Digital Forensics Corporation: Digital Forensics Service .

This discussion contains two parts. Please ensure that you address each of the points in each part. Part 1 - Discuss the implications of full volume encryption and what forensic examiners must be mindful of when dealing with such technology on a "live machine" or one that is powered off. Discuss the difference between imaging the physical disk versus a volume. When imaging a "live machine," are their differences between imaging the physical disk v. logical volume in terms of being able to view logical data within the forensic image in your forensic software? Part 2 - Assume that you have just arrived at the scene of a search warrant, and you have been asked by the investigator to assess a Windows Surface device, which is running Windows 8 Enterprise. The user account screen is in a locked state, and the desktop is obviously not in view.

PART 1
The full volume encryption or the full disk encryption is a very strong encryption and
it is used in digital forensics. The influence of full volume encryption on digital forensics is
important (Vincze, 2016). This encryption can adversely influence the capability to develop
copy of the hard drive or to recover information those are intelligible to a forensic
investigation.
The integration of this strong encryption into the operating systems is developing
challenges for the examiners of forensics thereby, preventing the examiners from any of the
evidences those are digital from a system. This is because the strong encryption cannot be
circumvented without the use of key, the examiners of forensics may not be able to view the
data when the system is shut down and they must decide whether to execute a live acquisition
of forensics (Mehta & Rathod, 2018). Therefore, the examiners must take some precautions
when they are handling such strong encryption as when they require the credentials in order
to access the data and if these are not available then the examiner need to get a forensic image
of a system that is live while the contents are in the state those are not encrypted.
The difference between imaging a physical disk and imaging a volume disk are it is a
bit to bit copy of the whole hard disk or the partition and the imaging the volume disk is the
copy of the files those are referenced in the system of files (Stich et al.,2016). These are just
the files that are on the hard drive. If the physical image is obtained then the examiners have
everything. If the physical image is executed via processing software of forensics, it will find
out the files those are deleted and many more.
When imaging a disk that is live, there are differences between imaging a physical
disk and imaging a logical volume (Ham & James, 2020). If the examiners obtain the
physical image then they can access the logical data and the deleted files. Imaging the logical

volume means that the imaging is done of the files those are present on the hard drive of the
system.
PART 2
The information above states is to access the windows surface device that is running
of Windows 8. The user account is locked and the desktop cannot be seen and an app called
mSecure is running on the system. The computer system and the mobile devices need to be
searched and the stuffs of the systems are bit locked.
The first step is to open the account of the user and then view the desktop to see that
any files those are present on the system. The stuffs are encrypted by the bitlocker. Therefore,
the task is to unlock the bitlocker and access the files. In order to unlock the bitlocker,
password is to be produced but it is with the user so, password is to be cracked using the
password cracking tools such as ophcrack (Harbawi & Varol, 2017). Then the files can be
easily accessed. The files are to be searched for the clues in order to proceed with the
investigation. In order to get the evidence, a software known as FTK imager is used in order
to assess the electronic evidence those are present in the electronic files. FTK imager is an
imaging and data preview tool in order to evaluate the electronic evidence. After the evidence
has been collected from the files, the image of the physical disk need to taken if some clues
are present in the files that have been deleted by the criminal (Du, Le-Khac & Scanlon,
2017). A logical image also need to taken in order to evaluate the files in the hard drive.
The full volume encryption is used in order to lock the machine and the hard drive so
that the forensic officer cannot enter the machine and evaluate the files and the evidences
those are present in the electronic (Hasan, Awais & Shah, 2018). The criminal may have used
some software like Encrypt it or TrueEncrypt in order to encrypt the hard drive. The criminal
can also use full volume or full disk encryption and it becomes very difficult for the

investigating or the forensic officers to crack this encryption, as this encryption is very
strong.
