Manage secure keyboard and mouse operations on four (4) computers over multiple displays

A secure keyboard and mouse (KM) switch is a device that is specifically designed to enable isolation between connected computers.

These computers are typically connected to different networks, and isolation between these networks must be assured to prevent data leakages and intrusions.

Secure KM switches rely on physics (optical diodes) to prevent data leakages between coupled networks. Secure KM switches do not require any cables between computers, any shared bus or network, or any installed software.

4-Port Secure Keyboard and Mouse Switch
K304 provides users with a secure solution to switching keyboard and mouse (KM) control of four computers, each use multiple displays. With support of up to 16 total displays, users can create the ultimate in secure KM management.

Common CriteriaK304 is a superior solution to operating an environment of connected computers with multiple displays. Users can simply connect the monitors directly to the computers and use K304 to switch between computers for secure KM operation. Additionally, device's administrator mode provides many customized settings from display arrangement and size to cursor speed and acceleration.

Audio output can also be configured to follow the cursor or can be set by the user to any channel.

K304 offers impressive levels of communications even when connecting computers that are on different levels of security clearance and Internet access. K304 utilizes unidirectional optical data-diodes which insulates all connections from any possible points of data leakage among peripherals. K304 also securely filters and locks USB ports preventing data export/import through mass-storage devices by hardware.

Every K304 secure KM switch is rigorously and extensively tested to ensure it will remain stalwart against any known form of KM and KVM security attacks. K304 is specifically designed – and has been used – for national security applications. The unit has been certified to meet EAL 4+ standards to assure it provides the highest level of security possible.

Virtual Display Technology

After manufacturing, each unit is provided with a special holographic tampering-evident label to ensure the device has not been tampered with.

Virtual Display Technology
Virtual Display Technology (VDT) is a cornerstone of K304's functionality. VDT enables seamless cursor and keyboard switching between multiple computers by simply moving the cursor to that computers display(s). VDT allows administrators to configure any desired displays configuration with same or different size and resolution. Move the cursor from one screen to the next, and the keyboard/mouse switching occurs instantaneously, switching to the computer associated with the screen your cursor is on.

K304 enables field configuration loading of any desirable custom display arrangement. This product supports up to 4 computers that may drive up to 16 displays.

Multi-Head Computer Operation
K304 allows up to 16 displays to be used with its four connected computers. This means multiple multi-head computers can be managed with the device's automatic KM switching. Users can implement four dual-head computers, for example, or four quad-head computers, etc.
