A processor can be instructed to designate regions of memory as non-executable. This means that the memory can be used to store reference data to be read and written, but that the processor cannot treat the contents of the memory as program code to be directly executed. Intel calls this capability in their newer processors XD for “eXecute Disable” and AMD refers to it as NX for “No eXecute.” AMD's marketing materials also sometimes refer to this capability by the term EVP for Enhanced Virus Protection.
As a hardware capability of modern processors this addition is important, but its use depends entirely upon support from the operating system. So when Microsoft introduced support for this into their operating systems, they termed it Hardware DEP for Data Execution Prevention. Support for hardware DEP was introduced into the 32-bit versions of Windows XP with Service Pack 2, into Windows 2003 Server with Service Pack 1, and has always been present in Windows Vista. Hardware DEP does …
