Product Description

The High Sec Labs Secure Peripheral Sharing Switches (PSS) allows the secure sharing of a single set of peripheral components such as keyboard, Video Display and Mouse/Pointing devices among multiple computers through standard USB, DVI, HDMI, and DisplayPort interfaces.


Evaluated Configuration


Security Evaluation Summary

The evaluation was carried out in accordance to the Common Criteria Evaluation and Validation Scheme (CCEVS) process and scheme. The evaluation demonstrated that the product meets the security requirements contained in the Security Target. The criteria against which the HSL Secure KVM was evaluated are described in the Common Criteria for Information Technology Security Evaluation, Version 3.1, Revision 4. The evaluation methodology used by the evaluation team to conduct the evaluation is the Common Methodology for Information Technology Security Evaluation, Version 3.1, Revision 4. Computer Sciences Corporation determined that the product is conformant to requirements for Peripheral Switch Protection Profile version 3.0.  The product satisfies all of the security functional requirements stated in the Security Target. Two validators, on behalf of the CCEVS Validation Body, monitored the evaluation carried out by Computer Sciences Corporation. The evaluation was completed in February 26, 2016. Results of the evaluation can be found in the Assurance Activity Report for HSL Secure KVM prepared by CSC Global Cybersecurity.


Environmental Strengths

Keyboard and mouse security

Isolated keyboard and mouse USB device emulators per connected computer to prevent direct interface between the TOE shared peripheral devices and connected computers.

TOE uses host (computer) emulators to interface with connected keyboard and mouse peripheral devices, thus isolating external peripherals from TOE internal circuitry and from connected computers.

Keyboard user data is not stored on TOE non-volatile memory.  All USB stacks are implemented in the TOE using SRAM (Static Random Access Memory) – a volatile memory that clears data once TOE is powered down.

TOE external interface security

The TOE supports only the following external interfaces protocols:

           USB keyboard and mouse;

           Analog audio output;

           User authentication device or other assigned USB devices (TOE model specific);

           Power (AC or DC); and

           Video (VGA, DVI, HDMI, DisplayPort or MHL video only).

Audio Subsystem security

The TOE audio data flow path is electrically isolated from all other functions and interfaces to prevent signaling data leakages to and from the audio paths.

Video subsystem security

Video input interfaces are isolated from one another. Isolation is achieved through the use of different power and ground planes, different electronic components and different emulated EDID chips per channel.

TOE supports Display Port 1.1, 1.2 and 1.3. TOE video function filters the AUX channel by converting it to I2C EDID only. DisplayPort video is converted into HDMI video stream.

User authentication device subsystem security

TOE supports User Authentication Device function (called DPP or fUSB). These products are configured by default as FDF (Fixed Device Filtration) with filter set to qualify only the following devices:

           Standard smart-card reader USB token or biometric authentication device having USB smart-card class interface complying with USB Organization standard CCID Revision 1.1 or ICCID Revision 1.0.

Note that device must be bus powered

           A qualified administrator after successfully logging-in to the TOE administrative function may switch the TOE to CDF (Configurable Device Filtration) mode.

User control and monitoring security

TOE is controlled and monitored by the user through front panel illuminated push-buttons and switches. These controls and indications are coupled to the TOE system controller function.

Tampering protection

Always-on anti-tampering system mechanically coupled to the TOE enclosure to detect and attempt to access the TOE internal circuitry.

TOE is equipped with special holographic Tampering Evident Labels that located in critical location on the TOE enclosure.

Self-testing and Log

TOE is equipped with self testing function that operating at TOE power up prior to normal use. The self-test function is running independently at each one of the TOE microcontrollers following power up.

TOE is equipped with event log non-volatile memory that stores information about abnormal security related events. A qualified administrator can log-on is to view and dump the log to a notepad.
