Protecting web apps from vulnerabilities like cross-site scripting (XSS) and SQL injection.

Protecting web apps from vulnerabilities like cross-site scripting (XSS) and SQL injection requires implementing robust security measures. To prevent XSS, developers should validate and sanitize user input, ensuring that any data rendered on the page is escaped. Utilizing Content Security Policy (CSP) can further mitigate risks. For SQL injection, prepared statements and parameterized queries should be employed to separate SQL code from user data, preventing malicious manipulation. Regular security audits, penetration testing, and staying updated on security best practices are essential for maintaining a secure web application.
