Towards a Cooperative Defense Model Against Network Security Attacks

It is widely acknowledged that internet security issues can be handled better through cooperation rather than competition. We introduce a game theoretic cooperative model against network security attacks, where users form coalitions and invest in joint protection. We analyze coalition formation in three canonical security games described in a previous work by Grossklags et al. Our findings reveal that the success of cooperative security efforts depends on the nature of the attack and the attitude of the defenders.
