Attack Surface Reduction
Reducing your application's attack surface is the first layer of defense in your application’s security.
This involves minimizing the amount of code and features that could potentially expose your application to vulnerabilities.
In NextJS, one approach to achieve this is by utilising static generation, which pre-renders pages at build time.
This could minimize runtime errors, data exposure, or potential cross-site scripting (XSS) attacks as compared to traditional server-side rendering.
NextJS also supports incremental static regeneration, which enables developers to rebuild individual pages in the background as traffic comes in, allowing sensitive data to be updated safely and reducing the attack surface.
Safe Data Handling
Secure data handling is undoubtedly crucial in developing a secure NextJS application.
Vulnerabilities like SQL injection and XSS often stem from poor data handling practices.
NextJS API routes provide a good abstraction for communicating with your database directly or using an ORM like Prisma.
Using parameterized queries when dealing with user input can help you avoid SQL injection vulnerabilities.
Additionally, it's essential to sanitize user inputs and outputs to protect your application from XSS attacks.
Versatile Session Management
Session management in a NextJS application is best handled by JSON Web Tokens (JWT).
JWTs are secure, compact, and self-contained, making them ideal for session management.
Storing JWT in cookies (HTTPOnly and SameSite) enhances your application’s security.
HTTP Headers
Correctly configuring HTTP headers can enhance the security of your NextJS application.
Headers like Content-Security-Policy, HTTP Strict Transport Security (HSTS), and X-Frame-Options can help to prevent common vulnerabilities.
NextJS comes with built-in CSRF protection, and also allows you to easily configure these security headers.
