Wi-Fi Security Recommendation Tool

The Wi-Fi Security Recommendation Tool assists network engineers, IT administrators, and remote workers in selecting, deploying, and hardening wireless networks against eavesdropping and unauthorized intrusion. It evaluates environmental context (corporate enterprise, retail guest Wi-Fi, small office, home network) to produce tailored configuration blueprints.

It identifies critical wireless vulnerabilities including using shared pre-shared keys (PSK) in enterprise settings, missing Protected Management Frames (PMF) allowing deauthentication attacks, legacy WPA-TKIP support, and unsegmented guest wireless networks.

Under WPA2-Personal, client authentication relies on the 4-Way Handshake using a Pre-Shared Key (PSK). Attackers exploit this design through offline dictionary attacks: by capturing the 4-way handshake using a passive Wi-Fi adapter (or actively sending deauthentication packets to force a reconnect), an attacker can take the captured handshake offline and use GPU clusters to test billions of dictionary passwords per second with zero risk of detection.

WPA3-Personal replaces the vulnerable 4-way handshake with Simultaneous Authentication of Equals (SAE, Dragonfly Key Exchange, RFC 7664). SAE uses a zero-knowledge proof where passwords cannot be tested offline. An attacker must interact with the live access point for every single password guess, effectively rendering offline brute-force attacks impossible. Furthermore, SAE provides Forward Secrecy: compromising the password in the future does not allow decrypting previously captured wireless traffic.
