The IOGEAR Secure KVM products implement a secure isolation design for all models to share a single set
of peripheral components. Each peripheral has its own dedicated data path. USB keyboard and mouse
peripherals are filtered and emulated. DisplayPort video from the selected computer is converted
internally to HDMI, then back to DisplayPort for communication with the connected video display and the
AUX channel is monitored and converted to EDID.
The Secure KVM Switch products are designed to enforce the allowed and disallowed data flows between
user peripheral devices and connected computers as specified in [PSD]. Data leakage is prevented across
the TOE to avoid compromise of the user's information. The Secure KVM Switch products automatically
clear the internal TOE keyboard and mouse buffers.
Figure 1 shows the data path design using a 2-Port KVM as an example.
