A firewall is a security guard placed at the point of entry between a private network and the outside Internet such that all incoming and outgoing packets have to pass through it. The function of a firewall is to examine every incoming or outgoing packet. Here the paper aims to implement ACO (Ant Colony Optimization) in the design process thereby allowing better filtering of the packets. The design of the firewall will be based on matching the rules and remembering the rules accessed by laying down pheromone.
