Protecting Critical National Infrastructure Through Collaborative Cyber Situational Awareness

Abstract

The paper describes the implementation of a cyber-security information sharing framework using a real world case study based on providers of critical national infrastructure, specifically air traffic management systems. The paper describes how disparate organisations deal with the unexpected through collaborative cyber situational awareness techniques. Results from the proof of concept demonstration are described, including the effect of using networks, distributed computing techniques and a trust framework to improve interpretation of cyber threats. The conclusions from the demonstration will be presented in light of UK government policy which identified cyber security as a Tier One risk to national security and the benefits or otherwise of adopting a collaborative approach to the problem.
