"There's an operating system and application in every package, every one with its own configuration and patch status and you have no idea what's in there or who's going to maintain it or what the long-term risk is going to be," MacDonald says. If the hacker owns the hypervisor, he/she owns all data traversing the hypervisor and is in a position to sample, redirect, or spoof anything. Hypervisors help in secure isolation of multiple virtual machines running on single physical hardware. The overarching issue with virtual servers is responsibility, MacDonald says. The hypervisor operates like an operating system and could require patching. "We try to treat the VMs in exactly the same way we do physical machines—with system scans, antivirus, and everything else.

It addresses the security issues faced by the components … Thus, operating systems offer a level of abstraction above the hardware, on which multiple processes can run concurrently. In many ways virtual machines are more secure than standalone servers, if only because they are more isolated and because they depend on a single host server, which makes the physical security issue much simpler than if each were on a separate piece of hardware, he says. The section discusses several topics related to virtualization security issues, including VMs image management, virtual machines monitor, network virtualization, mobility, issues in virtual machine, and malware as seen in Table 5. If attackers gain access to your host-level or VMware vCenter server, this opens doors for them to access other important VMs, or even create a user account with admin rights that could be used over a long period of time to collect or destroy sensitive company data. No matter their age, interests, or ability, these gifts will put a smile on any hacker's face this holiday season.

Disable Virtualization-based Security If you no longer use virtualization-based security (VBS) with a virtual machine, you can disable VBS. The National Security Agency has taken that concern not only to heart, but to software development labs, coming up with a virtual-server management scheme called NetTop that requires a configuration preventing VMs running on the same machine from interfering with one another. Virtualized environments remove that restriction and create a one-to-many attack scenario: attack the host, own the guests-or even attack one guest, possibly own them all. Multi-tenancy is a needed requirement to be provided in. By If, or when, attacks focused on virtual machines become readily available, the attacker potentially only has to spend time attacking one virtual machine, which could lead to compromising other virtual machines over a closed network, and eventually escaping the virtual VMM environment and accessing the host. The decoupling of physical and logical states gives virtualization inherent security benefits.
