海上计算机网络防御策略的精细化技术研究

Research on detailed technologies of defensive tactics of seaborne computer network

海洋运输和船舶工业的发展促使船舶向自动化、智能化方向发展。由于当前船舶均接入内部局域网络及海上互联网,其计算机网络系统易受到网络病毒攻击。为提高计算机网络防御策略的精细化技术,本文首先建立船舶网络系统,根据计算机病毒传播的SIS模型,提出基于主机和基于网络的精细化防御策略,提高了船舶计算机网络系统的安全性。

The development of marine transportation and ship industry has boosted the shipment towards automation and intelligence. Due to the fact that ships are connected to local network and seaborne internet, the computer network are vulnerable to network virus. In order to heighten defensive techniques of defensive tactics, this paper first build the ship network, and accordingly establish the SIS model for virus transmission. Then this paper puts forward the defensive tactics based on computer and network, hence raises the security of ship computer network system.
