Advanced Server approved by DOD The U.S. Department of Defense Information Systems Agency has certified Linux distributor Red Hat’s Advanced Server operating system as a “Common Operating Environment,” meaning the server product meets the agency’s software security and interoperability specification.The certification, announced by Red Hat officials Tuesday, is for Red Hat’s top-of-the-line Linux Advanced Server running on IBM’s eServerxSeries330 hardware. The Red Hat server is the first Linux product to receive this certification, according to Red Hat. The Common Operating Environment (COE) certification is designed to provide common IT architecture within the Department of Defense, as a way to promote interoperability among the department’s computer systems.The certification allows the Defense Department to “achieve the required level of conformance so vital to joint warfare by embracing the self-governance standards created by the Linux community,” Matt Mleziva, program director of Defense Information Infrastructure for the U.S. Air Force, said in a Red Hat press release. According to Red Hat, this Defense Department certification is “broadly recognized” within the U.S. government as a rigorous standard. The certification puts the server software on the Defense Department’s approved list for mission-critical operating systems, said Red Hat, based in Raleigh, N.C.The COE certification “expels yet another myth about the enterprise readiness of open source software,” said Michael Tiemann, chief technical officer at Red Hat, in the press release.The COE certification is mandated by the Defense Department Joint Technical Architecture for operating systems to be considered for deployment on command-and-control, computer, communications, and intelligence systems. A handful of other operating systems are also certified under the COE: Sun Microsystems’ Solaris, Microsoft’s Windows NT, IBM’s AIX, and Hewlett-Packard’s HP-UX.
