with the latest virtualization softwares and the multi threading technology, how will the the intel multi cores help for a hack-proof environment?
I don't think Intel multi-core or hyper-threading technologies provideany contributionto system security. Rather, they provide increased parallelism which greatly improves processing power.
System security is handled on a coarse-grained level by the VMM which ensures isolation between VMs, and on the fine-grained level by each OS which ensures isolation between processes running within a VM and the enforcement of user privilege levels.
Intel VT-x provides features related to VMM traps and privilege levels. Take a look at the journal articles in
for more information.
