Abstract: This paper evaluates firewalls, their importance in protecting networks and their functions such as performance, efficiency and security. The intercourse between the security and performance efficiency is created through different scenarios and the relationship between security and performance in firewalls is evaluated. Several scenarios were evaluated through simulations using OPNET to show the effects of firewalls on network performance.
