Network staff are locking down servers, switches, and routers that support utility billing. Which hardening focus is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
Hardening is turning off the doors you do not need and locking the ones you use to manage the box. Extra listening services and wide-open management from the Internet are invitations, not shortcuts.
Full Explanation
Hardening infrastructure devices includes disabling unnecessary services and protecting management interfaces so only authorized administrative paths remain. Enabling unused services and exposing management planes broadly increases attack surface. Removing logging undermines detection after hardening. For servers, switches, and routers supporting municipal billing, reducing unused services and securing management planes are standard operational security techniques.
