Digital Forensic Readiness of Information Systems: A cost-benefit variable analysis

Abstract

Despite the increasing amount of research on the pre-incident side within a digital forensic investigation, little steps have been taken towards assessing the effectiveness of such a plan in terms of cost effectiveness. This research paper lays the foundations of a cost-benefit variable analysis within a digital forensic readiness context by defining a cost-benefit relationship effect model. We collect novel, primary data from organisations and institutions that implement a digital forensic readiness plan to identify cost variables of each measure and threat, and benefit variables of each measure to be taken. We conduct data analysis to portray that specific cost variables have a significant effect on specific benefit variables and present the results of the data collection process amongst organisations and institutions applying a digital forensic readiness plan. Lastly, we produce hypotheses testing results and determine the validity between each cost-benefit relationship.
