Xcott Craver writes "The 2008 Underhanded C Contest has just opened. Every year, contestants are asked to write a simple, innocent, readable C program that appears to perform an innocent task — but implements some non-obvious evil behavior. This year's challenge: redact blocks from an image, but do it so that the excised pixels can somehow be retrieved. We also have listed the winners of last year's contest, which was to write a simple encryption utility that mysteriously and undetectably fails between 1 percent and 0.1 percent of the time. The winning entry is truly impressive." We discussed the first of these contests in 2005.

Ben Rothke writes "Security policies are like fiber, that is, the kind you eat. Everyone agrees that fiber is good for you, but no one really wants to eat it. So too with information security policies. They are sorely needed, but most users don't go out of their way to comply with them. And in many firms, they are not even trained in what they have to do. But failure to have adequate information security policies can lead to myriad risks for an organization." Keep reading for the rest of Ben's review.

Guillermo brings news that NASA has awarded a contract for the development of the next generation of space suits for future use by astronauts in the Constellation program. The contract calls for two different levels of protection; a flexible, lightweight model for operations inside vehicles and stations, and a tougher, bulkier model built off the first for use on the moon. We've discussed spacesuit design (and what happens without them) in the past. "Suits and support systems will be needed for as many as four astronauts on moon voyages and as many as six space station travelers. For short trips to the moon, the suit design will support a week's worth of moon walks. The system also must be designed to support a significant number of moon walks during potential six-month lunar outpost expeditions. In addition, the spacesuit and support systems will provide contingency spacewalk capability and protection against the launch and landing environment, such as spacecraft cabin leaks."
