100-160 Question 88
Select 3A small office/home office (SoHo) user wants to set up a secure wireless network. Which of the following actions should they take to ensure their wireless network is as secure as possible?
- A
Enable WPA3 encryption for wireless security.
- B
Change the default SSID to something unique.
- C
Disable the router's firewall to improve performance.
- D
Use a strong, unique passphrase for the wireless network.
- E
Enable WEP encryption for backward compatibility with older devices.
Show answer and explanation
Correct answers: A, B, D
Explanation
To set up a secure wireless SoHo network, the user should enable WPA3 encryption for the highest level of security, change the default SSID to avoid broadcasting default router information, and use a strong, unique passphrase to prevent unauthorized access. Disabling the router's firewall and using outdated encryption like WEP are security risks and should be avoided.
- A. Correct.
WPA3 is the most secure encryption standard available for wireless networks, offering strong protection against modern attacks. This is a critical step in securing a SoHo network.
- B. Correct.
Changing the default SSID helps to hide information about the router's manufacturer and reduces the risk of targeted attacks exploiting known vulnerabilities.
- C. Incorrect.
Disabling the router's firewall reduces network security and exposes the network to potential threats. This is the opposite of what should be done.
- D. Correct.
Using a strong, unique passphrase ensures that unauthorized users cannot easily gain access to the wireless network, even with brute force or dictionary attacks.
- E. Incorrect.
WEP is an outdated encryption standard with well-known vulnerabilities. It should not be used, as it provides very little protection against modern threats.
