SQL Injection
SQL injection is a type of cyber attack where an attacker inserts malicious code into a website's database query. When a user inputs data (like a username or password), the website processes that data to retrieve information. If the website's code isn't secure, an attacker can manipulate the input to execute harmful commands, potentially accessing or damaging sensitive data. It’s akin to tricking a system into revealing secrets or causing it to behave unexpectedly. Proper security measures, like validating user inputs, are essential to prevent these vulnerabilities and protect data integrity.

SQL Injection is a cyber attack technique where an attacker manipulates a website's database through input fields, like login forms. By inserting malicious SQL code into these fields, they can access, modify, or delete sensitive data without authorization. This happens because the website does not properly validate user input. SQL Injection can compromise personal information, lead to data breaches, and disrupt services. Protecting against it involves using secure coding practices, such as validating inputs and employing prepared statements, to ensure that user inputs cannot alter the intended database queries.
