Address Space Layout Randomization(ASLR) -defense

mechanism that makes it harder for malicious code to exploit system functions is Address

Space Layout Randomization (ASLR). Whenever a Windows Vista computer is turned on or

rebooted, ASLR randomly assigns executable operating system code (such as.EXE programs

and dynamic link libraries or.DLLs) to one of 256 possible locations in memory. This makes

it harder for an attacker to locate and take advantage of any functionality inside these executables.
