Intel Virtualization Technology is a
set of platform features that

support virtualization of platform
hardware and multiple software
environments. When enabled, it

workloads on one physical server
system.
Intel's Execute Disable Bit
functionality can help prevent
certain classes of malicious buffer
Enabled
overflow attacks when combined
with a supporting operating
system. Execute Disable Bit allows
the processor to classify areas in
memory by where application code
can execute and where it
cannot. When a malicious worm
Disabled
attempts to insert code in the
buffer, the processor disables code
execution, preventing damage and
worm propagation.
