100-160 Question 90
Select 3You are tasked with setting up a secure wireless network for a small office/home office (SoHo). Which of the following actions will enhance the security of the network?
- A
Enable WPA3 encryption for the wireless network.
- B
Disable the SSID broadcast to hide the network from being visible.
- C
Use a default router admin username and password to simplify management.
- D
Enable MAC address filtering to restrict device access.
- E
Use a strong, unique passphrase for the wireless network.
Show answer and explanation
Correct answers: A, D, E
Explanation
To set up a secure wireless SoHo network, it is critical to enable modern encryption protocols like WPA3, use a strong and unique passphrase, and implement additional measures such as MAC address filtering to restrict access. Avoid relying on weak practices like hiding the SSID or using default credentials, as they do not provide significant security benefits.
- A. Correct.
Enabling WPA3 encryption provides the most secure wireless encryption standard currently available, which protects the network from unauthorized access.
- B. Incorrect.
Disabling the SSID broadcast may seem like a security measure, but it does not effectively secure the network. Attackers can still detect hidden networks with specialized tools.
- C. Incorrect.
Using a default router admin username and password is a poor security practice, as it leaves the network vulnerable to unauthorized access.
- D. Correct.
Enabling MAC address filtering adds an additional layer of security by allowing only specific devices to connect, although it is not foolproof against attackers who can spoof MAC addresses.
- E. Correct.
Using a strong, unique passphrase makes it significantly harder for attackers to guess the password and gain unauthorized access to the network.
