Cyber Forensics and Comparative Analysis of Digital Forensic Investigation Frameworks

With industrial revolution 4.0, automation foster communications between digital devices around the globe which involves several digital devices including cyber physical system devices, IoT devices, mobile devices, storage devices and network devices or even PCs as digital evidence; increasing the number of cybercrime rate. This brings us to question a necessity for advanced Digital Forensics Investigation Framework (DFIF) for the effective prosecution of digital crime in court of law; such that the framework should preserve integrity of evidence throughout steps while in process. Our paper is descriptive in nature that surveys recent trends of cybercrime attacks and explored associated Cyber Forensics. In addition, we have mapped process and output produced by different phase in the DFIF that have been examined from previously proposed frameworks and represented a comparative mapping of all frameworks. The mapping process results in optimized investigation process.
