Google’s ChromeOS, at first glance, is something of a touchdown for operating system security. It’s probably the most secure operating system in the world (at the cost of some limited functionality). Unfortunately, ChromeOS isn’t a panacea, and serious security concerns about the platform remain. First, though, the good news: ChromeOS (the stripped-down linux operating system that runs on inexpensive Chrome-branded netbooks) has a bunch of really nice features for security-conscious users.
