Using VProbes for intrusion detection

[摘要] Many current intrusion detection systems (IDSes) are vulnerable to intruders because they are running under the same operating system (OS) as a potential attacker. Since an attacker will often be attempting to co-opt the OS, this leaves the IDS vulnerable to subversion by the attacker. While some systems escape this threat, they typically do so by running the OS inside a modified hypervisor. This risks of adding new bugs that reduce the correctness or security of the hypervisor, and may make it harder to incorporate upstream improvements. VMware has a technology called VProbes that allows setting breakpoints, examining machine state, and inspecting memory from a VM host. This thesis introduces VProbe Instrumentation for VM Intrusion Detection (VIVID), which makes subverting the instrumentation much harder while still allowing the use of an off-the-shelf hypervisor.
