SQL Injection

SQL Injection is a cybersecurity vulnerability that occurs in database-driven websites when an attacker exploits poorly secured application code to insert or "inject" unauthorized SQL commands. This form of attack manipulates the underlying SQL database, which manages the dynamic content of the websites or applications, to perform operations that the attacker should not have the authority to execute.

The SQL Injection method is typically executed through user input areas of a web application, such as form fields, URL query strings, or cookies, where SQL commands can be inserted into strings that will be executed by the database server. This can result in a variety of harmful outcomes, including:

Preventing SQL Injection requires secure coding practices, including the use of prepared statements with parameterized queries, input validation, and escaping special characters. Regular security testing and updating of the applications to patch vulnerabilities are also critical steps in defending against SQL Injection attacks.

This form of attack underscores the importance of adhering to best practices in software development and database management to protect web applications from unauthorized access and compromise.
