Developing a Novel Digital Forensics Readiness Framework for Wireless Medical Networks Using Specialised Logging

Abstract

Wireless Medical Networks (WMNs) have always been a vital component for the treatment and management of chronic diseases. However, the data generated by these networks keeps growing and has become a potential target for criminals seeking to capitalise on its sensitivity and value. Wireless networks also happen to be more vulnerable to attacks compared to wired networks. In the event of such attacks, it becomes really difficult to conduct a digital Forensics investigation. This paper investigates and suggests a proactive approach of digital forensics readiness within wireless medical networks by suggesting specialised monitoring and logging mechanisms. The research first identifies threats to wireless medical networks. It then undertakes a trajectory of a systematic review of previously proposed digital forensics frameworks and identifies challenges. Finally, it proposes a conceptual framework for Digital Forensics Readiness (DFR) for wireless medical networks. The paper, therefore, makes a novel contribution to the field of digital forensics. It suggests a more streamlined, robust, and decentralised framework that is partially underpinned by blockchain technology at the evidence management layer. The framework contributes to the enforcement of evidential data integrity whilst also securing wireless medical networks.
