网络环境中安全防御措施的研究

Safety Defends the Research of the Measure in the Network Environment

随着网络带宽增加和网络应用的日益丰富,网络受到频繁的攻击,这种攻击采用了结合病毒、蠕虫、后门等多种方式,本文详细分析了蠕虫病毒及木马、黑客对网络的侵入和威胁,提出了安全防御措施,并阐述了利用Windows2003提供的防火墙为网络构筑安全防线的方法,Internet连接防火墙可以有效地栏截对Windows2003服务器的非法入侵,防止非法远程主机对服务器的扫描,提高Windows2003服务器的安全性,如果在用Windows2003构造的虚拟路由器上启用此防火墙功能,能够对整个内部网络起到很好的保护作用.

The Increase along with the network bandwidth is applied to enrich increasingly with network, the the network is subjected to the multifarious attack, the this kind the of attack the adoption concludes the to match the various ways the of virus, worm , back door...etc., The this text the was detailed the to analyze the worm virus and wood horse, the black guests the to the the network of the irruptive and threat, the put forward the the safety the defense measure, the and elaborated the to make the use of the the fire the wall that the Windows2003 provide the as the the method that the the network the constructs the the safe defense line, the the Internet conjunction fire wall can availably the column cuts to the illegal entry of the server of Windows2003, prevent froming the illegal long range host scanning to the server, the safety of the exaltation Windows2003 server, if be in use this fire wall function in using the virtual router that Windows2003 structure, can rise the good protection function to the whole internal network.
