EDB - Execute Disable Bit functionality
An Enterprise Security technology from Intel - can help prevent certain classes of malicious buffer overflow attacks when combined with a supporting operating system.
Windows is supposed to use this feature, however, if you search for: "execute disable bit vista" you get mostly references to XP and SP2. If the feature were to one that is widely used you wpuld think that Microsoft would promote its use.
No clear indication whether the Linux kernel can use it.
Like the Intel "Virtualization Technology", the operation of this feature depends on too much "sleeping with the enemy"!

- AMD call this MX - while Intel also use XD bit, for eXecute Disable - aparently they have the same function
- Intel to incorporate Execute Disable Bit technology into new processors - Techspot from 2004 - seems like it has been around for a while - maybe I have just noticed it!
