<jats:p>Network security is also facing major challenges. On the one hand, network security assessment can dynamically reflect the state of network security and reveal potential threats. On the other hand, network security assessment is the basis of network security management, it is also the prerequisite for building a reliable and secure network. This paper proposes a multi-level network security measurement model, which divides the network into a network environment layer and a network attack and defense layer. The network environment layer considers the network hardware security and the reliability of a network topology. The network attack and defense layer mainly examines the security status of the network from the perspective of network attack and defense. The model comprehensively evaluates and measures the network from different layers of the network, and conducts experiments. The result of experiment proves that the model can effectively assess the security of the network.</jats:p>
