Final answer:
RBAC (Role Based Access Control) defines access based on the roles assigned to users within an organization or system.
Step-by-step explanation:
Role Based Access Control (RBAC) is a security model that defines access to resources based on the roles assigned to users. In RBAC, access is defined by the roles individuals hold within an organization or system. Each role has a set of permissions associated with it, specifying what actions the role is allowed to perform.
For example, in a system with RBAC, an employee may have the role of 'Manager' and another employee may have the role of 'Employee'. The 'Manager' role may be granted access to create, edit, and delete files, while the 'Employee' role may only have access to view files. RBAC allows for the efficient management of access rights, as permissions can be assigned to roles rather than to each individual user.
In RBAC, access to resources is determined by comparing the roles assigned to a user with the permissions associated with those roles. If a user's role has the necessary permissions to perform a certain action, they are granted access. If not, the access is denied.
