浅析计算机网络的安全威胁及防范策略

Analysis of Computer Network Security Threats and Prevention Strategies

随着计算机互联网技术的飞速发展，信息网络已经成为社会发展的重要组成部分。它涉及到政府、经济、文化、军事等诸多领域。由于计算机网络组成形式多样性、终端分布广和网络的开放性、互联性等特征，致使网络信息容易受到来自黑客窃取、计算机系统容易受恶意软件攻击。因此，网络信息资源的安全与保密成为一个重要的话题。本文详细阐述常见的计算机网络安全威胁，并提出几种常用的网络安全防范措施。

With the rapid development of Interact technology,inf-ormation computer network has become an important part of social development.It involves government,economic,cultural and military fields.As the diversity of the composition of computer networks,terminals are widely distributed and open networks,connectivity and other features,resulting in the network of information vulnerable to hackers,computer systems vulnerable to malicious software,therefore,network security and confidentiality of information resources become an important topic.This paper describes the common computer network security threats,and propose several commonly used network security measures.
