网络安全技术的探讨

网络安全是建立在密码学及网络安全协议基础之上的技术.密码学是网络安全的核心,利用密码技术对信息进行加密传输和存储,对数据完整性和用户身份进行鉴别和验证,比传统的简单存取控制和授权等技术更为可靠.在技术上讲,网络安全是由安全的操作系统、应用系统、以及防病毒、防火墙、入侵检测、网络监控、信息审计、通信加密、灾难恢复和安全扫描等安全组件构成的.一个单独的组件是无法确保信息网络安全的,基于网络连接的安全问题也日益突出.

A discussion on network security technology

Network security is the techrology built on cryptology and on network security agreement foundation technology. Cryptology, the network security core, transmits and saves information and distinguishes and confirms data integrity and the user status cryptically by using the passasord techrology, which is more reliable than the traditional technologies of simple access control and authorization, etc. Technically speaking, network security is composed of the safe operating system, the application system, and such safety comporents as the anti-virus, the firewall, the invasion examination, the network monitor and control, the information auditing, the correspondence encryption, the disaster restoration with security modules and the safety scanning, etc. As an independent module is unable to guarantee the information network security, problems based on network connection security have become increasingly conspicuous.
