Abstract:   (267 Views)
In response to the critical need for protecting critical infrastructure and managing cyber crises, this article introduces an operational framework for establishing national-level Cyber Situational Awareness (Cyber SA). The Information Sharing and Alerting System (ISAS), as the central authority, integrates the cyber situational awareness postures of Information Sharing and Analysis Centers (ISACs) across infrastructures, forming a unified international Cyber SA posture. Our framework offers a quantifiable and coherent metric for national-level Cyber SA, based on cybersecurity risk, determined by the impact of cyber threats on sector-specific macro missions and their interdependencies. Application to cyberattack scenarios demonstrates the framework's accuracy in reflecting situational dynamics and assessing the relative significance of different sectors and ISACs. In summary, our framework simplifies national Cyber SA measurement, enhances cyber crisis management and decision-making, and systematically addresses interdependencies among critical infrastructures.
Keywords: cyber situational awareness at national level, macro missions, national cyber SA framework, ISAC traffic, Critical infrastructure.
