The best candidates should be those who can demonstrate a thorough grasp of access control approaches, such as network segmentation, role-based access control (RBAC), and authentication protocols. An ideal response would mention implementing strong authentication methods to verify user identities, such as RADIUS or TACACS+. Furthermore, applicants must show they can use RBAC to give user roles and permissions per job duties. Implementing efficient network segmentation techniques, such as dividing departments or user groups into their VLANs or subnets, is also crucial. Routine audits and monitoring tools are essential to confirm the effectiveness of access restrictions and identify unauthorized access attempts.
