    If you have to worry about things like APT... you've got quite a problem and no any widespread OS would save you easily on its own. And even exotic OS could be investigated by such a powerful adversary. Security is funny thing. Most dangerous time is when you feel yourself safe.

Isn't Linux too late to the party? Multi-layered security?


    You are thinking address randomisation that was added in Vista. This did not add stack randomisation of the stack offset that this is doing. ASLR and DEP really comes into the LInux kernel sooner than Windows. Linux basic DEP is called NX that even old added to Linux.

    Grsecurity patchset provided some more advanced stuff than Microsoft Windows offered now those features are turning up as mainline features. This is a feature that just been adding to the LInux kernel that OS X and Windows don't have if you are lucky they will get it in another 2 to 3 years..

    Doesn't Windows have this since XP?
