Critical Entities Resilience Assessment (CERA) to small-scale disasters

Abstract

Since 2022, there has been a significant increase in the importance of critical entities in terms of critical infrastructure protection. The adoption of the Critical Entities Resilience Directive must in EU member states ensure not only the protection of critical infrastructure, but also a sufficient resilience level of the entities themselves. This directive obliges critical entities to take measures to increase their resilience but does not provide any methodological support. A necessary starting point for fulfilling this obligation is knowledge of the current state of critical entities resilience to small-scale disasters. The results of the resilience assessment will then enable critical entities to identify vulnerabilities on the basis of which adequate technical, security and organisational measures can be defined. Therefore, this article presents an entirely new semi-quantitative method, CERA, which has been developed for the comprehensive assessment of entity and infrastructure resilience of critical entities. At the core of this method is a procedure that allows critical entities to self-assess their internal resilience through individual factors, which are defined in detail in this article. In order to facilitate the assessment process, the authors of the article have created the CERA Support Tool, which is supplementary material to this article. The Results section of the article also includes a presentation of a practical application example of the proposed procedure.Ministry of the Interior of the Czech Republic [VK01030014]; VSB - Technical University in Ostrava [SP2024/039]Ministerstvo Vnitra České Republiky, (VK01030014, SP2024/039
