CompTIA Network+ (N10-008) — Question 255
A network administrator is adding a new switch to the network. Which of the following network hardening techniques would be BEST to use once the switch is in production?
Answer options
- A. Disable unneeded ports
- B. Disable SSH service
- C. Disable MAC filtering
- D. Disable port security
Correct answer: A
Explanation
Disabling unneeded ports is crucial because it reduces the attack surface of the switch, preventing unauthorized access and potential vulnerabilities. Disabling SSH service would limit secure remote management, while disabling MAC filtering and port security could expose the network to unauthorized devices and attacks.
