With the ever increasing digitalization of our society, managing access to resources and enforcing authorization mechanisms becomes an ever more pressing issue. Thus, businesses worldwide need to familiarize themselves with the different access control models currently in vogue. These models are referred to as Role Based Access Control (RBAC), Attribute Based Access Control (ABAC) and Policy Based Access Control (PBAC).
RBAC is the oldest of the three models and it has the most traditional approach to permission management. It defines permission sets that are or can be assigned to particular users or user roles. This is done in the form of granting or denying access rights, like read, write or execute.
ABAC works very similarly, but with an added layer of complexity. It defines access layers in terms of various attributes such as user identity, job title and location. This allows for a more flexible approach to granting and denying access rights.
On the other hand, PBAC is an evolution of ABAC and is a more dynamic approach to access control. In addition to controlling access rights, it can also be used to generate rules and measure compliance.
Each of these authorization models has its advantages and disadvantages, and can be applied in different scenarios. For instance, RBAC is mostly used for static environments, such as a computer network, while ABAC and PBAC are better suited for more dynamic purposes, like applied to cloud computing.
For businesses in need of an effective access management system, they need to know and understand the differences between RBAC, ABAC and PBAC in order to determine which one is most suitable for their needs. They also need to consider factors such as the intensity of usage, scalability and type of data and resources represented and manipulated.
By understanding the principles of each of these authorization models, it’s possible to ensure a secure and effective enterprise security system and guarantee improved identity management, access rights enforcement and privilege levels monitoring. With the correct combination of RBAC, ABAC and PBAC, businesses can successfully manage user permissions, enforcement rules and access policies.
