SQL injection is a type of security vulnerability that allows an attacker to inject malicious code into a database-driven application through user input. It occurs when an application fails to properly sanitize user input before executing SQL queries against a database. You can learn SQL through SQL training to enhance your skill.
For example, if a web application takes user input and directly uses it in an SQL query without any kind of validation or sanitization, an attacker could potentially submit malicious SQL code as part of the input, which would be executed by the database. This could result in the attacker being able to view, modify, or delete sensitive data from the database, or even take control of the entire system.
SQL injection attacks can be prevented by using prepared statements with parameterized queries, which separate the SQL code from the user input and ensure that it is properly sanitized before execution. Additionally, input validation and output encoding can also help prevent SQL injection attacks.
