Wired is reporting that Microsoft is releasing the most secure version of Windows XP ever created, but only if you are the US Air Force. "The Air Force persuaded Microsoft CEO Steve Ballmer to provide it with a secure Windows configuration that saved the service about $100 million in contract costs and countless hours of maintenance. At a congressional hearing this week on cybersecurity, Alan Paller, research director of the Sans Institute, shared the story as an template for how the government could use its massive purchasing power to get companies to produce more secure products. And those could eventually be available to the rest of us. Security experts have been arguing for this "trickle-down" model for years. But rather than wield its buying power for the greater good, the government has long wimped out and taken whatever vendors served them. If the Air Force case is a good judge, however, things might be changing."
