Is defenseless Mac OS Snow Leopard?

Since the release of Snow Leopard operating system, it did not take much time, but critics have found it a disadvantage. Charlie Miller (Charlie Miller), two-time winner of the hacker competition Pwn2own and author of The Mac Hacker's Handbook, He believesThat Apple could try and better protect the new OS. In the version of Mac OS 10.6 embedded technology that provides a random location address space (ASLR) and Data Execution Prevention technology (DEP), but that, in his opinion, enough.

According to Miller, in Snow Leopard using the same technology ASLR as in version 10.5 operating system - Leopard. It has already been compromised two years ago, but has not been improved. Full support for ASLR in the "Snow Leopard" operating system would do practically invulnerable. Moreover, Miller in an interview with ComputerWorld claims that Snow Leopard is more secure than Leopard, but is less secure than Windows 7. "Now write a working exploit for Windows is more complicated than for the Mac », - says Charlie. Well, that was held QuickTime modernization, fixed all major bugs in the player. In its updated version did not load an exploit that vulnerability is successfully used by the player before.

But here's the paradox: Miller believes Mac OS X sufficiently secure system and sees no need for any antivirus software.
