Execute Disable Bit

The Execute Disable Bit allows memory to be marked as non-executable when combined with a supporting operating system. If code attempts to run in non-executable memory, the processor raises an error to the operating system. This feature can prevent some classes of viruses or worms that utilize buffer overrun vulnerabilities and can, thus, help improve the overall security of the system.
