Interactive: Scenario Matcher

For each scenario, choose the best permission model and see if you are right:

Small Startup (20 employees)

Simple organizational structure with basic access needs

Requirements:
Clear role hierarchyEasy to understandQuick to implement

Healthcare System

Time-based access, patient context, emergency overrides

Requirements:
Context-awareTime restrictionsDynamic rules

Distributed File System

Users delegate access rights to others, peer-to-peer sharing

Requirements:
Delegation supportDecentralizedTransferable permissions

Simple Document Repository

Per-file access control, no complex rules needed

Requirements:
Resource-centricSimple permissionsPer-item control

Decision Framework

Start Simple

Begin with RBAC for basic access control. Most organizations can start here and expand later.

Add Complexity

Introduce ABAC when you need context-aware rules: time-based access, location restrictions, dynamic policies.

Enable Delegation

Use capability-based security when users need to delegate access to others without admin intervention.

Resource-Centric

Choose ACL for simple per-resource permissions where each item manages its own access list.

💡
Hybrid Approaches

Most production systems combine models: use RBAC for basic structure, ABAC for exceptions, and capabilities for delegation. Start simple, measure your needs, and add complexity only when required.
