? Abstract?Digital forensic investigations has become an important field in this era due to the raise of cybercrimes. Therefore, most governments and companies found the urgent need to invest more in research related to digital forensic investigations. To perform digital forensic investigations covering extraction, analysis, and reporting of digital evidences, new methods and techniques are required. One of these methods used when applying digital forensics on a Windows operating system, is PowerShell. While PowerShell is mainly used to configure, manage and administrate the Windows operating system and other installed programs, this paper will also show that it could be used to collect forensic evidences from a Windows operating system.

Information is being stored and exchanged using these different digital devices or machines. Such level of usage and the people?s dependency on these devices, lead to the exposure of a new type of threat and crime. Such threats and crimes could be named ?cyber threats? and ?cybercrimes?, respectively. Threats that are targeting such devices require a special kind handling. Crimes that are done, whether against or using such devices will need to be investigated differently in order to reach the proper evidence to either incriminate the suspect or refute him/her. Digital forensic investigation defined as ?the use of scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation and presentation of digital evidence derived from digital sources for the purpose of facilitating or furthering the reconstruction of events found to be criminal, or helping to anticipate unauthorized actions shown to be disruptive to planned operations? [1]. It?s mainly related to criminal and unauthorized actions …show more content…
However, collecting artifacts only not sufficient without analysis by connecting each artifact with other according to the relation between them. Afterward, all artifacts should order according to the time to reach the final solution of the case. Therefore, timeline is one of the important things in the investigation and should be considered in the final report as it will include full story of the case. Thus, J. Atkinson didn?t forget to include forensic timeline convertor to PowerForensics which convert artifacts to timeline style and can export it to different formats. Fig. 6 present an example of an exported timeline in comma separated value
Digital forensics can be broken down into three phases; acquisition, analysis, and presentation. The acquisition phase is where the data is saved in a way that it can be analyzed latter. Because it is not known at the time what data is or is not valuable to the case, all data is saved. In the analysis phase, the data is examined and placed into three major categories; inculpatory, exculpatory, or signs of evidence tampering (Carrier, 2002). Tools are used in this phase that are able to analyze for the list directory contents, deleted files, and recover the deleted files. In the presentation phase, the data has been documented in a way that it can undergo a peer review. When deleted files are recovered, the analyst must show how they were found because they were ...

Forensics investigations that require the analyzation and processing of digital evidence can be influenced both positively and negatively by a number of outside sources. In this paper, we will explore how physical security plays a role in forensics investigations activities. We will start by examining how physical and environmental security might impact the forensics investigation process. Next, we will discuss the role that physical and logical security zones play in supporting effective forensics activities. We will illustrate how centralized and decentralized physical and environmental security affects the forensics professional’s approach toward the investigation. Lastly, we will evaluate some potential areas of risk related to the physical security of our case study organization, Widget Factory, identified in Attachment 1.
Technologies are advancing in today's world where more information is being generated, stored and distributed through digital gadgets. This requires investigators and forensic expert to increase the use of digital evidence gathering as a tool to fight against cyber-crime (International competition network, n.d.).

One of the most important aspects of studying a history of a place is why that place came into existence in the first place. The FBI's Regional Computer Forensics Laboratories are perhaps not a terribly well-known entity within the general public, yet they play an essential part in both our justice system, and our everyday lives. So this begs the question, why would a laboratory centered strictly around computers, even more specifically the forensics around computers, come to be in an age where certainly all major government establishments have, and are familiar with, computers and the technology associated within them. These are a few of the questions that will be answered throughout this research paper, along with an analysis of where they are today, and where it appears the future of these labs will take them.
A Crime Scene Investigator must first approach the crime scene as if it is their only opportunity to protect and retrieve physical evidence. There are special technics and tools that crime scene investigators use to retrieve, preserve, and label all types of evidence (for lists of Crime Scene Equipment see Appendix A). The general protocol for crime scene investigation, processing, and analysis involves five basic steps: interview, examine, photograph, sketch and process (Berg, 2008). When looking at the crime scene it needs to be looked at with fresh eyes and without a prejudiced opinion of what happened, how it happened, or who might have done it. A conclusion may be based solely on the evidence and so an investigators integrity and judgment, gathering the evidence, maybe what stands between a conviction and a dis...
Technology has opened new encounters and opportunities for the criminal justice system. There are so many new practices of criminal activity, such as computer crimes. There are different types of computer crimes that many people become victims of every day. Computer crime is any crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target ("Computer Crime: Chapter 2: What Are the Crimes?", n.d.). Crimes such as data diddling, pump and dump, social engineering and spoofing are computer crimes. Even though these crimes are difficult by privacy issues, the new technology has made investigations and prosecutions well organized and effective. Though views are different on the pros and cons of specific technological changes in the criminal justice system, there is an agreement the system has changed affectedly ("Effects of Technology in Criminal Justice | eHow", n.d.).
The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of computer crimes, law enforcement agencies use computer forensic to investigate these offenses. Actually, computer crimes are governed by specific laws and dealt with through conducting a computer forensic investigation (Easttom & Taylor, 2011, p.337). Notably, a computer forensic investigation is usually carried out through the use of computer forensic tools, which help in collection of evidence based on the specific offense.
What did they do ? Before we talk about it any further, we have to know some definitions that we use in digital forensics and digital evidence, not only two of them but the others too. This chapter will explain about it . Before we talk about it any further, we have to know the definition of what we are talking about. In the introduction we already know what digital forensic and digital evidence shortly are. In this chapter, we will more explore what they are, and some state that we found when we search about digital forensic and digital evidence. Computer forensics is a broad field and applied to the handling of crimes related to information technology. The goal of computer forensic is to securing and analyzing digital
Digital Evidence is electronic data, materials, objects, property, documents, or records that are presented in court to prove or disprove allegations made against an arrestee. It takes the form of electronic data or information stored in bits and bytes on magnetic media. The examples of devices that can contain digital evidence include; cellular phones or similar all in one devices, pagers, digital voice recorders.
Digital Forensic is described as “ a forensic science encompassing the recovery and investigation of materials found in digital devices “ (“Introduction to Digital Forensics,” 2011). The objective of digital forensics is to implement a well-structured investigation while preserving a documented chain of custody and evidence custody form to know what really occurred on digital devices and who was accountable for it.
These types of crimes have become a matter of importance for the consumers as well the business firms because it involves large eviction of the amount in terms of money. In these types of crimes, computer and Internet are the primary factor (Spinello, 2000). A high percentage of population is using computers in the Australia, United States as well as other developed nations. These people are much more connected with the world by the use of internet. They are using the computer for fun, business, e-commerce, e-marketing, etc.; thus, it has become an essential part of life and daily routine (Wall, 2008).
Computer crime or Cyber Crime is defined as any type of crime that involves or regards a computer or computer network. Cyber Crime mainly means that the computer may be used as a tool in the commission of the crime or the computer may be the main target of the criminal’s crime. The rapid growth of technology and gadgets as well as the further de...
