Apple released its Security Configuration Guide for Mac OS X 10.5 "Leopard" on Monday, a 240-page document that describes ways for sophisticated Mac users to further secure their systems.
The manual includes an overview of the Mac OS X's security architecture and advice on hardening the operating system against external attackers as well as locking down the system to protect against unauthorized access by people with physical access to the system. The instructions make extensive use of the command line, and Apple warns readers that only technically-adept users should use the guide.
"Certain instructions in the guides are complex, and deviation could result in serious adverse effects on the computer and its security," Apple said in an introduction to the Security Configuration Guides. "The guides should only be used by experienced Mac OS X users, and any changes made to your settings should be thoroughly tested."
In the past few years, Apple has increasingly focused on security as researchers and hackers scrutinized its products more closely. Bug finders have targeted the company's Mac OS X operating system, its iPhone mobile phone and the Safari Web browser. In March, security researcher Charlie Miller used a vulnerability in the Safari browser to compromise the MacBook Air at the PWN2OWN competition in Vancouver, B.C.
The guide is available for download from Apple's Web site.
