A security professional provides a five step plan that can help your development team avoid writing code that is vulnerable to SQL injection, or SQLi, attacks.
SQL injection takes place when database software can’ t tell the difference between arbitrary data from the user and genuine commands from the application. When an attacker injects commands into the data they send to a database, they can take database control away from the application owner. This can lead to data corruption, leaks of confidential data, or the bypass of essential logic (e.g., authentication, authorization checks) .
The good news is that SQL injection is preventable using a special feature that allows database software to separate application commands from user-supplied data. Or, by preventing untrusted user data from going directly to the database.
Let’s look out onto a variety of actionable ways to steer clear of SQL injection attacks.
