Trailrunner7 writes "As applications have become more and more complex in recent years and Web browsers have evolved into operating systems unto themselves, the task of securing desktop environments has become increasingly difficult. And while there's been quite a bit of innovation on Windows security, advances in Unix security have been less common of late. But now, a group of researchers from Google and the University of Cambridge in England have developed a new sandboxing framework called Capsicum, designed specifically to provide better security capabilities on Unix and Unix-derived systems (PDF). Capsicum is the work of four researchers at Cambridge and the framework extends the POSIX API and introduces a number of new Unix primitives that are meant to isolate applications and users and handle rights delegation in a better way. The research, done by Robert N.M. Watson, Ben Laurie, Kris Kennaway and Jonathan Anderson, was supported by Google, and the researchers have added some of the new Capsicum features to a version of Google's Chromium browser in order to demonstrate the functionality."
