Access control systems have a chief role to play in keeping the businesses secured by enabling the users to grant or restrict access to specified resources or locations. At present, four primary access control models are available, which include the mandatory access control of MAC, role-based access control or RBAC, discretionary access control or DAC and rule-based access control or RBAC.
Each model is specific in outlining different permission levels and the way they are assigned. For learning in detail about the four access control systems types for the businesses, and determining the best-suited ones to the needs of your company, read till the end.
1. Mandatory Access Control (MAC)
Mandatory Access Control is at large regarded as the most restrictive access control system model existing. It allows the owner to control as well as manage the access on the basis of the settings as laid out by the programmed parameters of the system. Now, these parameters can neither be bypassed nor altered. The end-user need not exert control over the privileges or permissions. They are able to access just the access points, which the system owners permit them to access. Due to its high restriction level, MAC is generally used for the organizations and facilities in need of maximum security, like government facilities.
2. Role-Based Access Control (RBAC)
Even termed as non-discretionary access control, the role-based access control provides access on the basis of the individual’s position in a firm. The predefined roles in these systems are associated with specific permissions, and they permit the administrator in assigning just the needed access amount necessary for the particular individuals for doing their jobs. Owing to its simplicity, this access control system is the most popular form used in businesses. Nevertheless, RBAC is even having a few drawbacks, for instance, it cannot grant one-time permissions when there is a necessity to the exceptions to the standard permission.
3. Discretionary Access Control (DAC)
Discretionary access control belongs to the least restrictive access control type category. Under this very system, the individuals are given complete control over the objects they are owning and the programs in association with these objects. Then, the individuals will be able to determine them who are having the access to their objects through programming security level settings for the other users.
4. Rule-Based Access Control
The rule-based access control systems either assign or denies access to the users on the basis of a set of dynamic rules as well as the limitations as the owner or the system administrator has defined. All these rules are likely to limit access on the basis of multiple unique situations, like the time of the day, the individual’s location and the device that is used. Rules and permissions customizing ability make RBAC an ideal access control form for the businesses in need of a dynamic security solution.
The access control system is beneficial to the companies as the building-wide system is excellent for protecting the employees, information, patrons, equipment and more assets. The access control systems are best in identifying an individual, authenticating them and then permitting them entrance to their destination.
