【摘要】 随着互联网的发展,网络环境下的信息资源将面临着黑客攻击、病毒感染等一系列的威胁,如何保证数据的保密性、完整性、可靠性和可用性是个急待解决的问题。目前,我国对于网络信息安全的问题非常重视,许多科研机构和企事业单位也在这一领域进行着卓有成效的研究。然而,直接针对图书馆界网站内容防护的研究却不多,虽然大多数图书馆都已经建立了网站,但对于其网站的内容防护却少有关注,或重视不够。 围绕图书馆网站内容安全防护系统的研究与实现这一主题,本文所做的工作主要体现在: 1.在综合与比较现有信息系统安全防护模型的基础上,充分考虑了图书馆网站内容防护的应用背景,提出了网站内容安全防护模型。该模型较普通的网站内容防护模型,既具有针对特定的用户群,充分考虑图书馆网站内容防护的个性特点,也具有良好的可扩展性; 2.在深入分析数字签名技术、多线程技术的基础上,给出了签名文件的统一格式,实现了对网页防护的监控,提高了系统的效率; 3.设计与实现了图书馆网站内容安全防护系统,该系统由定制检测网页模块,定时检测模块,实时检测模块,日志管理模块和数据备份模块五部分组成。经测试,该系统较好地解决了图书馆网站内容安全防护问题,有效地提高了系统的安全性。 本论文的研究成果已经在某省图书馆网站得到应用,为图书馆网站内容防护的研究提供了新的思路和方法,具有一定的实用价值。更多还原

【Abstract】 With the development of Internet, information resources in network are threatened by the attack of hackers and viruses. It is urgent to guarantee the confidentiality, integrity, reliability and availability of information. Now, our country is beginning to realize the importance of the security of website information, and many scientific institutions and enterprises are researching and exploring in this field. However, there are only a few of researches straight aimed at content protected of library website. Many libraries have established their own websites, but few attention are paid to the content protection of website, or the recognition was not enough at all.Surrounding the research and implementation on Content Protection System of Library Website(CPSLW), the following contents are studied in this thesis.1.On the Base of the integration and comparison of the security protecting models of information system at present, a model of security protecting of Website content was proposed. Compared with common model of content protection of Website, this model has not only the characteristic of aiming at the specific user group, but also possesses good expansibility.2. Based on the thorough analysis of digital sign technique and multithreading technique, the uniform format of signature format was presented, the supervision of content protected of website was realized, and the efficiency of system was improved.3. The CPSLW is designed and realized. The system is composed of customizing checking web page module, timing checking module, real time checking module, log managing module, data backup module and so on. After tested, the problem of content security protection of library website was mainly solved, and the security of system was also improved effectively.The research done in this dissertation has already been applied to a library website of certain province. It provides a new method of library web content protection and has important practical values.更多还原
