Apple has just released a new document called Leopard Security Configuration (this is a direct link to the 3.4 MB pdf file). The guide provides detailed instructions on how to secure the client version of Leopard (for the server version, see instead 'Mac OS X Server Security Configuration'). It is a very extensive document with more than 200 pages, including a very useful glossary of the different terms that you may want to get familiar with. In particular, the guide covers the numerous new technologies and improvements that were introduced with OS X.5, such as the tagging of files downloaded from the internet, randomization of libraries address space every time you start an application, sandboxing of applications, fine-grained firewall, built-in support for Virtual private network, improved message display to the end-user.
