EnCase is another tool used for bit stream imaging.
Its core functions are data acquisition, data authentication, data analysis, and logging as well as reporting. This tool can acquire digital evidence from a wide variety of devices by creating a true and accurate bit image copy of the original and authenticating the data acquired (Johansson & Maitra, 2003). One of tools used is Storage Media Archival Recovery Toolkit (SMART).
#Prodiscover basic software
Name three different tools that can be used to create bit-stream backup images and identify their strengths.įor the purpose of forensic examination, special forensic software must be used to undertake bit stream imaging. With the help of ProDiscover Basic, the deleted files can be retrieved for use as evidence. The files that were deleted remain on the disk until a new file is saved to the same physical location, overwriting the old file.

When files are deleted, the space they originally occupied become free and can be used for new files that are saved or files that expand as data is added to them. Usually, the program will be started differently depending on the type of operating system in use. ProDiscover Basic is one of the forensic tools used to write protect any evidence media to ensure that it is not altered (Harvey, 2005). What software or hardware tool must be used in digital media acquisition to protect against inadvertent tainting of evidence by the operating system. The most important thing is to be able to prove that my client requires fair judgment and an opportunity to be heard. As my client’s legal advisor, I have an obligation to protect his or her interests at every stage of the digital forensics investigation till the end (Chow & Shenoi, 2010). This is regardless of whether or not the client in the digital forensics investigation case is on the wrong. If hired to conduct a digital forensics investigation by either side in a criminal or civil action, I will have no choice but to fully represent the interests of my client and defend him or her at whatever cost. If you are hired to conduct a digital forensics investigation by either side in a criminal or civil action, to what do you owe your allegiance? To some extent, corporate investigations can also involve litigation. They are instead governed by internal policies that define expected employee behavior and conduct in the workplace. Private organizations are never governed directly by criminal law or Fourth Amendment issues. While public investigations involve criminal cases and government agencies, corporate investigations deal with private companies, non-law enforcement government agencies, and lawyers. These government agencies range from local, county, and state or provincial police departments to federal regulatory enforcement agencies. Ordinarily, a public investigation involves government agencies that are responsible for criminal investigations and prosecution. What is the primary difference between government run and corporate run high-tech investigations?Ĭomputer forensics can be either a public investigation or a corporate investigation (Nelson, Phillips & Steuart, 2009). The activities in every SOP include collecting evidence, preserving the evidence, analyzing the evidence in a consistent and thorough manner, preparing reports based upon the evidence analyzed by each examiner, and documenting cases complete with notes, worksheets, and other documents used by the examiner to support his or her conclusions. According to Casey (2007), a SOP is a set of steps that should be performed each time a computer is collected or examined. Proper SOPs are essential for digital forensic practitioners to perform investigations that ensure validity, legitimacy, and reliability of digital evidence (Peterson & Shenoi, 2009). Standard operating procedures (SOPs) are usually the ultimate goal of practitioner-based computer forensic models. List five activities that should be in every SOP for digital forensics. What is the purpose of a standard operating procedure (SOP) in digital forensics? You might also think of this as a systematic approach to the investigation. Before logs disappear, digital forensics investigators are required to capture as much information as possible to be presented in court as evidence. The examiner has three basic tasks which include finding, preserving, and preparing evidence (Vacca, 2005). He or she should always gather and preserve evidence according to Federal Rules of Evidence.
A computer forensics examiner may be called upon to provide evidence and advice in a court of law.
