| Summary: | 碩士 === 靜宜大學 === 資訊傳播工程學系 === 100 === With the increasing number of Internet users and web sites, and the evolution of web 2.0, more and more personal data and commercial information can be retrieved through the Internet. In order to obtain the business and political benefits, malicious attacks on web sites occur frequently today. Therefore, enabling data protection on web sites and web applications is more and more important. Current network intrusion detection system can be used for comprehensive protection on local area network. However, this system is too heavy. When we need this intrusion detection system achieves a moderate performance, it usually requires more system resources, and that results in high costs to build this system; although general web firewall needs only small construction cost, its protection capabilities are not good enough. Therefore, this study proposes a lightweight web application firewall, which will focus on protecting simple web server environment. The proposed system can reduce the construction costs and resource, and also improve the protection capabilities. This will not only achieve the goal of green technologies, but also can be generally applied to the web servers of small businesses or schools. Furthermore, the system also provides a convenient administrator tool for web site analysis and management.
