Haven’t had the time to read it yet, but Stephen de Vries has posted a whitepaper on securing Mac OS X: “This guide is aimed at users in environments requiring stronger security controls in an operating system, making full use of the protection features offered in OS X. It would also be of use to system administrators wishing to enforce an organisation wide desktop security policy for Mac OS X.

Couldn’t hurt anyone choosing to lock down their OS X machine further, eh?
