Building a Secure Employee Document Portal with Node.js and Express
A tutorial walks through designing a secure employee document portal using Node.js and Express, focusing on separating authentication from resource-level authorization, enforcing tenant isolation in multi-tenant systems, keeping sensitive files out of public directories, and using expiring signed download URLs. It covers safe file upload handling with generated storage keys instead of user-controlled filenames, minimizing stored sensitive data, separating audit logs from debug logs, adding browser security headers like CSP, keeping the interface accessible, and testing failure paths (blocked cross-tenant or cross-employee access) alongside successful downloads.
