Security should never be an afterthought. With Next.js 14, we have more tools than ever to build robust, secure web applications from the ground up.

1. Leveraging Server Actions Safely

Server Actions provide a powerful way to handle data mutations, but they must be implemented with proper authorization and input validation to prevent common vulnerabilities.

2. Implementing Content Security Policy (CSP)

A strong CSP is one of the most effective defenses against Cross-Site Scripting (XSS). We'll explore how to configure CSP headers in Next.js middleware and layouts.

3. Robust Authentication Patterns

From Auth.js to custom JWT solutions, choosing the right authentication pattern and ensuring secure session management is critical for protecting user data.
