The U.S. agency best known for eavesdropping on telephone calls had a hand in the development of Microsoft's Vista operating system, Microsoft confirmed Tuesday. The National Security Agency (NSA) stepped in to help Microsoft develop a configuration of its next-generation operating system that would meet U.S. Department of Defense (DOD) requirements, said NSA Spokesman Ken White. This is not the first time the secretive agency has been brought in to consult with private industry on operating system security, White said, but it is the first time the NSA has worked with a vendor prior to the release of an operating system.
By getting involved early in the process, the NSA helped Microsoft ensure that it was delivering a product that was both secure and compatible with existing government software, he said. "This allows us to ensure that the off-the-shelf security configuration that the DOD customer receives is at a level that meets our standards," White said. "It just makes a lot more sense to be involved up-front, than it does to have the tail wag the dog." The NSA's involvement in Vista was first reported Tuesday by The Washington Post . The NSA has provided guidance on how best to secure Microsoft's Windows XP and Windows 2000 operating systems in the past. The agency is also credited with reviewing the Vista Security Guide published on Microsoft's Web site.
