随着医院互联网应用的快速发展,针对医院信息系统的网络入侵和攻击日趋严重,传统静态、平面网络安全保障模式已不能满足现代医院信息安全的需要.为保障信息系统安全,结合医院安全体系的实际,以WPDRRC安全模型为理论指导,提出了医院动态网络安全立体模型结构,建设立体、纵深、主动、动态的网络安全防御体系,以提高医院信息系统安全水平.“,”With the rapid development of Internet application in hospital, network intrusion and attack were becoming more and more serious for hospital information system. Traditional static and horizontal network security model is not fit for modern hospital information security. In order to ensure the security of information system, this paper combined the actual situation of hospital safe system, using WPDRRC security model as the theoretical guidance, proposed the dynamic network security model, from the construction of three-dimensional, deep, active, dynamic network security defense system. In order to improve the security level of hospital information system.
