Evaluation On The Security Of Web Applications And Study Of The Technology Of Read-Write On Client Side In Security

With the development of the computer application technology, the web system will fast become the dominant computing model. The network application development is restricted by many factors. The security of web applications is the most important one in these factors. We should resolve the safety problems of web applications.In this paper, the advantages and disadvantages of web applications and methods and techniques of hackers attacking web applications are introduced and analyzed. I found out that the safety precautions of web applications are different from those of networks. The security measures for the web application program should be carried on at the levels of program and code. Therefore, I study the methods and contents that we use to evaluate the safety of web applications. A evaluate model is constructed. The methods and principles of writing safety programs are introduced. I suggest that we should think like a hacker to write safety program. At last, I realized the read-write on client side in security in a utility system, using ActiveX technique.
