CompTIA Security+ (SY0-601) — Question 762

A smart switch has the ability to monitor electrical levels and shut off power to a building in the event of power surge or other fault situation. The switch was installed on a wired network in a hospital and is monitored by the facilities department via a cloud application. The security administrator isolated the switch on a separate VLAN and set up a patching routine. Which of the following steps should also be taken to harden the smart switch?

Answer options

• A. Set up an air gap for the switch.
• B. Change the default password for the switch
• C. Place the switch in a Faraday cage.
• D. Install a cable lock on the switch.

Correct answer: B

Explanation

Changing the default password for the switch is essential to prevent unauthorized access, making it the best option for hardening security. The other options, while they may provide some level of security, do not directly address the critical issue of access control that a default password presents.
