Authorization Security

Quick Navigation: Level 1: Quick Start (5 min) → Level 2: Implementation (30 min) → Level 3: Mastery (Extended)

Level 1: Quick Start (<800 tokens, 5 minutes)

Core Principles

1. Least Privilege: Grant minimum permissions required (NIST AC-6)
2. Separation of Duties: No single user controls entire critical process
3. Defense in Depth: Multiple authorization checks at different layers
4. Fail Secure: Default deny, explicit allow
5. Audit Everything: Log all authorization decisions (AU-2)
