Despite access control systems increasing in security, there are still instances where they can be tampered with and broken into. Rule-Based Access Control can also be implemented on a file or system level, restricting data access to business hours only, for instance. 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).
