A Dynamic Cyber Security Situational Awareness Framework for Healthcare ICT Infrastructures

The healthcare sectors have experienced a massive technical evolution over the past decade by integration of medical devices with IT at both physical and cyber level for a critical Health Care Information Infrastructure (HCII). HCII provides huge benefits for the health care service delivery but evolving digital interconnectivity among medical and IT devices has also changed the threat landscape. In particular, systems are now more exposed to the cyber-attacks due to sensitivity and criticality of patient health care information and accessibility of medical devices and this pose any potential disruption of healthcare service delivery. There is a need to enhance security and resilience of HCII. In this paper, we present a Cyber Security Situational Awareness Framework that aims to improve the security and resilience of the overall HCII. The framework aims to develop a novel dynamic Situational Awareness approach on the health care ecosystem. We consider bio inspired Swarm Intelligence and its inherent features with the main principles of the Risk and Privacy assessment and management and Incident handling to ensure security and resilience of healthcare service delivery.
