Security testing ensures that applications are free from vulnerabilities like SQL Injection, XSS, CSRF, and IDOR. SQL Injection occurs when unsanitized inputs allow attackers to manipulate database queries. This can be mitigated by using parameterized queries, preventing direct injection. XSS allows attackers to inject malicious scripts into web pages, and can be prevented by properly sanitizing or escaping user inputs. CSRF tricks users into executing unwanted actions; using CSRF tokens helps verify request authenticity. IDOR allows unauthorized access to data by manipulating object references, which can be avoided by implementing proper authorization checks. By integrating these security measures, you can safeguard your application from common attacks.
