Comparative study of digital forensic investigation on cyber criminal

Abstract

Digital forensic investigation has undergone tremendous changes in the last decade from initial computers to current mobile devices and storage devices. The significance of digital forensics in the process of prosecuting digital criminals who use digital devices. The process of analysing digital forensic investigations requires a model or framework so that the investigation process can run in more detail and structure. As in previous studies, there is no digital forensic investigation that addresses one standard for all. The digital crimes have increased around the world and have resulted in being developed of survey models that can be escalade to find digital evidence. In some previous studies, there have been many discussions about models or frameworks in investigating a digital forensic case, and these models can be widely used. Some models discuss a detailed process, and some discuss a process in general, this can lead to digital forensic investigators having difficulty choosing the right model in investigating a case. The digital forensic investigation must be carried out effectively, efficiently and structured, with several significant steps that must be considered. Every step and phase must produce documentation that is important in understanding how the investigation process is built. The goal of this paper was to study and compare the digital forensic investigation model. The study also included interpretation and illustration of fundamental concepts used by the framework or model.
