SQL Injection: What it is and How to Prevent it

Definition: SQL Injection is a type of cyber attack in which an attacker inserts malicious SQL code into input fields on a website to manipulate the underlying database.

Prevention: To prevent SQL injection attacks, IT security measures should include:

• Using parameterized queries in your code to bind user input data to predefined SQL query parameters.
• Implementing input validation to restrict the type and format of data that can be entered into input fields.
• Ensuring that user input is properly encoded before being processed by the database.
• Regularly updating and patching your database software to address any known vulnerabilities.

By following these preventive measures, you can significantly reduce the risk of SQL injection attacks and protect your sensitive data from exploitation.
