I have been thinking of ideas to stop many file attacks on Unix systems. 
When you find rootkits or other attack files on many Unix systems they will often try to hide their tracks by using 
filenames such as '...' and '/tmp/.X11-unix' etc.
I wish to write a kernel module (for linux initially) that will prevent such attacks. The kernel module in pseudo 
code:

This would help against a few of them, but just until they start using
some name not in the bad names list.
For example, suckit uses something in /usr/share/locale. If it's tagged
as bad, one could just name it something else. Hiding a file isn't
really hard after all, at least if you are hiding from someone not
searching for it.
