AdderView Secure (PPS 4.0) KVM Switches

Secure (PPs 4.0) KVM switches

with analog audio support 

AdderView secure (PPs 4.0) KVM switches enable a keyboard/video/mouse plus audio console to be shared between different classification level computers. Designed for superior usability, the KVM switches feature configurable LED buttons and a real-time status display.

AdderView secure (PPs 4.0) KVM switches are designed to prevent sensitive data leakage and data storage in the KVM switch. Using features such as uni-directional data paths, anti-tampering labels, and non-reprogrammable firmware, the secure KVM switches actually combats a range of potential threats.

Hardware Anti-Tampering
Holographic anti-tampering labels protect the product's enclosure, providing a clear visual indication if it has been opened or compromised. The secure KVM switch and also the smart card reader use holographic tamper evident labels to provide visual indications in case of an enclosure intrusion attempt.

Uni-Directional Keyboard and Mouse Data Paths
Uni-directional optical diodes ensure data paths travel in only one direction, thus preventing data leakage through shared peripherals. A uni-directional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.

Uni-Directional Video
Computer video input interfaces are isolated through use of separate electronic components and power. The display is isolated by a dedicated, read-only, EDID (Extended Display Identification Data) emulation for each computer. Access to the monitor's EDID and MCCS (Monitor Control Command Set) commands are blocked.

Uni-Directional Audio
Enforces computer-to-speaker one-way flow of sound through uni-directional optical data diodes, This prevents eavesdropping and line-in re-tasking by blocking speaker-to-computer communication.

No Shared RAM between Channels
The keyboard and mouse processor is powered down and reset at each switchover to thwart shared RAM leakages. All data buffers are actively cleared once they have been used.

Non-Reprogrammable Firmware
There is no access to the product's firmware or memory through any port. Firmware is permanently stored in non-reprogrammable read only memory (ROM) to prevent modification. Firmware integrity is verified through a self-test procedure during power up. Detection of a critical failure disables the device and provides a clear visual indication to the user.

Restricted USB Function
The USB ports will only accept HID (Human Interface Devices), such as keyboards and mice. Other devices, such as USB storage drives, are actively prohibited.

CAC Support
CAC support is provided through the use of the optional AS-4CR secure card reader (purchased separately - see listing below), which allows a single user's smart-card to simultaneously authenticate with up to 4 isolated computers.

Status Display
The status display shows the current channel number, channel name (if configured), audio channel and hold status, plus security classification (if configured). It also indicates whether the KVM switch is under remote control.

Audio Hold
Assign the audio port to a specific computer while switching the KVM switch to another computer. This front panel button (also replicated on the optional remote control unit) allows you to take the audio output from one computer while operating on another. Useful when a user needs to listen to audio from one computer while working on another.

Switching Between Channels
• Front-panel buttons
• Optional remote control unit (AS-4RCU)
• Free-Flow feature in KM configuration to switch channels as your mouse pointer crosses a video display boundary

Optional USB Port Expander
The USB port expander (purchased separately - see listing below) provides an additional USB port for applications that require a touch-screen device in addition to keyboard and mouse. It also provides advanced  protection incorporating physical and programmed protection of computer USB ports.

Optional Remote Control Unit
The optional remote control unit (purchased separately - see listing below) allows the operator to change channels when the secure KVM switch unit is not within reach. When a remote control unit is connected, the front panel buttons will have no effect, however, the button indicators will continue to reflect the current channel selection, as determined by button presses on the remote control unit.
