An Architecture for National Information Sharing and Alerting System

Protecting critical infrastructure from cyber threats is one of the most important obligations of governments to ensure the national and social security of the society. Developing national cyber situational awareness platform provides a protection of critical infrastructures. In such a way, each infrastructure, independently, generates its own situational awareness and shares it with other infrastructures through a national sharing and alerting center. The national information sharing and alerting center collects cyber information of infrastructures and draws a picture of national situational awareness by examining the potential effects of received threats on other infrastructures and predicting the national cyber status in near future. This paper represents the conceptual architecture for such national sharing system and suggests some brief description of its implementation.
