Relations of Network Characteristics and Protection Strategies against Attacks

[[abstract]]The real-world networks are large and complex entities and there are many studies on mathematical models in simulating real-network structure. This paper proposed a platform to simulate protection strategies against attacks in order to gain better understanding of the relation between network characteristics and information security. We set up several attack and protection strategies in three network models. The attacker carries out attack and the defender uses limited resources to improve the defenses of network. For a given cost of attacks, we will analyze the impacts of network characteristics and show their effectiveness of protection.[[sponsorship]]IEEE Taipei Section; National Science Council; Ministry of Education; Tamkang University; Asia University; Providence University; The University of Aizu; Lanzhou University[[conferencetype]]國際[[conferencetkucampus]]淡水校園[[conferencedate]]20091203~20091205[[booktype]]紙本[[iscallforpapers]]Y[[conferencelocation]]Tamsui, Taipei, Taiwa
