XTS-400™ Trusted Computer System

The XTS-400 implements an evaluated mandatory integrity policy that can provide files, data, and applications unparalleled protection from unauthorized tampering by malicious users or rogue software.

The XTS-400 was evaluated at the Common Criteria EAL5 augmented level. It is one of the few systems that protects your data and enterprise processing environments from information security risks. The XTS-400 design is based on its predecessor, the XTS-300™, the only general-purpose computer system in the world rated at the B3 level by U.S. government security standards.

Trusted applications with high assurance

The Linux®-like programmatic interfaces of the XTS-400’s STOP™ operating system enable developers to port or develop applications easily on the system. These applications reside outside the system’s target of evaluation (TOE), making them easier to accredit, while deriving a high degree of security and integrity from the underlying mandatory protection mechanisms in the TOE.

Several trusted applications available for the XTS-400 have been accredited and are operational. These include trusted guard applications which provide strict control over the automated sharing of information among differently classified networks.

Robust operating system

The XTS-400’s STOP operating system incorporates a high-assurance kernel to enforce the system’s security and integrity policies. The multilevel secure kernel ensures that information, processes, and devices stored and running on the system at different sensitivity levels cannot intermingle in violation of the system’s mandatory security policy. The operating system also provides the capability for regrading objects (changing their security or sensitivity level), ensuring that the security rules defined by the customer are met with high assurance.
