ABSTRACTABSTRACT：As ABSTRACT ABSTRACT：As the fast development of Internet，the worm explosion appears to be happening with increasing frequency．Studying on the solutions to the prevention on worms becomes an urgent task on hand．However,the traditional merhords of defending and prevention against virus do not apply to the worms，because of the difjf．ercnces between wornl and virus．It seems that the old methods don’t work against thevarying WOrmS which are getting more and more mature． In this paper,at first,comparing the differences between worm and virus．we come to conclude the general features of worm，and give a detailed analysis of its framework and structure．Then，we describe some typical worm’s codes，study on the interior principles of worms，to gain a better understanding of computer WOrmS，which provide a therotic basis for WOrm defence． With the regards to research into the ways of warning and containment agaiast WOrmS，in the beginning we introduce some common containment techniques．on me basis of these defensing methods，the paper introduces a new method to monitor and wain against worms．This method is base on statisticing computer’S all weight of “outer degrees”，it will abstract the local area network to a graph which is creating dynamic，then it will calculates each node’S“outer degrees’’of the graph to implement the warning of worms．This techniquic perform well to the worms which using scanning as their spreading means．It could not anly detect the known worms．but also the unknown． KEYWORDS：Worm；Virus；Computer Network Security；Warning；Prevetion； CLASSNo：TP393 学位论文版权使用授权书本学位论文作者完全了解北京交通大学有关保留、使用学位论文的规定。特 学位论文版权使用授权书 本学位论文作者完全了解北京交通大学有关保留、使用学位论文的规定。特 授权北京交通大学可以将学位论文的全部或部分内容编入有关数据库进行检索， 并采用影印、缩印或扫描等复制手段保存、汇编以供查阅和借阅。同意学校向国 家有关部门或机构送交论文的复印件和磁盘。 (必威体育官网网址的学位论文在解密后适用本授权说明) 学位论文作者签名：欲l幺吩 导师签名： 签字日期：加苗年／月彦同 签字同期：9-J年／月弦Ft 独创性声明本人声明所呈交的学位论文是本人在导师指导下进行的研究工作和取得的研 独创性声明 本人声明所呈交的学位论文是本人在导师指导下进行的研究工作和取得的研 究成果，除了文中特别加以标注和致谢之处外，论文中不包含其他人已经发表或 撰写过的研究成果，也不包含为获得北京交通大学或其他教育机构的学位或证书 而使用过的材料
