A number of defensive technologies have been proposed for the prevention of security threats. However, these defensive technologies are implemented independently without cooperation among various network domains. In this paper, different administrative networks are leagued to form a federative network environment called a trusted domain. From the perspective of a network manager, there is a need to integrate diverse technologies into an effective defensive system among mutually trusted domains. An imperative task for security management is to put in place a shared defensive mechanism, or protective shield, for multiple domains. A cooperative approach to provide such a shared defensive system is presented with integration of both intra‐domain and inter‐domain defensive mechanisms. The simulation results show that, through sharing the defensive information, the firewall system can successfully detect and filter the repeated intrusions. Copyright © 2008 John Wiley & Sons, Ltd.
