Apple Adds Memory Randomization To Leopard

Posted by kdawson on from the shuffling-the-wormholes dept.

.mack notes a ZDNet blog outlining some of the security features added to OSX Leopard (10.5). Here's Apple's brief description of all 11 new security features. "Apple has announced plans to add code-scrambling diversity to Mac OS X Leopard, a move aimed at making the operating system more resilient to virus and worm attacks. The security technology, known as ASLR (address space layout randomization), randomly arranges the positions of key data areas to prevent malware authors from predicting target addresses. Another new feature coming in Leopard is Sandboxing (systrace), which limits an application's access to the system by enforcing access policies for system calls."

    All these secure features are welcome, but only if you can switch them off.

    If I'm using a Mac for professional audio work and it's never connected to the internet then it doesn't need such high security. The performance impact of anti-malware software on low latency audio can be pretty vast.

    When I read the word "random" with Mac in the same sentence, why do I envision the iMac Shuffle?
