The National Security Agency [NSA] has a set of guides for securing systems and software.
Included in the list of guides is a 3.1 MB PDF document describing how to secure Apple's Mac OS X Panther (10.3.x). [ Thanx to and via Bill Bumgarner ]
Das PDF hat 109 Seiten – UNCLASSIFIED – manches davon ist sehr trivial, aber dennoch recht interessant. Durchaus lesenswert.
