimizes radiated emissions.
- External tamper-evident seals.
- Robust metal housing with durable switching mechanism.
- USB host controller erases entire RAM—no residual data remain on channel.
- Dedicated DDC bus and EDID emulation at each port.
- Options with CAC (Common Access Card) reader support available.
- Clear, unmistakable channel selection with non-flashable ROM.
- No common power supply to minimize signaling.
- Warranty: 2 Years Double Diamond™ (Standard)
The ServSwitch™ Secure VGA USB KVM Switch with EAL4+/TEMPEST exceeds standard security profiles, certified to EAL4+ (Common Criteria Evaluation Assurance Level 4+) with ALC_FLR.2 and ATE_DPT.2.
The Common Criteria is an international standard for IT security evaluation, supported by the NSA through the NIAP. EAL4+ ensures product security throughout design, manufacturing, and distribution processes.
This KVM switch enables safe control and separation of up to four computers connected to secure and non-secure networks through a single keyboard, monitor, and mouse.
TEMPEST
TEMPEST compliant at USA NSTISSAM Level I and NATO SDIP-27 Level A, ensuring minimal electromagnetic emissions to prevent data vulnerabilities.
CAC (Common Access Card) Support
Models SW2009A-USB-EAL and SW4008A-USB-EAL support CAC card readers for enhanced security functions.
Threat Scenarios and Solutions
1. Prevent data leaks between ports and externally.
Threat 1.1: Unidirectional keyboard and mouse data flow is enforced by hardware “data diodes.” Non-keyboard USB devices are inhibited.
Threat 1.2: Red and black ports are physically separated to improve data isolation.
Threat 1.3: All hotkey and mouse switching functions are locked down, preventing inadvertent channel changes.
Threat 1.4: Each port has independent USB power, avoiding cross-port interference.
Threat 1.5: Minimum 80-dB crosstalk isolation prevents signal snooping.
Threat 1.6: Only one computer is connected to shared circuitry at a time, blocking timing analysis.
Threat 1.7: Shielded cables and filtered power minimize electromagnetic emissions.
2. Prevent data retention in the device.
Solution: Volatile memory is erased with each channel change, preventing residual data transfer.
3. Prevent electronic snooping.
Solution: Double-shielded metal casing blocks eavesdropping.
