Overview
Security Features
Product is designed, manufactured and delivered in security-controlled environments. Below is a summary of the main advanced features
incorporated in product:
Advanced isolation between computers and shared peripherals
:
The emulations of keyboard, mouse and display EDID, prevent direct contact between computers and shared peripherals. Product design
achieves maximal security by keeping the video path separate with keyboard and mouse switched together, purging keyboard buffer when
switching channels. All these features contribute to strong isolation between computer interfaces, maintained even when product is powered off.
Unidirectional data flow: USB, audio and video:
Unique hardware architecture components prevent unauthorized data flow, including:
Optical unidirectional data flow diodes in the USB data path that filtrate and reject unqualified USB devices;
Secure analog audio diodes that prevent audio eavesdropping with no support for microphone or any other audio-input device;
Video path is kept separate from all other traffic, enforcing unidirectional native video flow. EDID emulation is done at power up and blocks
all EDID/MCCS writes.
Isolation of power domains:
Complete isolation of power domains prevents signaling attacks.
Always-on, active anti-tamper system:
Active anti-tampering system prevents hardware implants and wireless key-loggers. Any anti-tampering attempt causes isolation of all computers
and peripheral devices rendering product inoperable and showing clear indications of tampering event to user.
Holographic security tamper-evident labels are placed on the enclosure to provide a clear visual indication if product has been opened or
compromised. Metal enclosure is designed to resist mechanical tampering with all microcontrollers protected against firmware-read, modification
and rewrite.
Tamper Evident Labels:
I/O Secure KVM Switch uses holographic tamper evident labels to provide visual indications in case of enclosure intrusion attempt.
If for any reason the tamper evident seal is missing, appears disrupted, or looks different than the example shown here, please avoid using
product and call I/O Technical Support at: (
1 (714) 564-1111
).
Active Anti-Tampering System:
I/O Secure KVM Switch is equipped with an always-on active anti-tampering system. If mechanical intrusion is detected by this system, the Switch
will be permanently disabled and LED will blink continuously with relay clicking. If product indication tampered state (all LEDs blinking and relay
clicking) - please call Technical Support and avoid using that product.
