▶ CPU Configuration
▶ Active Processor Cores
This setting specifies the number of active processor cores.
▶ Execute Disable Bit
Intel’s Execute Disable Bit functionality can prevent certain classes of mali-
cious “buffer overflow” attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory by
where application code can execute and where it cannot. When a malicious
worm attempts to insert code in the buffer, the processor disables code execu -
tion, preventing damage or worm propagation.
