A library WLAN team compares Protected Management Frames (PMF / 802.11w) set to optional versus required. What is PMF's main purpose?
Select an answer to reveal the explanation.
Short Explanation
Deauth spoofing is the fake 'fire drill' announcement that kicks everyone outside. PMF is the signed PA system — when it's required, random strangers can't as easily shout forged management commands over the air.
Full Explanation
Protected Management Frames (802.11w / PMF) cryptographically protect certain management frames so attackers cannot trivially forge them. Enforcing PMF (required) strengthens resistance to classes of deauthentication and similar spoofing compared with optional or disabled settings. PMF complements data confidentiality mechanisms; it does not revive WEP or replace captive-portal cosmetics.
