Backend Security Practices for Modern Application Platforms

How to harden APIs, protect sessions, validate inputs, manage secrets, and reduce common attack surfaces in backend systems.

Backend security requires consistent validation, secure session handling, protected secrets management, and strict authorization checks at every boundary.

Rate limiting, CORS policy, audit logging, and container hardening all contribute to a more defensible production environment.

Security should be integrated into architecture and deployment workflows rather than handled as a final review step.
