Win XP and RedHat Linux support based on CPU security protection

Microsoft's Windows XP SP2 and Red Hat's new version of Enterprise Linux3 will support new CPU-based security protections that prevent malicious executable code from being executed.

AMD desktop marketing manager JeffLowe said that improved security features have been included in AMD's 64-bit CPU since last year, but operating system vendors have not added the technology to their operating systems. > Support. This situation will change after Microsoft releases Windows XP SP2 later this year and Red Hat delivers the new enterprise Linux operating system in August.

AMD this new
technology called Enhanced Virus Protection. It is implemented by changing the silicon structure of the processor, which changes the way code is allowed to enter and exit the system memory, thus blocking malicious code.

RedHat is currently developing a new NX (not implemented) technology for Intel's x86 processors and Intel's 64-bit extension technology
. NX prevents the operating system from executing malicious code at the CPU and memory levels, so that malicious code cannot infect a computer or system. NXTechnology
has been used in Intel Itanium CPUs and is now entering x86 CPUs.

RedHat is also developing a security feature called ExecshIEld of the Technology
help separate the program stack and instruction area to prevent executable code is incorrectly run when a buffer overflow.
