局域网监听软件的设计与开发论文作者姓名：申请学位专业：网络工程申请学位类别：工学学士指导教师姓名（职称）：论文提交日期：局域网监听软件的设计与开发摘要网络监听软件是提供给网络安全管理人员进行安全管理的工具，可以用来监视网络的状态、数据流动情况以及网络上传输的信息，以获取有用信息。作为黑客来说，通过网络监听可以获取其所需信息（比如密码等）；对黑客活动和其他网络犯罪进行侦察、取证时，可以使用网络监听技术来获取必要的信息。因此，在目前研究和使用网络监听技术及相关工具，对于防护网络安全、打击网络犯罪具有重要的现实意义。本局域网监听软件主要利用Winpcap和Jpcap等工具进行开发，使用Java语言在Eclipse3.2环境下进行开发。软件主要实现了对网络上的数据进行监听，并分析出每一协议层的传输数据和协议层上主要字段的数据，然后将其显示出来，同时进行动态更新；另外，添加了一些附加功能（指定对象监听、饼状图显示、界面选择等）。经过测试与分析，说明了该软件运行稳定、可靠，具有一定的实际应用价值。关键词：局域网；网络监听；协议层；数据传输；对象监听DesignandDevelopmentofLANMonitoringSoftwareAbstractNetwork-monitoringsoftwareisasecuremanagementtoolprovidingforthenetworksecurityadministrator.Itcanobtainusefulinformationwhichmonitorsthenetworkstatus,dataflowingandinformationofnetworktransmitting.Hackerscangetthenecessaryinformation(suchaspasswordandsoon)bymeansofnetwork-monitoring.Hackermaygaintheinformationwhichitsneeds(forinstancepasswordandsoon)throughthenetwork-monitoring;Carryingontakingthereconnaissanceandcollectingtheevidencesaboutthehackeractivityandothernetworkcrime,wemayusethenetworkmonitortechnologytogaintheessentialinformation.Therefore,studyingandusingnetwork-monitoringtechnologyandthecorrelatetoolinpresent,itisimportantandpracticalsignificanceforprotectingnetworksecurityandattackingnetworkcrime.Thislocalareanetwork-monitoringsoftwaremainlyisdevelopedbyusingofWinpcap,Jpcap,theJavalanguageandsoonintheEclipse3.2environment.Thissoftwaremainlyrealizesmonitoringthenetworkdata,analyzesthetransmissiondataandthemainfielddataoneachprotocollayer,andthendemonstratesit,carriesonthedynamicrenewal.Simultaneously,thissoftwareincreasessomeattachmentfunctions(suchasassigningobjectmonitor,demonstratingofcakeshape,thechoiceofsurfaceetc.).Aftertestingandtheanalyzing,whichshowsthatthissoftwareisstable,reliable,andhavingthecertainpracticalapplicationvalue.Keywords:LAN;NetworkMonitoring;ProtocolLayer;DataTransmission;ObjectMonitoring目录论文总页数：33页1引言...............................................................................................................................................11.1课题背景................................................................................................................................11.2本课题研究的意义................................................................................................................11.3本课题的研究方法................................................................................................................11.4本论文主要工作....................................................................................................................22需求分析.......................................................................................................................................22.1需求分析概述........................................................................................................................22.2本软件的需求分析.................................................................................................................32.2.1本软件实现的目标.........................................................................................................32.2.2本软件的运行环境要求.................................................................................................32.2.3本软件的功能要求.........................................................................................................42.2.4本软件功能的扩充.........................................................................................................43理论基础与相关工具介绍...........................................................................................................43.1网络监听原理介绍................................................................................................................43.2TCP/IP的层次结构................................................................................................................53.2.1OSI与TCP/IP体系结构的比较....................................................................................53.2.2TCP/IP四层协议的表示方法举例.................................................................................73.2.3使用TCP/IP进行通信的示意图...................................................................................73.3Winpcap简介..........................................................................................................................83.4Jpcap简介...............................................................................................................................94设计思路.....................................................................................................................................104.1设计框架图..........................................................................................................................104.2设计步骤..............................................................................................................................114.2.1整体规划.......................................................................................................................114.2.2程序运行流程...................................................................................
