Certified Ethical Hacker (CEH v11) — Question 193

In an attempt to increase the security of your network, you implement a solution that will help keep your wireless network undiscoverable and accessible only to those that know it.
How do you accomplish this?

Answer options

• A. Delete the wireless network
• B. Lock all users
• C. Disable SSID broadcasting
• D. Remove all passwords

Correct answer: C

Explanation

Disabling SSID broadcasting makes the wireless network invisible to casual users, thereby increasing security. Deleting the wireless network would make it inaccessible, while locking all users would not address the discoverability issue. Removing all passwords would actually decrease security, allowing anyone to access the network.
