Implementing RBAC functionality in UNIX

Question

Hey please help me with this problem. I am new to UNIX systems and i want to ask is Role-Based access control possible in UNIX systems. Please see the details below:

Your manager wants to implement RBAC functionality. Your shop uses a UNIX system. You do not have a system with an implementation of RBAC available to you. You have the basic capabilities of UNIX/LINUX at your disposal for access control. You also have access control list functionality and sudo available. Discuss how far you can go implementing RBAC functionality with the tools at your disposal? What RBAC functionality would be difficult or not practical to implement?

Answer 1

You can have a look at Power Broker from BeyondTrust - that is if you can buy a solution (I don't work for them).

Also there has been quite some research on this topic at the university of Leuven. Here is their paper: www.cosic.esat.kuleuven.be/sesame/papers/wetice97.pdf

They would know how best to achieve RBAC in UNIX systems.
