SQL injection attacks

SQL injection attacks

SQL injection attacks are one of the common means for hackers to attack databases. With the development of B/S application development, more and more programmers are writing applications using this mode. However, due to the varying levels and experience of programmers, a considerable number of programmers did not judge the legitimacy of user input data when writing code, posing a security risk to the application. You can submit a piece of database query code and obtain the desired data based on the results returned by the program. This is called SQL injection, that is, SQL injection.
