ai-shell role delete <name>                        # Delete role
ai-shell role assign <user> <role>                 # Assign role to user
ai-shell role unassign <user> <role>               # Unassign role from user

# Permission Management
ai-shell permission grant <role> <resource> [--actions read,write]
ai-shell permission revoke <role> <resource>
ai-shell permission list [user-or-role]            # List permissions
ai-shell permission check <user> <resource> <action>  # Check permission

3.2 Permission Model

Permission Format

<resource>.<action>[.own]

Examples:
- database.read          # Read any database
- database.write.own     # Write only owned databases
- api.*                  # All API operations
- *                      # Super admin (all permissions)

Role Hierarchy Example

Admin (root)
├── database.* (all database operations)
├── api.* (all API operations)
└── user.* (all user operations)

Editor (inherits from Viewer)
├── database.write (from direct)
├── database.delete (from direct)
└── database.read (inherited from Viewer)

Viewer
└── database.read (direct)

3.3 Context-Aware Permissions

# Check if user can edit their own data
rbac.has_permission(
    user_id='user_123',
    permission='data.edit',
    context={
        'user_id': 'user_123',
        'resource_owner': 'user_123'
    }
)  # Returns True

# Check if user can edit someone else's data
rbac.has_permission(
    user_id='user_123',
    permission='data.edit',
    context={
        'user_id': 'user_123',
        'resource_owner': 'user_456'
    }
)  # Returns False (unless has admin permission)

---

3. Backup Vault: Regular encrypted backups of .vault/ directory
4. Limit Access: Restrict vault file permissions (0o600)
5. Monitor Access: Review audit logs for vault operations

RBAC Configuration

1. Principle of Least Privilege: Grant minimum required permissions
2. Role Hierarchy: Use inheritance to simplify management
3. Regular Reviews: Audit user roles quarterly
4. Separation of Duties: Implement for critical operations
5. Context-Aware Permissions: Use .own suffix for user-owned resources

Audit Logging

1. Enable Tamper-Proof Mode: Use TamperProofLogger in production
2. Regular Verification: Run ai-shell audit verify daily
3. Retention Policy: Configure based on compliance requirements
4. Export Logs: Regular exports for compliance and analysis
5. Monitor Anomalies: Set up alerts for suspicious activities

11. Performance Considerations

11.1 Encryption Performance

Operation	Time (avg)	Throughput
Encrypt single credential	2-5ms	200-500 ops/sec
Decrypt single credential	2-5ms	200-500 ops/sec
Bulk import (100 creds)	200-500ms	200-500 creds/sec
Bulk export (100 creds)	150-300ms	333-667 creds/sec

11.2 RBAC Performance

Operation	Time (avg)	Complexity
Permission check	<1ms	O(1) - O(n)
Role hierarchy lookup	<2ms	O(depth)
Grant permission	<1ms	O(1)
List user permissions	<5ms	O(roles × perms)

11.3 Audit Performance

Operation	Time (avg)	Notes
Log action	1-3ms	Includes hash calculation
Search logs	10-50ms	Depends on log count
Verify integrity	50-200ms	For 1000 logs
Export logs	100-500ms	For 1000 logs

11.4 Optimization Tips

1. Batch Operations: Use bulk import/export for multiple credentials
2. Caching: Cache frequently accessed permissions
3. Async Operations: Use async for non-critical operations
4. Index Audit Logs: For faster searching
5. Lazy Loading: Load credentials on demand
