Roles and least privilege
Role-based access gives each person exactly the screens and actions their job requires — and nothing more. An operator records stock movements; a reviewer approves; finance reconciles; an administrator configures. Each sees an appropriate slice of the system, not the whole thing.
The principle behind this is least privilege: the fewer powers a person holds, the smaller the blast radius when something goes wrong, whether by mistake or malice. Handing everyone full control feels convenient until a wrong click or a compromised login can change anything. Least privilege is not about distrust; it is about limiting how far any single error can travel.
Key takeaways
- Roles grant only the access a job needs — operator, reviewer, finance, admin.
- Least privilege shrinks the impact of any mistake or breach.
- It is about limiting blast radius, not about distrust.
