There are all kinds of tidbits in the document. The guide spans basic 'hardware' security practices as well as the new security features introduced in Leopard, such as library randomization and sandboxing. These instructions should only be used by experienced Mac OS X users, and should be followed by thorough testing.
Some instructions in this guide are complex, and deviation could cause serious adverse effects on the computer and its security.
