Comprehensive Security Overview and Key Features of Apple Snow Leopard 10.6

The release on Friday of Apple's Mac OS X 10.6, known as "Snow Leopard," has elicited criticism from security companies, which may have business to lose if Apple's latest operating system reduces interest in third-party security software.

Mac OS X 10.6 also includes hardware-based execution control for heap memory, stronger checksums for preventing memory corruption attacks, and antivirus capabilities.
