Guide: Role-Based Access Control (RBAC)
What is Role-Based Access Control?
Role-Based Access Control (RBAC), also known as Non discretionary Access Control, refers to a system where permissions are associated with roles, and users are assigned to these roles. So, a user's access is determined based on the role he/she has within the organization.
Why is it Important?
RBAC is significant due to its efficiency in managing user permissions in large organizations. It reduces the risk of accidental or intentional misuse of systems by ensuring users see only information that is appropriate for their role.
How does RBAC work?
In RBAC, permissions are not assigned to individual users, but roles. When a new user is created, they are assigned a role. The role comes with a set of permissions that decide what functions the user can perform or what data the user can view or modify.
Exam Tips: Answering Questions on RBAC
When answering exam questions regarding RBAC, keep in mind that RBAC is based on the roles that users hold in the organization and is quite useful in larger organizations. Be sure to emphasize its practicality in managing permissions effectively and reducing risks associated with access control. Also, note that in RBAC, 'least privilege' principle is applied, granting only the necessary access to users required to perform their jobs.

Role-Based Access Control practice test
Role-Based Access Control (RBAC) is a security model that assigns permissions to users based on their defined roles within an organization. The roles typically represent the job functions or responsibilities a user holds, and the permissions are based on the principle of least privilege, whereby users are only granted the minimum necessary access to perform their duties. RBAC provides a centralized and scalable method for managing permissions, reducing administrative effort, and improving security by ensuring users only have access to what they need. Additionally, RBAC can be combined with other access control mechanisms such as Discretionary Access Control (DAC) and Mandatory Access Control (MAC) to create hybrid models tailored to security requirements.
