Mike Howard talks about a new piece of technology coming with Windows Vista designed to help fight malware attacks. Called Address Space Layout Randomization (ASLR) - it randomizes where system code is put into memory instead of using the same spot in memory which allows the system to be a target for specific types of malware that looks within memory to find important pieces of system code. In short, with ASLR - system code has 256 spots it can randomly be placed in memory allowing it to become harder to exploit system code in memory. Now, attackers have a 1/256 chance of finding that important piece of code to exploit. | ||

| Why couldn't hypothetical malware create 256 instances, or variations as needed, of itself and determine the most fruitful course of attack to the 256 locations? This is better, but in time it will not be secure enough. |
