Why?

Node.js applications often rely on third-party packages, which can introduce vulnerabilities.

How?

• Audit Dependencies Regularly:

Address issues identified in the audit report.

• Use Verified Libraries: Check the library’s documentation, versioning, and community activity before using it.
• Keep Dependencies Updated: Use tools like npm outdated to identify outdated packages.
• Avoid Over-Permissioned Dependencies: Limit the use of packages that request unnecessary system access.

2. Implement Proper Authentication and Authorization
