CompTIA Security+ Question G-18

A company plans to expand by hiring new engineers who work in highly specialized areas. Each engineer will have very different job requirements and use unique tools and applications in their job. Which of the following is MOST appropriate to use?

A. Role-based privileges
B. Credential management
C. User assigned privileges
D. User access

Answer: A

In this question, we have engineers who require different tools and applications according to their specialized job function. We can therefore use the Role-Based Access Control model. Role-Based Access Control (RBAC) models approach the problem of access control based on established roles in an organization. RBAC models implement access by job function or by responsibility. Each employee has one or more roles that allow access to specific information. If a person moves from one role to another, the access for the previous role will no longer be available. Instead of thinking “Denise needs to be able to edit files,” RBAC uses the logic “Editors need to be able to edit files” and “Denise is a member of the Editors group.” This model is always good for use in an environment in which there is high employee turnover.
