Cray and atsec Achieve CC Security Certification of Cray Linux Environment

Seattle, WA and Austin, TX – Cray Inc. (Nasdaq GM:CRAY) and atsec information security announced today that the Cray Linux Environment (CLE) has been certified by the National Information Assurance Partnership's (NIAP) Common Criteria Evaluation and Validation Scheme as conformant to EAL3+ (enhanced with Flaw Remediation ALC_FLR.1). This evaluation took into consideration a number of new functionalities: the Lustre network file system, Portals high-speed Remote DMA and the application placement scheduler ALPS. The evaluation covers Cray Linux Environment 2.1 running on the Cray XT4 and Cray XT5 computer systems.

This evaluation adds to atsec's impressive record of timely completions of Linux OS evaluations. Since August 2003, atsec has initiated and completed more than 15 Linux evaluations at EAL3+ and EAL4+ on a broad range of hardware platforms. In order to help its customers reach their markets effectively and take the maximum benefit from their evaluation investment, atsec aims at completion of CC projects in conjunction with the company's development schedules.

"The CC certification of CLE continues a long history of Cray support for demanding government and defense computing requirements," said Ian Miller, Cray senior vice president of sales and marketing. "The Linux-based operating system within the CLE suite is designed to run large, complex applications and scale efficiently to more than 240,000 processor cores. CLE provides a rich, highly efficient programming environment that makes it easier to develop scalable applications using the MPI, SHMEM, UPC and OpenMP parallel programming models."

atsec performed the first-ever CC evaluation of a Linux OS in 2003. This evaluation was further proof that the Common Criteria standard is flexible enough to adapt to a variety of software paradigms.

Stephan Mueller, Lead Evaluator for atsec, notes, "Considering the distributed nature of the operating system, the testing was a challenge which was handled efficiently."

Only a handful of companies worldwide are accredited to perform evaluations under more than one national scheme. atsec's Common Criteria labs have been accredited by NIAP CCEVS in the U.S., BSI in Germany and CSEC in Sweden to perform evaluations. This international presence and a large staff of qualified evaluators enable atsec to offer its customers both maximum flexibility and proven expertise and experience in Common Criteria evaluations.
