The security of Web servers can be enhanced and the damage of illegal access can be avoided. Firstly, the system for discovering the patterns of information leakages in CGI scripts from Web log data was proposed. Secondly, those patterns for system administrators to modify their codes and enhance their Web site security were provided. The following aspects were described: one is to combine web application log with web log to extract more information,so web data mining could be used to mine web log for discovering the information that firewall and Information Detection System cannot find. Another approach is to propose an operation module of web site to enhance Web site security. In cluster server session, Density -Based Clustering technique is used to reduce resource cost and obtain better efficiency.展开更多

SQL injection is one of the most common types of web hacking and has been widely written and used in the wild. This paper analyzes the principle of SQL injection attacks on Web sites, presents methods available to prevent IIS + ASP + MSSQL web applications from these kinds of attacks, including secure coding within the web application, proper database configuration, deployment of IIS. The result is verified by WVS report.展开更多
