Trends, Challenges and Opportunities of Engaging Digital Forensics for Cybercrime Investigations

Abstract

The use of digital forensic tools and techniques has continued to evolve as the security community makes efforts to stay ahead and mitigate cyber crimes. These tools and techniques are assisting cybersecurity experts and law enforcement in identifying fraudsters and protecting data by utilizing techniques such as digital traces left by data processing and storage. This paper identifies the peculiarities of digital forensics as a field of study, explores trends, challenges and opportunities presented by digital forensic tools in investigating cyber crimes. We carried out a systematic literature review of applicable tools and techniques. Our research identified challenges affecting the use of digital forensics in investigating cybercrime, and capture comprehensively the pulse of the domain. Recommendations were made that digital forensics lack a unified formal representation of standardized procedures and knowledge for analyzing and gathering digital artifacts. This inevitably causes incompatibility and conflict within various digital forensics tools. This leads to errors in the interpretation and analysis of digital artifacts due to lack of standardized or formalized procedure for analyzing, preserving, and collecting digital evidence is absent.
