Definition and purpose
WPA3 is a family of Wi-Fi security mechanisms designed to improve wireless connection protection compared with WPA2.
Technical operation
WPA3-Personal uses SAE instead of the traditional WPA2-PSK handshake, improving resistance to offline password-guessing attacks. WPA3-Enterprise addresses managed authentication requirements, typically through 802.1X and RADIUS.
Practical example
An organization may run WPA3-Enterprise for managed laptops while keeping a separate guest network for devices with different capabilities. Transition modes require compatibility and risk assessment.
Operational considerations
Update access points and clients, apply protected management frame requirements, test older devices and remember that WPA3 alone does not prevent every rogue access-point or phishing scenario.
