1 PRODUCT OVERVIEW
Cybex™ SC switches are field-proven, secure, KVM and KM switching solutions with special support for
government agencies. This switching system allows users to switch safely between computers operating
at different classification levels from a single set of peripherals, providing continuous access to critical
data. With multiple security features, the secure design prevents the transfer of data between the
connected computers, ensuring data security is not compromised.
WARNING! This product is equipped with active intrusion protection and tamper-evident seals.
Tampering with the switch or breaking/removing the seals will permanently disable it and void

1.1 Features and Benefits
The SC switching system offers the following options, depending on the model:
•Support for HDMI, DVI-I, VGAand/or DisplayPort video
•Support for Common Access Card (CAC), USB biometric device and USB authentication token
•Certification to Evaluation Assurance Level (EAL) 4+
•Support for USB and PS/2 keyboard and mouse

FEATURE DESCRIPTION
Complete
network
segmentation
Data flow is controlled and insulated from peripheral devices using optical data diodes. EDID emulators and
internal firewalls protect shared displays and prevent external memory leaks.
Protection from
shared
resources
The switches are designed to securely operate, even when peripheraldevices are vulnerable to signaling attacks.
They do not allow computer access to any shared resource and do not share controllable power sources.
Non-
reprogrammable
firmware
Custom firmware is not reprogrammable preventing the ability to remotely attack switch controllers.
Audio
protection Microphone switching is not supported to prevent data leaks through audio ports.
CONSOLE USB
port protection
CONSOLE USB ports protect from the use of unsafe USBstorage devices. Unqualified devices are rejected when
connected through the switch even though keyboard and mouse data is passed through.
