Building Secure Web Applications

Security is not optional. This comprehensive guide covers authentication, authorization, encryption, HTTPS, input validation, and security headers to keep your applications safe.

Authentication & Authorization

Implement robust authentication mechanisms and ensure proper authorization checks for all sensitive operations.

Data Encryption

Encrypt sensitive data both in transit (HTTPS) and at rest (database encryption).

Input Validation

Always validate and sanitize user input to prevent injection attacks and other vulnerabilities.

Security Headers

Implement security headers like CSP, X-Frame-Options, and others to protect against common attacks.
