“This week, however, Linux was also awarded with CC security certification, and as one might expect, this announcement greeted with cheers from the open source community. There’s just one catch: Linux got a lower security rating than Windows 2000 did last year.” Read it at WinInformant. Update: The WinInformant article is a little slanted in its reporting, since the ratings discussed have little to do with how secure either OS is in real-world use. Keep in mind that to achieve the higher rating, the computer is not allowed to be connected to any network, since network-connected computers are inherently vulnerable. A CNN article shoots a little straighter on the subject. The certification is not a contest to see which is more secure, simply a test to see if the OS matches a certain objective set of criteria. You have to severely cripple a modern OS to make it meet government high security certification.
