What is Role-Based Access Control (RBAC)?
Role-based access control (RBAC) is an access control mechanism that defines roles and privileges to determine whether a user should be granted access to a resource. Roles are defined based on characteristics such as the user's location, department, seniority, or duties. Permissions are assigned to access (what the user can see), operations (what the user can do), and sessions (how long the user can do it).
What are the three basic rules of RBAC?
Role assignment: A user can use privileges if he is assigned a role.
Role-based authorization: A user's role must be authorized, which ensures that users can only access roles for which they are authorized.
Privilege Authorization: A user can exercise certain privileges if he is entitled to them based on role assignment and authorization.
What are the benefits of RBAC?
Adherence to the “Principle of Least Privilege”: RBAC helps realize zero-trust security by granting users the minimum number of access permissions based on their roles. A role defines a set of permissions required by a user to perform business tasks related to their job function.
Reduce administrative effort: Use RBAC to quickly add and switch roles and implement them globally across operating systems, platforms, and applications. Also, reduce the potential for error when assigning user permissions. RBAC can also help you easily integrate third-party users into your network.
Segregation of Duties: Since roles are separated, in theory, no single user can be the cause of a significant breach because the hacker is limited to the resources that account has access to.
Improve compliance: RBAC helps organizations meet compliance regulations on data protection and privacy, as well as statutory requirements enforced by regional and local authorities. This is possible because IT departments and executives can manage data access permissions based on user roles.
What is the difference between RBAC and ABAC?
While RBAC bases permissions on a user's role, attribute-based access control (ABAC) relies on user-related attributes (eg, job title, seniority level, job duties), resource (eg, file/application type, sensitivity or source). ), or context (eg, where, how, and/or when a resource is accessed).
ABAC exponentially increases permission selection options by adding specific attributes and adds another level of control compared to RBAC. While infinitely more flexible than RBAC, this flexibility also adds complexity that can increase risk if not implemented and managed properly.
Do identity and access management (IAM) solutions support RBAC?
Yes, our IAM solutions offer RBAC to simplify access management and ensure data privacy. This capability not only improves compliance with regional regulations, but also brings much-needed operational efficiency by leveraging role access privileges versus individually setting and managing user permissions.

Flexible definition of roles
With role-based access control (RBAC), it is the role of the user that determines their privileges. Permissions can include access, read, write, share, and decide.
Roles can be assigned based on authority or level in the organization, responsibilities, and/or skill competencies. With a role hierarchy, one role type can contain the attributes of many other individual roles.
RBAC - ABAC
Attribute-based access control, or ABAC, exponentially increases your permission options by adding specific attributes, such as a user's location or time of day.
While infinitely more flexible than RBAC, this flexibility also adds complexity that can increase risk if not implemented and managed properly. One of our cybersecurity experts will be happy to discuss whether RBAC or ABAC is right for your needs.
