Research purpose: develop, evaluate and validate the use of a decision support system (DSS) in managing cyber risks in critical infrastructures (CI).
Research objectives: review the use of DSS in risk management in the context of CIs; identify the elements and peculiar requirements when developing the concept of using a DSS in a context and environment where safety requirement is critical; evaluate the factors and their impact upon perceived efficiency of information systems; develop and validate a model, metric intelligent formal system and application to evaluate cyber security maturity in CI; evaluate and propose recommendations on the cyber security legal framework in CI in the Republic of Moldova.
The scientific novelty and originality: an innovative DSS concept, an evaluation model of cybersecurity maturity and DSS efficiency, a knowledge base, a metric intelligent formal system, and a software prototype implementing this system. The prototype also enables the application of the cybersecurity assessment model and presents the results through an easy-to-use interface and easy-to-understand metrics.
The main scientific problem solved: ensuring CI cyber security through an innovative solution based on an DSS concept developed as a module and intended to identify, classify and manage cyber risks in СI.
The theoretical significance: a developed concept of DSS for cybersecurity maturity assessment. The concept is supplemented by an applicable model for external assessment or self-assessment of CI cybersecurity. Additionally, a metric intelligent formal system and a software prototype implementing the selected evaluation process were developed.
The applicative value: a model for DSS efficiency evaluation, a metric intelligent formal system and a software prototype.
The implementation of results: the DSS model has been awarded the Bronze Medal at CadetINOVA 2021 - Innovation and Scientific Research Exhibition, Bronze medal at the International Exhibition of Inventions and Innovations „Traian Vuia” 2022, has been positively evaluated and assessed as applicable for the CI domain by the Slovenian Nuclear Security Administration, National Institute of Metrology from Moldova, Technical University of Moldova, as well as included in the master's degree curriculum in „Nuclear and Radiological Safety” within Technical University of Moldova.
