# API Reference: Role Mining for RBAC Optimization
|
||
|
||
## Input Format (CSV)
|
||
```csv
|
||
user,entitlement,system
|
||
john.doe,read_files,FileServer
|
||
john.doe,write_files,FileServer
|
||
jane.smith,read_files,FileServer
|
||
```
|
||
|
||
## Role Mining Algorithms
|
||
|
||
### Bottom-Up Mining
|
||
Finds exact permission sets shared by >= N users.
|
||
- Input: user-permission matrix
|
||
- Output: candidate roles with exact permission sets
|
||
- Parameter: `min_users` (default: 2)
|
||
|
||
### Top-Down Mining (Jaccard Clustering)
|
||
Groups users by permission similarity.
|
||
```
|
||
Jaccard(A, B) = |A ∩ B| / |A ∪ B|
|
||
```
|
||
- Threshold >= 0.8: strict similarity
|
||
- Threshold >= 0.6: moderate clustering
|
||
|
||
## Optimization Metrics
|
||
| Metric | Description |
|
||
|--------|-------------|
|
||
| Total Assignments | Sum of all user-permission pairs |
|
||
| Candidate Roles | Discovered role count |
|
||
| Role Coverage | Users assigned to candidate roles |
|
||
| Avg Permissions/User | Assignment density |
|
||
| Outlier Count | Users with unique permissions |

## NIST RBAC Model Levels
|
||
| Level | Description |
|
||
|-------|-------------|
|
||
| Core RBAC | Users, roles, permissions, sessions |
|
||
| Hierarchical | Role inheritance |
|
||
| Constrained | Separation of duty (SoD) |
|
||
| Symmetric | Permission-role review |
