- C
Use a strong, complex passphrase for the Wi-Fi network
- D
Enable guest network access without a password for convenience
- E
Update the firmware of the wireless router to the latest version
- F
Use WEP encryption for compatibility with older devices
Show answer and explanation
Correct answers: A, C, E
Explanation
To set up a secure wireless SoHo network, you must use modern encryption protocols like WPA3, ensure the router firmware is up to date, and apply a strong passphrase to the network. Avoid outdated protocols like WEP, insecure practices like open guest networks, or relying on ineffective measures such as hiding the SSID.
- A. Correct.
Enabling WPA3 encryption ensures the highest level of wireless security currently available, protecting against modern threats.
- B. Incorrect.
Hiding the SSID is not an effective security measure, as determined attackers can still find the network using advanced tools. It can also cause connectivity issues for authorized users.
- C. Correct.
Using a strong, complex passphrase prevents brute force or dictionary attacks, ensuring only authorized users can access the network.
- D. Incorrect.
Enabling guest network access without a password creates a serious security vulnerability, as it allows anyone within range to connect to the network.
- E. Correct.
Updating the firmware ensures that the router is protected against known vulnerabilities and exploits, which is a critical step in securing the network.
- F. Incorrect.
Using WEP encryption is outdated and highly insecure, as it is vulnerable to numerous attacks and should never be used.
