Step 10: Security
Navigation: Main Index | ← Step 9: Observability | Step 11: Trade-offs →
Overview
This step covers authentication, authorization, encryption, and security best practices for system design.
Topics Covered
1. Tokens for Authentication
- JWT tokens
- Token-based authentication
- Refresh tokens
- Security considerations
2. SSO & OAuth
- Single Sign-On
- OAuth 2.0 flow
- OpenID Connect
- Implementation patterns
3. Access Control List & Rule Engines
- RBAC, ABAC
- Policy engines
- Fine-grained access control
- Implementation
4. Encryption & Its Types
- Symmetric vs asymmetric encryption
- TLS/SSL
- Encryption at rest vs in transit
- Key management
