http://www.cisecurity.org/ CIS has released a benchmark for Freebsd , If you have never seen this before its worth a look even if you don't use Freebsd as they have the same for linux, win(2000-xp pro), solaris, hp-ux. A great way to see the little things you may have missed. You get a great little pdf with the tool also

Have fun tightening permissions and disabling..
