Motivated by the autumn vulnerability KRACK for WPA2 WiFi protocol, used by billions of devices, the non-governmental organization that distributes WiFi technology and certifies WiFi products - the WiFi Alliance, has disclosed four main functions of the new authentication protocol - WPA 3.
The first feature is a brute force attack protection feature by adopting a security policy to block the authentication process after several unsuccessful login attempts. This is a major feature in many existing applications, and it is logical for the WPA 3 to have such a functionality, given the amount of brute force attacks that WPA2 is subjected to.
The second feature is the ability to use devices near Wi-Fi as configuration panels for other devices. A user will be able to use their phone or tablet to configure WiFi WPA3 options on another device that might not have a screen such as smart locks/gates or intelligent bulbs, and so on.
The third and fourth features are related to the encryption capabilities included in WiFi WPA3. The third feature is "custom data encryption," which encrypts the connection between each device and the router or access point, and the fourth is an enhanced cryptographic standard that was described by the WiFi Alliance as "a 192-bit security suit", aligned with the "National Security Algorithm (CNSA)" suit from the National Security Systems Committee, which will more reliably protect Wi-Fi networks through its higher security requirements.
А switch to WPA3 doesn't mean that other network and router security measures should be neglected. Many devices will be stuck with WPA2, which was considered very secure for a long time, until it wasn't. The Wi-Fi Alliance will continue to improve WPA2, which is not going away anytime soon.
