ATEN CS1142DP Overview

  • 1Description

The 2-Port USB DisplayPort Dual-Display Secure KVM Switch from ATEN is designed to meet the stringent security requirements of defense and intelligence installations. It is compliant with the PSS PP v3.0 (Protection Profile for Peripheral Sharing Switch, Version 3.0) standard certified by the National Information Assurance Partnership (NIAP), ensuring high-level desktop security and data safekeeping. This two-port model uses a DisplayPort dual-display video interface and supports video resolutions of up to 4K UHD (3840 x 2160) at 30 Hz.

The CS1142DP provides isolation between up to two computer sources and their peripherals while sharing a single keyboard, mouse, monitor, speaker set, and Common Access Card (CAC) reader. Compliance with PSS PP v3.0 ensures high user data security when switching port focus, preventing unauthorized data flows or leakage between connected sources. Key protections include isolation and unidirectional data flow, restricted peripheral connectivity and filtering, user data protection, configurable device filtering and management, and always-on tamper-proof design, providing advanced security and a user-friendly design for instant deployment.

Up to 4K video output resolution at 30 Hz
Port selection only via pushbuttons to enhance security
Video DynaSync technology eliminates boot-up display problems and optimizes resolutions when switching between ports
Supports enable/disable CAC function by port
LED indicators for peripheral filtering and KVM security status
Rugged metal enclosure
Built-in power
Supports analog audio (speaker only)
NIAP Common Criteria Compliant
The CS1142DP is compliant with PSS PP v3.0 (Protection Profile for Peripheral Sharing Switch, Version 3.0) security requirements.
Multi-Layered Security
  • Restricted USB connectivity: Non-authorized HIDs (Human Interface Devices) and non-predefined CAC devices are rejected/ignored.
  • Always-on chassis intrusion protection renders the CS1142DP inoperable when physical tampering is detected.
  • Tamper-evident seal provides visual indication of any attempt to access the CS1142DP's internal components.
  • Non-reprogrammable firmware prevents reprogramming of the CS1142DP.
Data Channel Isolation and Unidirectional Data Flow
  • Data channel isolation prevents data leakage between connected computers via isolated channel per port.
  • The data flow between the console devices and the selected computer is unidirectional.
  • The CS1142DP controls and isolates data flow between the console devices and the connected computers.
  • To ensure user data protection, the keyboard/mouse data buffer is automatically purged when switching KVM port focus.
Security Management
  • KVM log data provides administrative functions for an authorized administrator to audit KVM log data.
  • The USB CAC Port can be configured to allow/reject whitelisted/blacklisted devices via the Admin logon function or Windows-based application.
