PurposeGathering, analyzing and securing electronic data from various digital devices for use in legal or investigative procedures is the key process of computer forensics. Information retrieved from servers, hard drives, cellphones, tablets and other devices is all included in this. This article tackles the challenging problem of how to prioritize different kinds of computer forensics and figure out which kind is most useful in cases of cybercrime, fraud, theft of intellectual property, harassment and espionage.Design/methodology/approachTherefore, we first introduce enhanced versions of Hamacher power aggregation operators (AOs) within the framework of bipolar complex fuzzy (BCF) sets. These include BCF Hamacher power averaging (BCFHPA), BCF Hamacher power-weighted averaging (BCFHPWA), BCF Hamacher power-ordered weighted averaging (BCFHPOWA), BCF Hamacher power geometric (BCFHPG), BCF Hamacher power-weighted geometric (BCFHPWG) and BCF Hamacher power-ordered-weighted geometric (BCFHPOWG) operators. Employing the devised AOs, we devise a technique of decision-making (DM) for dealing with DM dilemmas with the BCF set (BCFS).FindingsWe prioritize different types of computer forensic by taking artificial data in a numerical example and getting the finest computer forensic. Further, by this example, we reveal the applicability of the proposed theory. This work provides a more elaborate and versatile procedure for classifying computer forensics with dual aspects of criteria and extra fuzzy information. It allows for better and less biased DM in the more intricate digital investigations, which may lead to better DM and time-saving in real-life forensic scenarios. To demonstrate the significance and impression of the devised operators and techniques of DM, they are compared with existing ones.Originality/valueThis research is the first to combine Hamacher and power AOs in BCFS for computer forensics DM. It presents new operators and a DM approach that is not encountered in the existing literature and is specifically designed to deal with the challenges and risks associated with the classification of computer forensics. The framework’s capacity to accommodate bipolar criteria and extra fuzzy information is a major development in the field of digital forensics and decision science.

Formalising investigative decision making in digital forensics: Proposing the Digital Evidence Reporting and Decision Support (DERDS) framework

Digital forensics has been utilized in computer crime investigation for last thirty years. It has evolved and progressed around the technical revolutions, and is now facing yet another new era due to the emergence of cloud computing. Cloud computing is a new computing model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services). The innovative nature of cloud computing has created unique challenges in the field of digital forensics. In this research paper, we present detail study to investigate the forensic issues in cloud computing and provide possible solutions, guidelines, including existing case studies. The basics of traditional digital forensics and cloud computing are also discussed.

Digital Forensics has become an indispensable tool in contemporary cybercrime investigations, which ensures systematic identification, collection, preservation, and presentation of electronic evidence in a legally admissible manner. As cybercrimes continue to escalate, investigative authorities are required to operate across multiple digital domains, including personal devices, mobile platforms, cloud infrastructures, and transnational communication networks, with strict adherence to the law. Digital forensics is important not only because it can recover the deleted or concealed data, but also because it ensures that the evidence remains authentic and untouched throughout the investigation. Due to its dual emphasis on both technology and law, it effectively bridges the gap between technical accuracy and legal accountability. Despite being so advanced in the contemporary world, the field of digital forensics still faces persistent challenges. The extensive reliance on data encryption, rapid technological innovations, and the issue of complex jurisdiction in cross-border investigations complicate and hamper the effective use of digital forensics. Moreover, the escalation of data generated in the digital age raises concerns about privacy, transparency, and the timely administration of justice. Addressing these concerns requires some advanced and well-developed standardized forensic frameworks, legal protocols, and greater international cooperation to harmonize investigative procedures. This paper shall dwell upon the continuous evolution of the role of digital forensics in cybercrimes in the contemporary world. It shall particular ly focus on the foundations, challenges, evidentiary value, and implications for law enforcement and global cybersecurity. It shall also emphasize the strengthening of digital forensics so that harmonious international relations and global cybersecurity can be achieved.

Internet of Things (IoT) is increasingly permeating peoples' lives, gradually revolutionizing our way of life. Due to the tight connection between people and IoT, now civil and criminal investigations or internal probes must take IoT into account. From the forensic perspective, the IoT environment contains a rich set of artifacts that could benefit investigations, while the forensic investigation in IoT paradigm may have to alter to accommodate characteristics of IoT. Therefore, in this article, we analyze the impact of IoT on digital forensics and systematize the research efforts made by previous researchers from 2010 to 2018. We sketch the landscape of IoT forensics and examine the state of IoT forensics under a 3-D framework. The 3-D framework consists of a temporal dimension, a spatial dimension, and a technical dimension. The temporal dimension walks through the standard digital forensic process while the spatial dimension explores where to identify sources of evidence in IoT environment. These two dimensions attempt to provide principles and guidelines for standardizing digital investigations in the context of IoT. The technical dimension guides a way to the exploration of tools and techniques to ensure the enforcement of digital forensics in the ever-evolving IoT environment. Put together, we present a holistic overview of digital forensics in IoT. We also highlight open issues and outline promising suggestions to inspire future study.

Medical Internet of Things (MIoT) Forensics is an important subject that has received little attention. With the advancement of the Internet of Things (IoT), Machine Learning (ML), and Artificial Intelligence (AI) applications, a large amount of data gets generated with increased complexity. Consequently, it gives rise to cyber-attacks and data theft. The consequences of these malicious activities can be life-threatening. Therefore, organizations must identify these threats to implement proactive and reactive measures. Digital Forensics of medical devices focuses on reactive measures to generate evidence of unprecedented events presented in court. Digital forensics, in combination with ML, might aid in the development of a secure MIoT system that can detect cyber-attacks and provide evidence for the legal process. Implementing digital forensics in medical systems is challenging, given their complex functioning. This paper presents a novel methodology for developing a forensic-ready MIoT system with two distinct approaches: an intrusion detection system and modeling of the physiological data. In addition, we cover various digital forensic processes for MIoT systems to log evidence of malicious activity at various system levels. This research highlights the importance of digital forensics for MIoT privacy assurance.

This research aims to explore the influence of digital forensics education and training on the quality of handling cyber crime cases. With the increasing complexity of cybercrime, it is important for law enforcement to have adequate skills in digital forensics. The research method used is qualitative with a case study approach in several law enforcement agencies. The research results show that effective education and training can improve investigators' abilities in identifying, collecting and analyzing digital evidence, thereby improving the quality of handling cyber crime cases. In addition, collaboration between investigators and digital forensic experts has been proven to increase the effectiveness of investigations. However, challenges such as limited resources and legal understanding remain obstacles that need to be overcome. Therefore, recommendations to improve education and training programs in the field of digital forensics are very necessary to face the growing threat of cybercrime.

Digital forensics field faces new challenges with emerging technologies. Virtualization is one of the significant challenges in the field of digital forensics. Virtual Machines (VM) have many advantages either it be an optimum utilization of hardware resources or cost saving for organizations. Traditional forensics’ tools are not competent enough to analyze the virtual machines as they only support for physical machines, to overcome this challenge Virtual Machine Introspection technologies were developed to perform forensic investigation of virtual machines. Until now, we were dealing with persistent virtual machines; these are created once and used many times. We have extreme version of virtual machine and that is disposable virtual machine. However, the disposable virtual machine once created and are used one time, it vanish from the system without leaving behind any significant traces or artifacts for digital investigator. The purpose of this paper is to discuss various disposable virtualiza-tion technologies available and challenges posed by them on the digital forensics investigation process and provided some future directions to overcome these challenges.

Computer virtualization is not a new technology, it has become increasingly important because of the many advantages it offers to businesses and individuals to reduce costs, while introducing new challenges to the field of digital forensics. As virtualization continues to be adopted by more and more companies every year, malware and hacker attacks are going to have an increasing effect on virtualized systems. Therefore, the increasing growth of virtualization has created the need for a new generation of computer forensic tools and techniques to analyze these compromised systems. Because of the rapid growth of virtualization, new techniques to interact with virtual systems have been developed. Some of these techniques reduce the limitations of traditional forensics tools abilities to analyze the virtual system. Virtual Machine Introspection (VMI) is one of these techniques that have formed the basis for a number of novel approaches in the fields of cyber security and digital forensics. This paper explores how VMI improves traditional digital forensics to overcome its downfalls when used to investigate virtual machines, especially during a live analysis of the machine.

In the case of digital forensic investigations, the potential digital evidence captured, the analysis, interpretation, and attribution must ultimately be presented in the form of expert reports, depositions, and testimony in any legal proceedings. If the presentation and interpretation of the potential digital evidence is conducted correctly, it is much easier and useful in apprehending the attacker and stands a much greater chance of being admissible in the event of a prosecution. Wrongly presented and interpreted potential digital evidence data might create loopholes for perpetrators to exploit, thus, making it hard to convict and prosecute them. Existing digital forensic investigation process models have provided guidelines for identifying and preserving potential digital evidence captured from a crime scene. However, the extent to which such potential digital evidence may be admissible in a court of law remains a challenge to investigators. This is backed up by the fact that there are currently no standardised guidelines for even presenting the most common representations of digital forensic evidence. Therefore, in the authors' opinion, methodologies and specifications need to be developed in the field of digital forensics with the ability to effectively enhance the potential digital evidence presentation and interpretation in any legal proceedings. In this paper, therefore, we present a step-by-step framework in an attempt to propose high-level guidelines for enhancing the potential digital evidence presentation in any legal proceedings. Such a framework will be helpful to digital forensic experts, for example, in structuring investigation findings as well as in identifying relevant patterns of events to be incorporated during the presentation of potential digital evidence. The framework will also assist law enforcement agencies, for example, to determine, with less effort, the validity, weight and admissibility of any potential digital evidence presented. However, it should be noted that the purpose of this paper is not to replace any of the extensive and known evidence presentation principles, but serves as a survey of the state of the art of the research area while proposing harmonised and high-level guidelines for enhancing the presentation of potential digital evidence in legal proceedings.

The evolution of the Information Age has necessitated and facilitated the relatively new field of digital forensics. As a largely practitioner-driven field, there is no clearly defined research agenda to promote top-down research in related areas so that the evolution can be more solidly based on research findings. This paper builds on previously published topical research agendas for digital forensics and introduces a preliminary research hierarchy for legal issues associated with digital forensics. Topics discussed include constitutional law, property law, contract law, tort law, cybercrime, criminal procedure, evidence law, and cyber war. In addition some special associated problems and overarching areas are identified for consideration and for future research.
