Understanding the Importance of System Security

Before we can reasonably discuss ways to make your Mac OS X machine more secure, it's important to understand why you should care and what you're facing.

You might be wondering, “Why bother with security?” You've never cared about securing your Mac before. In fact, prior to Mac OS X, security has rarely been an issue for a Mac owner. However, as a Unix-based operating system, Mac OS X brings with it not only the advantages of a Unix operating system—it also brings the disadvantages. Unfortunately, one of those disadvantages is security, which has always been a problem for networked, multitasking operating systems. This is unsettling at the beginning, but the simple fact is that nothing can be done to make any network-connected Unix machine (Mac OS X or otherwise) completely secure. To paraphrase one system administrator's feeling about securing a Unix machine, “I'd pull the plug and the network, put the machine in a safe, fill the safe with concrete, lock it, and drop it in the middle of Hudson Bay—and even then I wouldn't be sure.”
