I am trying to secure a linux Ubuntu box and I am no expert. I am following guidance available on the net.

Section 15.2 discusses world-writable files. The following command

find / -type f -perm -o+w -exec ls -l {} \;

returns a long list of files all located under /proc.

My question is: is this a good or a bad thing regarding security? Should I do something about these files?

Thanks!

find / -type f -perm -o+w -ls will produce mostly the same output but in a shorter way. I hope you appreciate it. :) –  user unknown Mar 5 '11 at 3:47

The short answer is there's nothing you can do about it, so don't worry about it.

Files under /proc are generated automatically, and aren't "real" files. They are pointers to various OS settings and resources. You'll probably notice they all have a length of 0 as well.

You can safely ignore these.

In your case, don't care about files in /proc and /sys.
