Aten CS1184 USB & DVI 4 port Secure KVM switch is NIAP-certified and passed the Evaluation Assurance Level 2 (EAL2+) requirements for Peripheral Sharing Switch (PSS) for Human Interface Devices (HIDs) Protection Profile v2.1, satisfying the latest security requisites set by the U.S. Department of Defense for peripheral switches. Compliance ensures maximum information security while sharing a single set of HIDs (keyboards, mouse, speakers, etc.) between multiple computers. Conformity with Protection Profile v2.1 certifies that other USB peripherals cannot be connected to the console ports of the CS1182, and that only a keyboard and mouse are accommodated, therefore providing high-level security, protection and safekeeping of data.
