Common Display System (CDS)

Open, Multiple Independent Level Security Enterprise Display Solution

The Common Display System (CDS) product family consists of a series of information-display configurations based on standardized, interchangeable components that can be implemented across all classes of U.S. Navy ships. It allows sailors to access various applications at different classification levels from any console. By simultaneously displaying information classified at multiple independent security levels, the number of required systems onboard a ship are decreased, reducing cost of ownership and maintenance requirements.

  • Access to applications at any platform display workstation
  • Users can chat in multiple security domains on same console
  • Configurable design with common components reducing part count and lowering operating costs
  • Open architecture design enables quick technical insertions
  • Adaptable to any environment

Open Architecture Design

CDS is one of the first systems designed to fully implement multiple independent security levels on an open architecture platform. It is built on an open architecture design to ensure interoperability and enable frequent technology updates. It is a critical component of the Navy’s Open Architecture Computing Environment (OACE) initiative to modernize the Navy infrastructure and reduce life cycle costs. Building on the General Dynamics open computing infrastructure (OPEN CI), our team is developing for the Navy a flexible and configurable design with a multi-level, independent security function.

Commonality Of Components

The CDS product family consists of a series of display configurations based on standardized interchangeable components. By using common components, the number of parts are decreased and the streamlined production and ordering creates a further cost savings. It also reduces the amount of physical hardware—delivering additional weight, space and power savings. CDS uses a modular open systems approach for long term supportability, interoperability and growth for future modifications.

Multiple Independent Level Security And Information Assurance

CDS enables simultaneous display of multiple security domain information on the same display. This eliminates the need for separate machines to manage and enforce data separation at multiple classification levels. This feature fully supports the Navy requirement to enable on display communications through multiple networked “chat” functions—both classified and unclassified. CDS software is designed in accordance with DODI 8500.2 and with the High Robustness, Secure Kernel Protection Profile. CDS supports Real-Time Operating Systems, NonReal-Time Operating Systems (POSIX compliant) and co-hosts multiple operating systems simultaneously (Linux, Solaris, Windows, LynxOS). It also supports multi-core processors and employs hardware assisted virtualization to take full advantage of the evolution of security features on the newest chipsets.
