CompTIA Network+ (N10-008) — Question 357

The lack of a formal process to grant network permissions to different profiles of employees and contractors is leading to an increasing number of security incidents. Non-uniform and overly permissive network accesses are being granted. Which of the following would be the MOST appropriate method to improve the security of the environment?

Answer options

• A. Change the default permissions to implicit deny.
• B. Configure uniform ACLs to employees and NAC for contractors.
• C. Deploy an RDP server to centralize the access to the network.
• D. Implement role-based access control.

Correct answer: D

Explanation

Implementing role-based access control (RBAC) helps ensure that users receive only the permissions necessary for their job functions, thereby reducing the risk of excessive access. Other options, while beneficial in certain contexts, do not address the core issue of systematically managing permissions based on roles, which is essential for improving security in this scenario.
