I found sort of a linux propaganda site but their list of security tips is pretty good and straight forward, although not technically inspired!

For some real Linux propaganda told in genuine 'granny story telling' gibberish, give this rather long article a read!

Generally I'm against propaganda and more for technical facts but considering the web is full of propaganda about windows, reading some about linux can be fun and even if it is just fiction or a user experience rewritten in story form, they are probably more true then much of the windows propaganda out there!

With all due respect, but IMHO calling it "Top Linux security advisory" is a wee bit *over* the top. Maybe it *does* help newbies but basically it's a recap of whatever has been said already: no new info, no refreshing POV or whatever else remarkable.
