Harris Corp, which has committed to PowerPC RISC for future generations of its Night Hawk 88000-based real-time computers, is now offering Secure/Power Unix, an implementation of its Unix with security features, and is making it available on IBM Corp’s RS/6000s as well as its own Night Hawks. The company claims Secure/Power Unix to be the first and only standards-based B2-level environment available for the RS/6000 and the only one targeted for compliance with the PowerOpen Environment. Harris notes that the offering is also the first Unix System V.4 for the RS/6000. It is also Posix-compliant and meets X/Open Co Ltd portability standards. It is based on System V.4.2 MP and its B2-level security capabilities as defined by the National Computer Security Centre is the highest level of security for a full Unix implementation. Control and protection of sensitive information is achieved through the use of data access controls, auditing and labelling. Available immediately from Harris and IBM Federal Systems, it is supported on the RS/6000 Models 220, 550 and 590, and Night Hawk 5000 Series with support for some PowerPC systems set for early 1995.
