摘 要

隨著信息化技術(shù)的飛速發(fā)展，許多有遠(yuǎn)見(jiàn)的企業(yè)都認(rèn)識(shí)到依托先進(jìn)的IT技術(shù)構(gòu)建企業(yè)自身的業(yè)務(wù)和運(yùn)營(yíng)平臺(tái)將極大地提升企業(yè)的核心競(jìng)爭(zhēng)力，使企業(yè)在殘酷的競(jìng)爭(zhēng)環(huán)境中脫穎而出。經(jīng)營(yíng)管理對(duì)計(jì)算機(jī)應(yīng)用系統(tǒng)的依賴性增強(qiáng)，計(jì)算機(jī)應(yīng)用系統(tǒng)對(duì)網(wǎng)絡(luò)的依賴性增強(qiáng)。計(jì)算機(jī)網(wǎng)絡(luò)規(guī)模不斷擴(kuò)大，網(wǎng)絡(luò)結(jié)構(gòu)日益復(fù)雜。計(jì)算機(jī)網(wǎng)絡(luò)和計(jì)算機(jī)應(yīng)用系統(tǒng)的正常運(yùn)行對(duì)網(wǎng)絡(luò)安全提出了更高的要求。信息安全防范應(yīng)做整體的考慮，全面覆蓋信息系統(tǒng)的各層次，針對(duì)網(wǎng)絡(luò)、系統(tǒng)、應(yīng)用、數(shù)據(jù)做全面的防范。信息安全防范體系模型顯示安全防范是一個(gè)動(dòng)態(tài)的過(guò)程，事前、事中和事后的技術(shù)手段應(yīng)當(dāng)完備，安全管理應(yīng)貫穿安全防范活動(dòng)的始終。

Abstract

Along with the rapid development of information technology, many farsighted enterprises realized depends on the advanced technology enterprise itself IT business and operation platform will greatly increase the core competitiveness of the enterprise, the enterprise in brutal competition environment. Management of computer application system, enhance the dependence of computer application system is more dependent on the network. The computer network, the network structure scale unceasingly expands increasingly complex. The computer network and computer application, the normal operation of the system of network security, put forward higher request. Information security should be considered comprehensively, covering the whole level of information system, network, system, application, make a comprehensive prevention data. Information security system models show safety is a dynamic process, a series of technical means shall be complete, safety management through the security of activity.



Key words: network security, Defense system, the solution
