Which practice helps prevent unauthorized access to Wi-Fi networks?
- Using default password
- Disabling SSID broadcast
- WEP encryption
- Open network
Answer: Disabling SSID broadcast
Disabling SSID broadcast hides network name from public scans, adding obscurity layer. However, strong security requires WPA3 encryption, complex password, MAC filtering, and regular firmware updates. WEP is broken; default passwords are easily guessable; open networks offer no protection.
