船载电子信息系统的计算机网络安全可靠性分析

The security analysis of computer networks in on-board electronic information system

得益于造船业和信息产业的不断发展,当前各种船舶的信息化水平和自动化水平不断提高,多种现代化电子信息系统在航运、传播控制等领域发挥着重要的作用,其中连接这些系统的通信网络,更是现代化船舶的神经中枢,对于船舶的运行和安全具有至关重要的意义。传统的计算机网络安全可靠性分析,往往仅仅针对网络的单一漏洞进行,而忽视了不同漏洞间的相关性。为解决这一问题,本文提出一种基于网络漏洞相关性的网络安全分析方法,其能够更好地适应船载网络安全环境,能够对船载网络进行更加全面和精准的安全性分析。

Thanks to the continuous development of shipbuilding industry and information industry,the current information and automation level of ships are increasing. Many kinds of modern electronic information system have be put into the field of shipping and transmission control,among which the communication network of the system is the nerve center of modern ships. Traditional computer network security reliability analysis,often only focus on a single network vulnerability,and ignore the correlation between different vulnerabilities. In order to solve this problem,this paper proposes a kind of network security based on network vulnerability correlation analysis method,which can better adapt the ship carrying network security environment,can give the ship loaded network security a more comprehensive and accurate analysis.
