Abstract: Firewalls are devices or programs that control the flow of network traffic between the outside internet and the private network. The model of stateful firewalls consists of two sections: a stateful section and a stateless section. The stateful section checks whether the firewall accepts a packet previously that may affect the fate of the current packet. We issue queries to analyze the function of their firewalls. In this paper, we introduce how to describe a stateful firewall query and how to process a stateful firewall query. We present methods for optimizing stateful firewall decision diagrams to efficiently perform SFDD-based firewall Query Processing Algorithm. Our experimental results show that our SFDD-based firewall Query Processing Algorithm is more efficient than the traditional Rule-Based stateful Firewall Query Processing.
