▶ Execute Bt Support
Intel's Execute Dsable Bt functonalty can prevent certan classes of malcous
"buffer overflow" attacks when combned wth a supportng operatng system. Ths
functonalty allows the processor to classfy areas n memory by where applcaton
code can execute and where t cannot. When a malcous worm attempts to nsert
code n the buffer, the processor dsables code executon, preventng damage or
worm propagaton.
