Security in System Design
Security by Design: Integrating protection from the ground up.
Security is not a feature you add at the end. It must be an architectural concern addressed at every layer of the stack.
Key Principles
- Least Privilege: Components should operate with minimum necessary permissions.
- Defense in Depth: Multiple layers of security controls (Network, Identity, App, Data).
- Zero Trust: Never trust, always verify. Authenticate and authorize every request.
- Data Protection: Encryption at Rest (KMS) and in Transit (TLS).
