How to Secure Your Web Application from Common Vulnerabilities?

Securing a web application is critical for protecting sensitive data and maintaining user trust. Here are some common vulnerabilities and how to mitigate them:

• SQL Injection: Use parameterized queries or prepared statements to prevent SQL injection attacks. Never directly concatenate user input into SQL queries.
• Cross-Site Scripting (XSS): Sanitize user inputs and escape outputs to prevent XSS attacks. Use libraries like DOMPurify to clean HTML content.
• Cross-Site Request Forgery (CSRF): Implement anti-CSRF tokens in forms and use SameSite cookies to mitigate CSRF risks.
• Security Headers: Set HTTP security headers like Content Security Policy (CSP), X-Content-Type-Options, and X-Frame-Options to protect against various attacks.
• Regular Updates: Keep your software dependencies and frameworks up to date to patch known vulnerabilities.

By addressing these common vulnerabilities, you can significantly enhance the security of your web application.
