1.5.2 Ensure XD/NX support is enabled

Information

Enabling any feature that can protect against buffer overflow attacks enhances the security of the system.

Solution

On 32 bit systems install a kernel with PAE support, no installation is required on 64 bit systems-If necessary configure your bootloader to load the new kernel and reboot the system.You may need to enable NX or XD support in your bios. Notes- Ensure your system supports the XD or NX bit and has PAE support before implementing
this recommendation as this may prevent it from booting if these are not supported by your hardware.
