Recent processors in the x86 family support the ability to prevent code execution on a per memory page basis. Other processors, such as Itanium and POWER, have included such support since inception and the standard kernel for those platforms supports the feature. Extra steps must be taken to ensure that this protection is enabled, particularly on 32-bit x86 systems. This ability can help prevent exploitation of buffer overflow vulnerabilities and should be activated whenever possible. Generically and on AMD processors, this ability is called No Execute (NX), while on Intel processors it is called Execute Disable (XD).
