Users can submit a database query code, according to the results returned by the program, get some data he wants to know, this is the so-called SQL Injection, that is, SQL injection.

SQL injection attack is one of the database security attacks, hackers can insert arbitrary malicious SQL code into the database query, so that the attacker can completely control the database server behind the Web application. Attackers can use SQL injection vulnerabilities to bypass application security measures; can bypass authentication and authorization of web pages or Web applications, and retrieve the contents of the entire SQL database; and can use SQL injection to add, modify, and delete records in the database.

SQL injection vulnerabilities can affect any website or Web application that uses SQL databases such as MySQL,Oracle,SQL Server or others. Criminals may use it to gain unauthorized access to users' sensitive data: customer information, personal data, trade secrets, intellectual property rights, etc. SQL injection attacks are one of the oldest, most popular, and most dangerous vulnerabilities in Web applications.

SQL injection attacks can be effectively protected by database security protection technology, which includes database missing scan, database encryption, database firewall, data desensitization and database security audit system.
