The National Security Agency isn’t all about listening in on other people’s conversations or being the object of insanely paranoid fantasies. The NSA also has an Information Assurance mission, protecting guvmint computers from hackers, spies, and this guy. Now taxpayers can take advantage of the billions of dollars they have paid in to keep the NSA running… the agency has released a pretty good guide to securing home computers (PDF file) with information for Windows and Mac users. Unfortunately, it is a little bit on the techie side – you can’t just email it grandma and assume she’s good to go, but it does provide a great checklist to help you (and your colleagues) batten down those cyber-hatches. Worth a read.
