Blockchain-Based Security Configuration Management for ICT Systems

The world has become increasingly dependent on large-scale and distributed information communication technology (ICT) infrastructures systems in sectors such as energy, transport, banking, healthcare, water supply, digital services, while their protection is considered of paramount importance already drawn remarkable attention from governments key industry players. Establishing common approaches by leveraging existing frameworks cyber security practices for improving the postures those one major objectives ensuring an adequate level avoiding detrimental effects disruptions society citizens. Configuration management (CM) establishing maintaining integrity consistency a system its elements with regard to function, performance, status technical physical attributes, it contributes desirable posture throughout lifecycle system. This study addresses CM, considering corresponding frameworks, standards, best practices, proposes permissioned blockchain-based approach, that inherits benefits blockchain ensures systems’ configuration across complete products services underlying model mapping integrating CM functions. Furthermore, this briefly presents challenges application models smart-contract-based role-based access control mechanism, addition presenting operating concept based brief but real-life requirements organizational management.
