For the first time, The Guardian is detailing how a tech company works with the National Security Agency to share user information under the NSA's PRISM program. Unfortunately, that tech company happens to be Microsoft, the one that makes the operating system used on 92 percent of computers in the world.
The tone of the report (and Microsoft's statement about it) contrasts significantly with what the company said when PRISM was revealed. The Guardian, using documents obtained from NSA leaker Edward Snowden, paints Microsoft as a compliant partner in creating windows and doors in their software for the government to access.
Before we get to the mechanics, we'll answer the obvious: Which Microsoft products are covered? Primarily the web-based ones. There are three specific Microsoft services that NSA has privileged access to: Outlook, SkyDrive, and Skype.
