SQL Injection is one of the common attacking techniques used by hackers to get critical data.
Hackers check for any loophole in the system through which they can pass SQL queries, bypass the security checks, and return back the critical data. This is known as SQL injection. It can allow hackers to steal critical data or even crash a system.
SQL injections are very critical and need to be avoided. Periodic security testing can prevent this kind of attack. SQL database security needs to be defined correctly and input boxes and special characters should be handled properly.
