The security team of Debry Inc. decided to upgrade Wi-Fi security to thwart attacks such as dictionary attacks and key recovery attacks. For this purpose, the security team started implementing…

WPA (Wi-Fi Protected Access) is an older standard that uses TKIP and PSK, which are known to be vulnerable to several attacks and do not utilize the modern SAE protocol.

WEP (Wired Equivalent Privacy) is an outdated and highly insecure Wi-Fi encryption standard that is easily compromised and predates modern security protocols like SAE.

WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security standard and is specifically designed to address vulnerabilities found in previous versions by incorporating the Simultaneous Authentication of Equals (SAE) protocol in its personal mode. SAE replaces the PSK method, providing enhanced protection against dictionary attacks and key recovery attacks through a more robust key establishment process.

WPA2 (Wi-Fi Protected Access 2) primarily uses AES-CCMP but still relies on PSK for personal mode, making it susceptible to dictionary attacks if the PSK is weak, and it does not incorporate the SAE protocol.
