Abstract:

The Internet has become important since information is now stored in digital form and is transported both within and between organisations in large amounts through computer networks. Nevertheless, there are those individuals or groups of people who utilise the Internet to harm other businesses because they can remain relatively anonymous. To prosecute such criminals, forensic practitioners have to follow a well-defined procedure to convict responsible cyber-criminals in a court of law. Log files provide significant digital evidence in computer networks when tracing cyber-criminals. Network log

Abstract:

Computer crimes have become very complex in terms of investigation and prosecution. This is mainly because forensic investigations are based on artifacts left oncomputers and other digital devices. In recent times, perpetrators of computer crimesare getting abreast of the digital forensics dynamics hence, capacitated to use someanti-forensics measures and techniques to obfuscate the investigation processes.Incases where such techniques are employed, it becomes extremely difficult, expensive and time consuming to carry out an effective investigation.

Abstract:

Digital forensics is the science concerned with discovering, preserving, and analyzing evidence on digital devices. The intent is to be able to determine what events have taken place, when they occurred, who performed them, and how they were performed. In order for an investigation to be effective, it must exhibit several characteristics. The results produced must be reliable, or else the theory of events based on the results will be flawed. The investigation must be comprehensive, meaning that it must analyze all targets which may contain evidence of forensic interest. Since any investi

Abstract:

Continuous professional development has been looked at in many professions over the years, most notably in primary and secondary education and in the medical fields. With digital forensics being cast into the limelight due to the rapid advancements in technology, academic institutions have added courses to address the void created by the boom in the industry. Little research has been done to address the issues that have now become apparent concerning continued learning in this field. The purpose of this research was to investigate the kinds of frameworks and methods used in other professions,

In computer forensics, digital evidence related to time is both important and complex.

However, they deliberately abuse their authorised (i.e. insider) access in order to contravene an organisation’s policies or to commit computer crimes.

Abstract:

Aujourd'hui, la manipulation d'images à des fins non éthiques est courante, notamment sur les réseaux sociaux et dans la publicité. Les utilisateurs malveillants peuvent par exemple créer des images synthétiques convaincantes pour tromper le public ou dissimuler des messages dans des images numériques, posant des risques pour la sécurité nationale. Les chercheurs en analyse forensique d'image travaillent donc avec les forces de l'ordre pour détecter ces manipulations. Les méthodes d'analyse forensique les plus avancées utilisent notamment des réseaux neuronaux convolutifs pour les détecter. Ce

Abstract:

Digital Forensics (DF) is defined as the ensemble of methods, tools and techniques used to collect, preserve and analyse digital data originating from any type of digital media involved in an incident with the purpose of extracting valid evidence for a court of law. DF investigations are usually performed as a response to a digital crime and, as such, they are termed Reactive Digital Forensic (RDF). An RDF investigation takes the traditional (or post-mortem) approach of investigating digital crimes after incidents have occurred. This involves identifying, preserving, collecting, analyzi

D.Phil.(Computer Science)<br>We are living in an increasingly complex world in which much of society is dependent on technology and its various offshoots and incarnations (Rogers & Siegfried, 2004). There is ample evidence of the influence of technology on our daily lives. We communicate via e-mail, use chat groups to interact and conduct business by using e-commerce. People relate each other’s existence to a presence on Facebook. The convergence of the products, systems and services of information technology is changing the way of living. The latest smart and cell phones have cameras, applica

Abstract:

The increasing usage of databases in the storage of critical and sensitive information in many organizations has led to an increase in the rate at which databases are exploited in computer crimes. Databases are often manipulated to facilitate crimes and as such are usually of interest during many investigations as useful information relevant to the investigation can be found therein. A branch of digital forensics that deals with the identification, preservation, analysis and presentation of digital evidence from databases is known as database forensics. Despite the large amount of informati

Abstract:

Recent decades have seen a significant increase in the importance of the field of digital forensics as a result of the rapid development of information and communication technologies and their penetration into every corner of our lives and society. Furthermore, information security incidents are not only becoming more versatile every year, but are also growing in number, thus emphasising the importance of digital forensic investigations. Performing a digital forensic investigation requires a standardised and formalised process in order to ensure the admissibility of digital evidence, as

Abstract:

The problem encountered by the researcher was that the South African Police Service Cyber-Crimes Unit is experiencing problems in seizing computer evidence. The following problems were identified by the researcher in practice: evidence is destroyed or lost because of mishandling by investigators; computer evidence is often not obtained or recognised, due to a lack of knowledge and skills on the part of investigators to properly seize computer evidence; difficulties to establish authenticity and initiate a chain of custody for the seized evidence; current training that is offered is unable to c

Abstract:

There is a growing global recognition as to the importance of outlawing malicious computer related acts in a timely manner, yet few organisations have the legal and technical resources necessary to address the complexities of adapting criminal statutes to cyberspace. Literature reviewed in this study suggests that a coordinated, public-private partnership to produce a model approach can help reduce potential dangers arising from the inadvertent creation of cybercrime havens. It is against this backdrop that the study seeks to develop a digital forensic readiness model (DFRM) using a coordinate

Abstract:

Indiana University-Purdue University Indianapolis (IUPUI)<br>In the last few decades, forensic science has played a significant role in bringing criminals to justice. Shoe and tire track impressions found at the crime scene are important pieces of evidence since the marks and cracks on them can be uniquely tied to a person or vehicle respectively. We have designed a device that can generate a highly accurate 3-Dimensional (3D) map of an impression without disturbing the evidence. The device uses lasers to detect the changes in depth and hence it is crucial to accurately detect the position of

Abstract:

This research thesis explores technical, legal and organisational challenges of digital evidence and the implications of their inter-relationships for responses to criminal, illegal and inappropriate on-line behaviours. From a forensic computing perspective the solutions to these challenges have tended to focus on discrete sets of technical, legal or organisational issues individually. Lack of understanding of the inter-relationships between these issues is inhibiting the development of integrated and coordinated solutions that can effectively balance requirements for the generation of
