NSA's Mac-hardening tips

The National Security Agency has developed a set of Security
Configuration Guidelines for Apple Computer's OS X 10.5 (Leopard)
operating system, according to an InformationWeek report.

"[These] tips assume that the reader is starting with a default
installation of Mac OS X 10.5 (Leopard)," NSA notes in its
introduction to the guidelines, and adds that they "may not
translate gracefully for previous versions."

The guidelines cover securing users' home folder permissions,
physical security, disabling IPv6, AirPort and other unnecessary
services when not needed, disabling Setuid and Setgid binaries,
configuring and using both firewalls, among other suggestions,
InformationWeek reports.
