STOP™ Version 7 Trusted Operating System

Secure Operating System

STOP 7 is the premier secure operating system (OS) that provides flexible security policies, a Linux™ compatible Application Programming Interface (API), and high performance. STOP 7 gives defense, intelligence community (IC), government, and enterprise solution providers and integrators a trustworthy and robust foundation for developing trusted information sharing, guarding, and server applications.

STOP 7 is the successor to the STOP 6 operating system used to power the XTS-400™ trusted computing platform, the first and only such general-purpose computer system in the world to achieve Common Criteria Evaluation Assurance Level EAL 5+. While both products are designed and built from the ground up with security as the primary feature, STOP 7 improves on the performance and flexibility of its predecessors. By delivering top-notch processing and network performance, it rivals and even tops performance figures of commercial off-the-shelf operating systems.

Flexible Security Policy

STOP 7 provides flexible ways to secure an organization’s sensitive information assets:

  • Role-Based Access Control (RBAC): a flexible, permission-based mandatory access control policy
  • Bell-LaPadula multi-level security policy: a mandatory read-down/write-up policy
  • Biba multi-level integrity policy: a mandatory read-up/write-down policy
  • Multi-compartment security and integrity for Bell-LaPadula and Biba policies
  • Traditional UNIX-style discretionary access control (DAC)

These security policies can be used separately or in conjunction to provide robust, granular system and data protection. Solution providers can leverage this flexibility to tailor a customized security policy that meets unique agency needs.

Trusted Applications with High Assurance

STOP’s Linux®-like programmatic interfaces enable developers to port or develop applications easily on the system. These applications generally reside outside the system’s Target of Evaluation (TOE), making them easier to certify and accredit while still deriving a high degree of security and integrity from the underlying mandatory protection mechanisms in the TOE. The STOP operating system and XTS platform are used in over 700 cross-domain deployments worldwide. Several of these deployments include accredited high assurance guard applications that provide strict control over automated sharing of information among networks with different sensitivity classifications.

Flexible Deployment Options

STOP 7 is designed to be portable, flexible, and mobile in its deployment options. The OS can be deployed on a wide range of platforms from the server room to the tactical edge, including:

  • Single-board computers (SBC)
  • Embedded devices
  • Virtual appliances

This hardware flexibility opens the door to tactical deployments such as aboard aircraft, in command vehicles, in backpacks, etc. These are critical to current and future tactical information sharing programs, particularly those with cross-domain requirements. More, STOP 7’s combination of features and performance allow for a wide range of application possibilities from traditional guards to file servers and network routing.
