Fog Computing is one of the edge computing paradigms that envisages being the proximate processing and storage infrastructure for a multitude of IoT appliances. With its dynamic deployability as a medium level cloud service, fog nodes are enabling heterogeneous service provisioning infrastructure that features scalability, interoperability, and adaptability. Out of the various 5G based services possible with the fog computing platforms, security services are imperative but minimally investigated direct live. Thus, in this research, we are focused on launching security services in a fog node with an architecture capable of provisioning on-demand service requests. As the fog nodes are constrained on resources, our intention is to integrate light-weight virtualization technology such as Docker for forming the service provisioning infrastructure. We managed to launch multiple security instances configured to be Intrusion Detection and Prevention Systems (IDPSs) on the fog infrastructure emulated via a Raspberry Pi-4 device. This environment was tested with multiple network flows to validate its feasibility. In our proposed architecture, orchestration strategies performed by the security orchestrator were stated as guidelines for achieving pragmatic, dynamic orchestration with fog in IoT deployments. The results of this research guarantee the possibility of developing an ambient security service model that facilitates IoT devices with enhanced security.

He graduated from the University of Ruhuna, Sri Lanka, in 2010 with honors and received the Lanekassen scholarship for pursuing the Master’s Degree in Information and Communication Technology (ICT) in 2013 from the University of Agder, Norway. Pasika completed his Ph.D. from University College Dublin, Ireland, on improving the security of service migrations of MEC in 2023 and awaits his viva. Prior to his Ph.D., he served as a lecturer attached to the Department of Electrical and Information Engineering, Faculty of Engineering, University of Ruhuna, Sri Lanka from 2014 to 2018. Pasika is experienced in conducting teaching/ instructing/ demonstration work at international universities (UCD-Ireland, BDIC-China). He has authored / co-authored various book chapters, international journals, magazine articles, and conference papers. He is currently conducting collaborative research with researchers at IIT-India, University of Oulu-Finland, and University of Ruhuna-Sri Lanka. He is a member of the research groups of Netslab, PEL based on UCD and University of Oulu. Pasika is focused on enhancing the security measures in 5G and beyond 5G mobile networks, while his main research focus is directed to Federated Learning based security issues and how to overcome them utilizing Blockchain. His additional research directives extend to the areas of lightweight security protocols, formal verification, security and service quality optimization, 5G and MEC integration technologies (SDN, NFV, Blockchain), privacy preservation techniques, and IoT security. In addition to the research work he serves as a reviewer for IEEE IoT journal, IEEE Access, IEEE Communication Magazine, IEEE IoT Magazine, SN Computer Science, and various IEEE hosted conferences and workshops under the IEEE Communication Society (also a member of IEEE ComSoc).
