航天计算机网络安全防护技术综述

Survey of Spaceflight Computer Network Security Technique

综合分析和评述国内外网络信息安全的发展现状及其发展趋势,着重对航天计算机网络信息安全可能存在的各种威胁和脆弱性进行总体分析,综述保障航天计算机网络信息安全现有的各类主要技术与途径,提出采取诸如物理安全、备份与恢复、防病毒、身份认证、信息加密、入侵检测和审计等技术手段,以建成一个成功的航天计算机网络安全防护体系.

The current situation and trend of network information security technique development in the world are reviewed and analyzed in the paper. This paper presents an overall analysis of a wide variety of threats and vulnerability to the secure and reliable operation of our spaceflight computer network and the computers attached to it. To build a successful spaceflight computer network seeurity infrastructure, we examine different security tools and approaches available for use, and suggest techniques such as physical security, backup and recovery, antivirus, authentication and secrecy, intrusion detection and audit as basic countermeasures.
