A secure use case needs more than a login. Ownership, permission, approved models and later review must fit together.
Permissions must match the specific use case.
Access to the platform does not by itself determine which data a person may see or which tools they may execute. These decisions are made for the relevant workspace and work context. Roles should therefore follow the actual task as closely as possible.
Ongoing operations also require changes and security-relevant activity to remain attributable to the correct context. Technical controls support this work, but they do not replace named ownership or the organization’s operating rules.
