SQL injection Topics--Finishing posts

SQL injection is accessed from the normal WWW port, and the surface seems to be no different from the general Web page access, so the current firewall in the market does not alert SQL injection, if the administrator does not view the IIS log habits, may be invaded for a long time will not be detected.
With the development of B/s pattern application development, more and more programmers use this model to write applications. However, due to the lack of entry threshold in this industry, the level and experience of programmers is also uneven, a large part of the programmer in writing code, the user does not judge the legality of input data, so that the application has a security risk. The user can submit a database query code, according to the results returned by the program, to obtain some of the data he wants to know, this is called SQL injection, that is, SQL injection.
SQL injection is accessed from the normal WWW port, and the surface seems to be no different from the general Web page access, so the current firewall in the market does not alert SQL injection, if the administrator does not view the IIS log habits, may be invaded for a long time will not be detected.
