SQL Injection Attacks and How to prevent them
SQL Injection is a critical security attack that exploits vulnerabilities in web applications by injecting malicious SQL queries. This can compromise sensitive information, result in data loss, or affect the application's behavior. Common causes of SQL injection vulnerabilities include lack of data validation, complicated queries, and inefficient error handling. There are multiple types of SQL Injections, such as in-band, blind, out-of-band, and stored procedure injections. Preventive measures include using prepared statements, validating and sanitizing user inputs, limiting database permissions, and deploying Web Application Firewalls.
