How to ensure the security of Jinan website construction website

The security of website program is one of the important factors that system developers must consider, because it involves many security problems of website builders and website users. If not handled properly, it may bring serious problems to users and managers of the system. At the same time, the security solution for Web applications is not only a technical problem, but also involves management and other aspects.

Technical developers may have used one or both of them, but sometimes we do not pay special attention to them in the development process. We do not pay attention to the security of the website when dealing with every detail, which may result in some security vulnerabilities. It is hoped that through this article, developers can pay more attention to system security, especially testers can ensure that Jinan website construction System safety, improve product quality.

SQL injection prevention technology

Why must SQL injection be prevented? A considerable number of programmers do not judge the legitimacy of the user input data when writing code, which makes the application have security risks. The most easily overlooked problem for novices is the SQL injection vulnerability. Using NBSI2.0 to scan online websites, we can find that some websites have SQL injection vulnerabilities. Users can submit a database query code and obtain some data they want to know according to the results returned by the program.

How to prevent SQL injection?

For example, when submitting information such as URLs and forms, you can prevent the exposure of error information through a filter code that prevents SQL injection, or you can turn to a page that prompts errors when the system makes errors. At the same time, the server permission setting is a very important aspect. Since there are many server configurations involved, this article will not introduce them.

For text input, if you want to check it, you must check it according to the nature of the field itself. For example, if it is age, it must be limited to a number, and the size must be limited to a range, such as 18-120. For user names, a collection should be created. The e-commerce database $"9. #+.+4&; 7,9 contains allowed characters or prohibited characters. The special point here is about checking procedures. At present, the program checks the input data through the client script in the foreground, so that attackers can easily bypass the check program. It is suggested to adopt the method of combining front and back office to ensure efficiency and improve security.
