Leopard's anti-virus secret: scrambled eggs

| 5 Comments | No TrackBacks
OS 10.5's got lotsa new stuff, particularly in the field of se curity. In fact, Apple's got about 11 new security features in corporated into Leopard. Perhaps the most interesting of the lot is the security technology called ASLR, or Address Space Layout Randomization, whose basic c oncept is to randomly and periodically jumble up the locations of key data area s, thus preventing malware attacks that rely on the established addresses of vu lnerable data, or predicting their locations - it's a bit like scrambling eggs. This code-scrambling technology makes the system less prone to virus and worm a ttacks, and mixes things up for a more lively and exciting time. One more reaso n to get Leopard on Friday.

As a Mac user who has pre-ordered Leopard, I am waiting with bated breath to re
ceive Leopard.

However, Microsoft can actually brag that it beat Apple to the scene with ASLR,
as ASLR is a feature of Windows Vista.

Thankyou Mike - i'm not the only one who realised this article's ENTIRE HEADLIN
E is a complete fabrication - how is something a 'secret' if windows *and* linu
x use it already?

Oh that's right... Mac Headline=readers=page hits.

Cheap, guys. Very cheap

Wow, thanks for the post, that's some good info. I didn't know that Leopard had
ASLR...I just wonder HOW much of a difference it would have made years ago for
Windows. It's nice to see Apple taking a lead incorporating it into Mac OS bef
ore viruses start coming our way.

Great post! Just wanted to let you know you have a new regular reader - me!
