Evaluation of the Effectiveness Of Physical Protection Systems with Consideration of its Cyber-Resilience

The importance of security in the modern, dynamically changing world seems to be understood across the globe. Different types of organizations, both from the public and the private sector, are creating strategies and investing large amounts of funds to implement Physical Protection Systems (PPS) in order to protect their assets. It appears relatively obvious that assessment of the effectiveness of PPS is important and required. Moreover, the result of the assessment should be reliable and cover as much as possible current threats, including those that are coming from cyberspace. In this paper, we propose a new approach to evaluating PPS. Our proposition as a starting point is using well-known EASI (Estimate of Adversary Sequence Interruption) methodology but reinforced with methods aiming to cover the cybersecurity of PPS considering all potential adversary paths.
