计算机网络安全问题的成因及硬件防范技术分析

The Computer Network Security Causes of Problems and Hardware Guard Against Technical Analysis

互联网是一个开放性的信息来源,网络系统时常会遭受计算机病毒与黑客的攻击,因此,存储于计算机内的信息和数据随时可能遭受破坏、盗取,或导致计算机系统无法正常运行。防火墙作为首选的网络内外连接屏障,可有效保护计算机网络安全。本文通过分析网络安全问题产生的原因及其影响因素,以及防火墙、入侵检测系统的功能与安全防范措施,对现行计算机网络安全的硬件防范体系进行介绍。

The Internet is an open source of information,the network system often suffer from a computer virus and hacker attacks,there fore,stored in the computer information in and data may suffer damage,steal at any time,or lead to the computer system can not run nor mally.Firewall as the preferred network internal and external connection barrier,which can effectively protect the computer network secu rity.This paper analyzes the causes of the problem of network security and its influencing factors and firewall,intrusion detection system function and safety measures,to the current computer network security hardware protection system was introduced.
