HP says a broad range of its computer hardware running Red Hat Enterprise Linux 5 has been examined and certified as compliant under the international Common Criteria product-evaluation programme.
HP's Integrity, ProLiant, and BladeSystem platforms, as well as workstations and desktops, have received the Evaluation Assurance Level 4 (EAL4+) Common Criteria security certification for Red Hat Enterprise Linux 5, the version of the operating system released last March.
EAL4+ is the highest level of security that unmodified commercial software can achieve. Higher rankings to level 7 typically involve highly customised systems designed for maximum-security government purposes.
However, Erik Lillestolen, programme manager for open source and Linux at HP, noted that the Zen-based technology for virtualization that's part of Red Hat Linux 5, was not tested under the Common Criteria programme.
"Nobody has included the virtualization technology yet," he added about the Common Criteria security-evaluation program, which is backed by several countries as a multinational testing regimen.
