(PMF): Why It’s a Must for Secure WiFi!
Have you ever been suddenly disconnected from WiFi, even though the signal was strong?
It might not have been a glitch—it could have been an attack! 
The Problem: WiFi’s Hidden Weakness
By default, WiFi management frames (like Deauthentication and Disassociation) are unencrypted. This means an attacker can spoof these frames and force devices to disconnect from the network at will.
No password needed. No advanced hacking skills required. Just a simple trick, and boom—your connection drops!
This is how attackers:
Kick devices off WiFi using deauthentication attacks (common in public hotspots).
Launch Denial-of-Service (DoS) attacks by flooding networks with fake disassociation
requests.
Perform Evil Twin attacks—forcing users to reconnect to a fake rogue AP.
So how do we stop this?
The Solution: 802.11w Protected Management Frames (PMF)
PMF encrypts and authenticates management frames, preventing attackers from forging them. This makes WiFi significantly more resilient against deauth attacks.
PMF operates in three modes:
Disabled – No protection (legacy mode, risky 
).
Optional – PMF is used if both AP and client support it (good for mixed environments
).
Required – PMF is enforced for all connections (most secure 
).
Why You Should Care
Mandatory in WPA3: If you’re using WPA3 security, PMF is automatically enabled.
OWE (Opportunistic Wireless Encryption) relies on PMF: Making public WiFi safer.
Prevents common WiFi hacking tools (like Aireplay-ng & mdk3) from disconnecting
users.

I’ll be sharing sniffer logs 
showing the difference between unencrypted vs. PMFprotected management frames. You’ll see how:
Deauthentication frames look in legacy WiFi (without PMF).
How PMF secures management frames, making them unreadable to attackers.
Things to Watch Out For
Some older devices (IoT, VoIP phones, printers) may struggle with PMF in Required
mode.
A good balance? Use “Optional” mode if you have legacy clients, but if all your devices
support it—go for Required for full security!
