Security analysis of cyber physical system using digital forensic incident response

There is a great demand for an efficient security tool which can secure IIoT systems from potential adversarial attacks. However, it is challenging to design a suitable security model for IIoT considering the closed, dynamic and distributed architecture. This motivates the researchers to focus more on investigating the role of forensic tools such as DFIR in the designing of security models. A brief analysis of the security issues, challenges and attacks on IIoT systems is presented in this paper with an emphasis of DFIR for the security of ICS, CPS, and SCADA. The security recommendations for IIoT, forensic challenges in SCADA, ICS and CPS are discussed. The study suggests that forensic tools can overcome the drawbacks of conventional security solutions in terms of maintaining the privacy of data while sharing information with other systems. The study discusses different models, overview, comparisons, and summarization of DFIR and intrusion detection systems (IDS)-based techniques for IIoT security. In addition, this review analyzes the challenges and research gaps based on the existing literary works.
