Another example is that of the multi-man rule, where an authorized person may a access protected zone only when another authorized person(say his supervisor) swipes along with the person.

Role-based access control (RBAC) is an approach to handling security and permissions in which roles and permissions are assigned within an organization's IT infrastructure.

Rule-based access control can also be a schedule-based system as you can have a detailed report that how rules are being followed and will observe the metrics. This is known as role explosion, and its unavoidable for a big company. Disadvantages of the rule-based system The disadvantages of the RB system are as follows: Lot of manual work: The RB system demands deep knowledge of the domain as well as a lot of manual work Time consuming: Generating rules for a complex system is quite challenging and time consuming Most smart access control systems encompass a wide range of security features, which provide the required design flexibility to work with different organizational setups. In a MAC system, an operating system provides individual users with access based on data confidentiality and levels of user clearance. Mandatory access control (MAC) is a network-based access control where settings, policy and passwords are established and stored in one secure network and limited to system administrators. Axiomatics, Oracle, IBM, etc. When you get up to 500-odd people, you need most of the "big organisation" procedures, so there's not so much difference when you scale up further. There are also several disadvantages of the RBAC model. Traditionally, Rule-based access control has been used in MAC systems as an enforcement mechanism for the complex rules of access that MAC systems provide. The biggest drawback of rule-based access control is the amount of hands-on administrative work that these computer systems require.
