An IT admin has what we call “superuser” access. If you think about it like a sentence, RBAC is the subject and verb. Roles act as the foundation for providing access. Achieving Dynamic Access by Using Attributes You either have access or you don’t.ĭynamic authorization – also known as attribute-based access controls (ABAC) – enhances RBAC by taking into account different “attributes.” Attributes are the adjectives of the access control world because they incorporate an additional description of either the user or resource.īy incorporating these attributes, organizations can control user access more precisely, and with the flexibility of dynamic authorizations, better balance business and security requirements. Since RBAC was intended for on-premises data repositories, it creates a very strict, static set of permissions. However, digital transformation changes the way people interact with data resources. RBAC provides a strong foundation for setting access controls. Enhancing RBAC by Using Dynamic Authorizations in SAP However, since a standard employee is at the “bottom” of the hierarchy, RBAC prevents her from accessing the sensitive information that the CEO can access.

Therefore, the CEO role has access that also encompasses the type of access provided to the Vice President’s, line of business managers, and standard employees. For example, a Chief Executive Officer (CEO) needs to have a lot of access to sensitive information. RBAC has since evolved to include “hierarchies.” Hierarchies assign different roles different levels of access. Transaction authorization: A user can only interact with a resource to which she is authorized through her role memberships while also limited on a “need to know basis.”.Role authorization: When combined with role assignment, administrators authorize a set of credentials that can gain access to and interact with a system.Role assignment: Only users with the right login can gain access to and interact with a system or application.Understanding SAP Access Control Using Rolesįunctionally, a role is a collection of permissions using sets, relations, and mapping that align access needs to resources based and limit access on a “need to know” basis. Both RBAC and ABAC are ways that organizations can control authentication and authorization, but they perform different functions across an enterprise IT stack. As your company’s digital footprint grows, you can enhance your security posture by complementing your existing SAP Role-Based Access Controls (RBAC) with dynamic, Attribute-Based Access Controls (ABAC) to strengthen authentication and authorization.
