Virtual Machines Introspection techniques for virtualization security in Cloud

As Cloud virtualization becomes increasingly mainstream, different security tools and techniques for virtualization security are evolving. The virtual machine monitor (VMM) also called hypervisor offers us the ability to completely mediate interactions between the host software and the underlying hardware. Virtual machine introspection (VMI) tools inspect a VM from the VMM level to assess what’s happening on its inside. Hence, implementing security software or monitoring software for security tools, inside VMM will protect and isolate them from untrusted processes inside a VM, providing a high-confidence barrier between the security software and attacker’s malicious code.
