How can virtualization affect computer forensics

There are two common types of investigative analysis involved in digital forensics: live and dead. The former happens while a machine is running and often focuses on things like open files, running processes, network connections, and volatile malware.

In many cases, systems need to continue running for as long as possible to provide the insight authorities need to find evidence. This reduces the possibility of source contamination and makes investigating static data from a system easier. Both approaches have inherent strengths in the way they approach and retrieve evidence in the form of data—but they also have a few weakness to keep in mind.

That means information must be gathered by locating and looking at the internal data structures of the in-guest application programming interface API. This inability to get what is needed is known as the semantic gap problem, and it characterizes the difference between two descriptions of the same thing—in this case, the data on the screen.

In other words, it can get lost in translation. But fear not, there are some solutions available. This cross-platform virtualization software can be installed on existing Intel or AMD-based computers, regardless of their OS.

It helps users simultaneously run multiple OSes on existing computers, essentially creating a special environment where multiple virtual machines can run on a single physical machine.

This tools helps with learning, testing, and getting the most out of computer performance. With this type of server virtualization, multiple virtual machines can run on the same physical server by installing a hypervisor on the main device, each of which runs its own OS. This means many OSs can run on one physical server, thereby allowing virtual machines to share resources such as RAM. The most recent version, vSphere 6.

As law enforcement and legal entities continue to realize just how valuable IT professionals can be in digital forensics, the field has grown into a valuable tool for protecting public and private entities.

As well as government and national security. The ability to track the digital movements during an attack has provided physical evidence in criminal cases and allowed authorities to uncover the forces behind many, many cyber-crimes. The success of these efforts is based on a the integrity of five main steps:. A new tab for your requested boot camp pricing will open in 5 seconds. If it doesn't open, click here.

What is Virtual System Forensics?

Alternatively, a virtual machine with VM player software on a thumb drive could be used to mount a new OS without rebooting.

The user could then do whatever he or she wanted to on the host computer, unplug the thumb drive when finished, reboot the computer if necessary , and leave without a trace. Although it might be possible to track the activity back to the IP address of the physical computer, this scenario will leave no traces of the activity on the hard drive; few, if any, traces in the registry; and, upon rebooting, no trace in memory.

Learn what kind of traces VMs leave behind. Dust off your imaging skills. Start the guest OS in a forensically sound environment and perform a live image of the VM as you would a live image on any other computer.

Employ an application, such as VMware Disk Mount, that can mount the VM as a physical drive, which can then be imaged. Farmer, D. Addison-Wesley, Reading Google Scholar. Dorn, G. Kornblum, J.
