Access Control & RBAC
Implement secure access control systems with fine-grained permissions using RBAC, ABAC, or hybrid approaches.
Access Control Models
| Model | Description | Best For |
|---|---|---|
| RBAC | Role-based - users assigned to roles with permissions | Most applications |
| ABAC | Attribute-based - policies evaluate user/resource attributes | Complex rules |
| MAC | Mandatory - system-enforced classification levels | Government/military |
| DAC | Discretionary - resource owners control access | File systems |
| ReBAC | Relationship-based - access via entity relationships | Social apps |
