What are some of the disadvantages of RBAC?
The main disadvantage of RBAC is what is most often called the ‘role explosion’: due to the increasing number of different (real world) roles (sometimes differences are only very minor) you need an increasing number of (RBAC) roles to properly encapsulate the permissions (a permission in RBAC is an action/operation on an object/entity).
When do you need to change role models in RBAC?
Creating, modifying, and removing roles is an ongoing effort to ensure the health of your RBAC solution. As the organization changes, new systems are added or removed, the role models have to be reviewed and updated to match. Organizations must plan for this ongoing effort and staff appropriately. 5.
