I just posted an explanation of Leopard Security (that’s Mac OS X 10.5 for you non-Apple geeks) up on TidBITS. It’s based on my original blog post here, but expanded and simplified to appeal to a more general audience.

I realize I took some liberties with the explanations of buffer overflows, ASLR, vulnerabilities, and exploits, but I had to tailor the content for a less-security-geek audience.

Check it out, and feel free to flame me here.

I do believe that if everything works as advertised this is a very significant release. There are still some big holes (Quicktime anyone?), but Apple seems to be taking security more seriously than in the past few versions.
