Microsoft Secures Vista with Random Memory Placement

Microsoft has begun testing a new security technology in Windows Vista Beta 2. Called ASLR, or Address Space Layout Randomization, the technology loads system code into different locations in memory when the computer is booted. This helps prevent exploit code from calling system functions because the exploit code won’t know exactly which memory location to call. In Windows Vista Beta 2 an application could be in any of 256 locations making it harder to find. This is by no means a complete protection from insecure code, but it is a start and makes it harder to exploit Windows.
