Relations of network characteristics and protection strategies against attacks

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 [1] [2]. 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.
