In a connection-oriented system, shared firewall protection provides the identical stage of protection against on its own firewall failures as dedicated firewall protection, with potentially superior network exploitation. This paper lists the constraints of firewall placement strategies and proposes a heuristic routing algorithm for communal security provisioning. Simulations be conducted to confirm the algorithm and to balance network utilization of shared firewall protection to that of devoted fortification. A shared firewall protection system provides end-to-end firewalls in wired or wireless networks. To prevent from intruded traffic, a firewall may be shared by another firewall, or so-called relay firewall. The shared firewall has the same source and destination as the original or main firewall.
