ISC2 Systems Security Certified Practitioner (SSCP) Practice Question

Your organization operates hundreds of network switches and routers in branch offices. Administrators authenticate to the devices using RADIUS, but the security team notes that only user passwords are protected in transit and that RADIUS cannot restrict which configuration commands each engineer may run. Which change to the access-control design would most effectively address both issues?

  • Replace the RADIUS infrastructure with TACACS+ servers integrated with the corporate directory.

  • Enable MS-CHAPv2 authentication within the existing RADIUS configuration to protect credentials end-to-end.

  • Deploy IEEE 802.1X port-based authentication on all switch management interfaces.

  • Route administrator SSH sessions through an IPsec VPN while continuing to use RADIUS for AAA.
