Security Concepts
This section provides educational content on the security concepts that underpin Rack Gateway. Whether you’re new to infrastructure security or looking to deepen your understanding, these guides explain the “why” behind the “how.”
Why Understanding Concepts Matters
Section titled “Why Understanding Concepts Matters”Security tools are only as effective as the understanding behind their use. Misconfigurations often stem from conceptual gaps—not technical limitations. These guides aim to:
- Build intuition about security trade-offs
- Explain industry standards like OAuth 2.0 and RBAC
- Connect theory to practice with Rack Gateway examples
- Support compliance by documenting security rationale
Core Concepts
Section titled “Core Concepts”Authentication vs AuthorizationThe foundational distinction every security system builds upon.
OAuth 2.0 ExplainedHow modern authentication works, from tokens to PKCE.
RBAC PrinciplesRole-based access control design patterns and best practices.
Zero Trust SecurityThe security model that assumes breach and verifies continuously.
Security Mechanisms
Section titled “Security Mechanisms”Multi-Factor AuthenticationWhy passwords aren't enough and how MFA protects accounts.
Audit LoggingBuilding tamper-evident records for compliance and forensics.
Infrastructure GatewaysThe gateway pattern for securing internal services.
Reading Order
Section titled “Reading Order”For those new to infrastructure security, we recommend this order:
- Authentication vs Authorization - Start with the fundamentals
- OAuth 2.0 Explained - Understand modern authentication
- Zero Trust Security - Learn the overarching security philosophy
- RBAC Principles - Dive into access control design
- MFA Security - Add defense in depth
- Audit Logging - Enable accountability and compliance

How These Concepts Apply to Rack Gateway
Section titled “How These Concepts Apply to Rack Gateway”| Concept | Rack Gateway Implementation |
|---|---|
| Authentication | Google OAuth with session tokens |
| Authorization | Role-based access control (RBAC) |
| Zero Trust | Every request authenticated and authorized |
| MFA | TOTP, WebAuthn, YubiKey support |
| Audit Logging | Immutable logs with S3 WORM anchoring |
| Gateway Pattern | Single entry point to Convox rack |
