This paper presents a systematic approach to designing a series of digital forensics instructional materials to address the severe shortage of active learning materials in the digital forensics community. The materials include real-world scenario-based case studies, a set of hands-on problem-driven labs for each case study, and an integrated forensic investigation environment. In this paper, we first clarify some fundamental concepts related to digital forensics, such as digital forensic artifacts, artifact generators, and evidence. We then re-categorize knowledge units of digital forensics based on the artifact generators for measuring the coverage of learning outcomes and topics. Finally, we utilize a real-world cybercrime scenario to demonstrate how knowledge units, digital forensics topics, concepts, artifacts, and investigation tools can be infused into each lab through active learning. The repository of the instructional materials is publicly available on GitHub. It has gained nearly 600 stars and 22k views within several months.

Abstract: Crimes committed using computers are increasing rapidly, posing a challenge to law enforcement. Investigations including cybercrime, terrorism, and civil litigation all make use of digital forensics today. Because of the ever-increasing sophistication of modern technology, forensic investigations of this sort can quickly become difficult and time-consuming. In order to successfully retrieve meaningful digital evidence during such investigations, however, a standard framework for digital forensic professionals to follow must be developed. All appropriate steps that a digital forensic investigation would take should be highlighted by the framework and methodology used to conduct digital forensics. This study provides a system for conducting digital forensic investigations with an emphasis on the forensic aspects of those probes, the tools and procedures employed by examiners, and the significance of hashing in preventing the manipulation of evidence. Digital forensics, as a whole, is still a field that is widely growing along with the continually advancing world of technology. This form of forensics is one that is also growing in importance and necessity due to crimes stemming from digital devices becoming increasingly popular as well. These steady numbers are what have and will continue to drive the field of digital forensics into meeting its full potential on a consistent basis, in both a preventative and recovering manner. However, in order to recognize this potential, it is important to first understand what digital forensics really entails

Considering the ever-growing ubiquity of technology, there is an associated growth in the possibility of digital devices related to a criminal investigation or civil litigation. As the variety of digital devices is increasing, the storage capacity of each is also rising exponentially. Due to the varied and large volumes of data produced, law enforcement agencies (LEAs) worldwide are facing a significant backlog of cases. This has culminated in significant delays in dealing with cases that urgently require digital forensic investigations (DFIs). It is of paramount importance that new research approaches be adopted to address such challenges. This article evaluates the existing set of circumstances surrounding the field of digital forensics (DF). The article provides two important contributions to the field of DF; it identifies and analyses the most important mid- and long-term challenges that need to be considered by LEAs. It also proposes important specific future research directions, the undertaking of which can assist LEAs in adopting a new approach to addressing these challenges.

The digital age has undoubtedly revolutionized the life and work of people. However, this sheen of digital technology remains challenged by the spate of cybercrimes that imperil the privacy and data of the end-users. The alarming rise in cybercrimes has become a major concern for cyber specialists. In this grim context, digital forensics has emerged as a boon for cyber specialists because it has proven to be an effective means for investigating cyber-attacks. This chapter reviews the existing tools and approaches in the field of digital forensics in cybersecurity. This chapter also discusses the current challenges and problems that are faced by a forensic investigator. In addition, it enlists the different categories of digital forensics. The study concludes by underlining the importance and the need for extensive research in digital forensic tools.

The research work presented in this paper aims to review Digital Forensics (DF) techniques and trends. As computer technology advances day by day, the chances of data being misused and tampered with are also growing daily. The advancement in technology results in various cyber-attacks on computers and mobile devices. DF plays a vital role in the investigation and prevention of cyber-attacks. DF can be used to find the shreds of evidence and prevent attacks from happening in the future. Earlier presented reviews highlighted specific issues in DF only. This paper explores deeply DF issues by highlighting domain-specific issues and possible helpful areas for DF. This article highlights the investigation process framework and related approaches for the digital investigation process. The cognitive and human factors that affect the DF process are also presented to strengthen the investigation process. Nowadays, many DF tools are available in the industry that helps in DF investigation. A comparative analysis of the four DF tools is also presented. Finally DF performance is discussed. The submitted work may help the researchers go deeper into DF and apply the best tools and models according to their requirements
