Critical infrastructures are important assets for everyday life and well-being of the people. People can be affected dramatically if critical infrastructures are vulnerable and not protected against various threats. Given the increasing cybersecurity risks and the large impact that these risks may bring to the critical infrastructures, assessing and improving the cybersecurity capabilities of the service providers and the administrators is crucial for sustainability.
This research aims to provide a questionnaire model for assessing and improving cybersecurity capabilities based on industry standards. Another aim of this research is to provide service providers and the administrators of the critical infrastructures personalized guidance and an implementation plan for cybersecurity capability improvement.
