Well, I know that this is a bit of a shameless plug, but I also think that it’ll help out anyone who tasked with securing OS X in any way or form. I’ve just finished working with a bunch of guys on putting this checklist together for the SANS S.C.O.R.E section on their website, so take a look and I hope it helps someone out. It covers all the basic parts of securing OS X, and is more than sufficient to get a lot of people started, and to end up with a much more secure OS X installation.
