### 2025-05-03 13:15:00 - Role Inheritance Implementation Update
|
|
|
|
**Changes Made:**
|
|
- Updated `assign_role` method in RBACEngine to include circular inheritance validation
|
|
- Added call to `validate_circular_inheritance` when assigning roles with parents
|
|
- Maintained existing boundary validation and return signature
|
|
- Enhanced audit logging for inheritance validation failures
|
|
|
|
**Rationale:**
|
|
- Security requirements specify preventing circular inheritance chains
|
|
- Existing implementation only checked boundary restrictions
|
|
- New validation ensures role inheritance graphs remain acyclic
|
|
|
|
**Verification:**
|
|
- Changes successfully applied to rbac_engine.py
|
|
- Method maintains backward compatibility
|
|
- All existing tests should continue passing
|
|
- New tests for circular inheritance cases will be added in next step
|
|
|
|
**Next Steps:**
|
|
1. Add unit tests for circular inheritance scenarios
|
|
2. Verify boundary restrictions are still enforced
|
|
3. Update documentation to reflect new validation
|
|
### 2025-05-03 13:15:30 - Added RBAC Inheritance Test Cases
|
|
|
|
Added comprehensive test coverage for RBAC inheritance scenarios:
|
|
- Boundary restrictions with inheritance (test_boundary_restrictions_with_inheritance)
|
|
- Parent role working alongside role_inheritance (test_parent_role_with_inheritance)
|
|
- Multiple inheritance chains with boundaries (test_multiple_inheritance_chains)
|
|
|
|
All tests follow existing patterns and verify:
|
|
1. Inheritance of permissions works correctly
|
|
2. Boundary restrictions are enforced
|
|
3. Both parent_role and role_inheritance work together
|
|
4. Complex inheritance chains respect all restrictions
|
|
|
|
Next Steps:
|
|
- Verify test coverage meets requirements
|
|
- Run tests to confirm implementation |
