Certified Ethical Hacker (CEH) Practice Question

During a post-assessment briefing, you report that an attacker repeatedly forced employees off the company's WPA2-Enterprise WLAN by transmitting spoofed deauthentication frames. Management asks for a preventive control that can be deployed without replacing existing access points or requiring users to change their workflow. Which measure most effectively thwarts this specific attack?

  • Disable SSID broadcast and implement MAC address filtering on every access point

  • Enable IEEE 802.11w Protected Management Frames (PMF) on the WLAN and require compatible clients

  • Lower each access point's transmit power to reduce signal leakage outside the building

  • Switch the network to WEP with shared-key authentication to obscure traffic contents
