What is “SQL injection”?
SQL Injection is one of the common attacking techniques used by hackers to get the critical data.
Hackers check for any loop hole in the system through which they can pass SQL queries which by passed the security checks and returns the critical data. This is known as SQL injection. It can allow hackers to steal the critical data or even crash a system.
SQL injections are very critical and needs to be avoided. Periodic security testing can prevent these attacks. SQL database security needed to be defined correctly and input boxes and special characters should be handled properly.
