In the context of MAX Security for wireless LAN, which measure is suggested?

• A. Use MAC filtering
• B. Use WEP
• C. Disable SSID broadcast
• D. Add a VPN to Wireless LAN

Answer: (D)

Protecting data in transit over a wireless LAN relies on encryption beyond what the wireless protocol alone provides. A VPN creates an encrypted tunnel between the endpoint and the central network, so even if someone can access the wireless medium or bypass basic access controls, they cannot read or tamper with the traffic without the VPN keys. This strong layer of protection helps secure confidentiality and integrity for all data crossing the air, and it works well regardless of the underlying wireless setup or potential misconfigurations. By contrast, MAC filtering can be defeated by spoofing a legitimate MAC address, WEP has known weaknesses that can be exploited, and hiding the SSID offers only obscurity rather than real protection. Therefore, adding a VPN to the Wireless LAN delivers the most robust security measure among the options.
