【摘要】 科学技术的不断进步,使得信息技术得到了空前的发展,计算机和信息网络已经影响到人们生活、工作、学习和娱乐的方方面面。互联网(Internet)作为世界上最大的信息网络,从它诞生之日起,针对它和利用它的违法犯罪活动就如影随形,而且日趋猖獗,危害性也越来越大。作为公安机关网络安全保卫部门,就是要利用信息网络技术,提高预防和打击针对互联网及其他信息网络的违法犯罪活动的能力,降低此类违法犯罪案件的发案率,减少此类违法犯罪活动对公民个人、国家安全和整个社会稳定的危害,这是我们目前急需解决的问题。而减少针对包括互联网在内的信息网络的违法犯罪活动,不能仅仅是被动地提高网络安全技术水平,提高网络本身的安全防范能力,更重要的是要从法律层面给违法犯罪者以震慑,提高主动侦破和打击此类犯罪行为的能力。长春市的互联网安全状况也随着整个网络的不断发展,面临着日益严峻的考验。本文通过分析互联网犯罪形成的背景、发展、现状及过程,探讨互联网犯罪取证的相关理论及技术,设计并实现一个针对互联网攻击及入侵案件的取证系统方案,讨论并解决如何通过对在数据链路层上传输的以太帧进行分析,获取到IP地址、网络适配器MAC地址、网络协议和通讯内容等数据信息,以便对各种违法犯罪行为进行追踪、定位和取证,并能够校验所获取的信息是否被篡改以及监测整个系统的运行状态。但是,公安机关要真正通过互联网犯罪取证技术打击违法犯罪、震慑违法犯罪人员,就必须有强有力的法律后盾作支持。本文也将在随后分析指出互联网犯罪取证所涉及的法律问题和困难,通过对互联网安全立法的现状、发展前景的分析和研究,指出我国在互联网的立法和司法实践方面存在的问题,并提出如何完善互联网管理体系的个人观点。

【Abstract】 Computers and information networks play an indispensable role in ourlives, work,education and joy, with the incessant development of scientifictechnology and widely application of information technology. Internet(Internet), as the world’s largest computer network, has been used in criminalactivities which are rampant with the increasing risk, since it was born.Then, as the network security department of the public security, how in effectto prevent and fight against the criminal activities used in the Internetand other computer networks, and how to minimize the occurrence and the harmof such criminal activities has become the problems to be solved. For reducingcriminal activities used in computer networks, the network securitydepartment of the public security not only passively increases technologicallevel of the network security and the capability of the security of the networkitself, but also has to be from the legal aspects of criminal offenders todeter, and improves active detection and combating such the ability of thecriminal activities.With the development of the network, the internet security situation inChangchun is facing increasingly severe challenge. This paper analyzes theInternet Crime formation background, development, current status, andprocess, to research the Internet forensics theory and technology, to designand implement the forensics system scheme about the cases of Internet attackand intrusion, to discuss and solve the key technology issues in designprocess: according to the analysis of Ethernet frame in the link layer tocomplete access to tracking, the forensics necessary IP address, MAC address,and communication protocols, communications and content from the networktransmission underlying detailed information, check the core file has notbeen tampered as well as to monitor the important process of running state.However, the public securities deter the criminal and crack down on crimethrough the Internet forensics techniques, which must resort to legislationsupport. This article also points out in the subsequent analysis of the legalissues and difficulties involved in Internet forensics. Through the analysisand study of the current situation and development prospects of Internet security legislation, the author points out the problems on legislative andjudicial practices in China, and make recommendations accordingly to improveInternet management system.
