1、企业网络平安解决方案篇一：企业网络平安解决方案的设计摘 要计算机网络的开展和技术的提高给网络的平安带来了很大的冲击,Internet的平安成了新信息平安的热点。网络平安，是计算机信息系统平安的一个重要方面。如同翻开了的潘多拉魔盒，计算机系统的互联，在大大扩展信息资源的共享空间的同时，也将其本身暴露在更多恶意攻击之下。如何保证网络信息存储、处理的平安和信息传输平安的问题，就是我们所谓的计算机网络平安。信息平安是指防止信息财产被成心的或偶然的非法授权泄露、更改、破坏或使信息被非法系统辩识、控制；确保信息的保密性、完整性、可用性、可控性。信息平安包括操作系统平安、数据库平安、网络平安、病毒防护、访问
2、控制、加密和鉴别七个方面。设计一个平安网络系统，必须做到既能有效地防止对网络系统的各种各样的攻击，保证系统的平安，同时又要有较高的本钱效益，操作的简易性，以及对用户的透明性和界面的友好性。针对计算机网络系统存在的平安性和可靠性问题，本文从网络平安的提出及定义、网络系统平安风险分析，网络攻击的一般手段，企业局域网平安设计的原那么及其配置方案提出一些见解，并且进行了总结，就当前网络上普遍的平安威胁，提出了网络平安设计的重要理念和平安管理标准并针对常见网络故障进行分析及解决,以使企业中的用户在计算机网络方面增强平安防范意识，实现了企业局域网的网络平安。 关键词：网络平安； 路由器； 防火墙； 交换机
