Abstract

Web safety is the developing direction of modern network technology in the 21st century. It is an applicative web based on JSP and mainly concerned with web safeguard studying. This web can help user communicate with each other online in terms of some questions about web safeguard. It mainly includes some main modules such as hot news, database and web safety, safeguard tools, password technology, invading test, safeguard discussion field, back platform management and so on. This web has been designed by using Macromedia Dreamweaver MX, PostgreSQL, Fireworks MX, Photoshop7.0 and JSP technology. Mainly key technology is combining PostgreSQL database to JSP. Among them, safeguard discussion field is designed in the form of chatting room online, and it is convenient for people to communicate with each other directly. This web has finished these functions such as search, file uploading, files downloading on screen which can help browsers to find the needed information as quickly as possible. Moreover, people can have the authority to release different kinds of commercial information on the website after registering. For example, system safeguard, invading test, safeguard technology information or other information release. This system has also set up the authority, divided into ordinary user and administrator. Only the administrator has the right to revise the database. The user's needs are stuck closely on this network. It is simple and easy to operate and it is beautiful for the whole output. It is the perfect embodiment of information-based management. This network, make the train of the enterprises more convenient, more high-efficient. At the beginning, this paper describes the necessity, background and importance of developing this network safeguard studying web. Later, it gives an introduction of the system requirement, key technology and some knowledge of developing skill. Then, it pays much attention to the system application analysis, function description, key skills, system database design, etc. In addition, the creation of the network is also attached much importance to here. At last, it points to the shortage of the system as well.
