Node.js has achieved its fame in developing scalable and powerful web applications. However, the security concerns are high while developing on Node.js because it's vulnerable to several issues. Here are the top 10 best practices in Node.js security that one must bookmark:

Keep Dependencies Updated: Frequently update Node.js and all its dependencies to mitigate known vulnerabilities.

Use Secure Dependencies: Verify that third-party modules or libraries do not have any open security vulnerabilities before integrating them into the application.

Implement CORS securely, to avoid granting unwanted access to malicious sites. 

Always validate and sanitize user/external input data, to prevent attacks like SQL injection and XSS. 

Apply robust authentication mechanisms, like OAuth and JWT, and proper authorization checks should be in place to secure access to sensitive endpoints.
