A multidisciplinary digital forensic investigation process model

Worldwide usage of mobile smart devices has increased dramatically over the past two decades. The popularity of these devices has grown as a result of their increased processing power, storage capacity, and memory; they can now hold enormous amounts of both personal and private business data. In addition to the consideration of mobile devices, the scope of any forensic investigation has also grown to include cloud environments. Previously, we proposed a working model that can improve the effectiveness and efficiency of an investigation in a multidisciplinary environment. The study presented herein, however, evaluates a straw man model derived from current practice models to identify the required improvements. The study also proposes a new improved process model known as a multidisciplinary digital forensic investigation process model.
