网络技术突飞猛进的发展,随之出现了许多网络安全事件,这不仅使得大型网络和主机受到了严重威胁,而且桌面系统的安全也出现了一定问题。建立桌面防御系统是保障桌面系统安全的有效手段。本文首先分析了桌面系统所面临的安全问题,然后从个人防火墙、入侵检测和文件保护三个子系统提出了桌面防御系统的总体设计;最后结合桌面系统的应用环境与安全要求,提出了应用于桌面系统的安全技术方案。 The rapid development of network technology, followed by many network security incidents, which not only makes large-scale networks and hosts have been seriously threatened, but also the desktop security has some problems. Establishing a desktop defense system is an effective way to ensure the security of the desktop system. This paper first analyzes the security problems faced by the desktop system, and then presents the overall design of the desktop defense system from the personal firewall, intrusion detection and file protection three subsystems; Finally, combined with the desktop application environment and security requirements, put forward the application of the desktop System security technology program.
