新网络环境下的计算机网络安全思考

摘要

Along with the computer the rapid development of Internet technology,network information has become the important component of the social development.It relates to the government,economy,culture,military and other fields.As a result of the new network environment,computer network consisting of formal diversity,terminal distribution and network openness,connectivity and other characteristics,resulting in network information vulnerable from hackers,computer system vulnerable to malicious software,so the network information resources security has become an important topic.This paper describes the common computer network security threats,and then put forward several commonly used network security measures.%随着计算机互联网技术的飞速发展,网络信息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。由于新的网络环境下,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,所以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中的威胁,进而提出几种常用的网络安全防范措施。
