Subject description: Wi-Fi security is starting to get its biggest upgrade in over a decade
 

https://www.theverge.com/circuitbreaker/2018/6/26/17501594/wpa3-wifi-security-certification

Wi-Fi devices have been using the same security protocol for over a decade. But today, that’ll begin to change: the Wi-Fi Alliance, which oversees adoption of the Wi-Fi standard, is beginning to certify products that support WPA3, the successor to the WPA2 security protocol that’s been in use since 2004.

The new protocol provides a number of additional protections for devices connected over Wi-Fi. One big improvement makes it harder for hackers to crack your password by guessing it over and over again, and another limits what data hackers can see even once they’ve uncovered the passcode. Nothing will change as far as users see it; you’ll still just type in your password and connect to the network.


The first big new feature in WPA3 is protection against offline, password-guessing attacks. This is where an attacker captures data from your Wi-Fi stream, brings it back to a private computer, and guesses passwords over and over again until they find a match. With WPA3, attackers are only supposed to be able to make a single guess against that offline data before it becomes useless; they’ll instead have to interact with the live Wi-Fi device every time they want to make a guess. (And that’s harder since they need to be physically present, and devices can be set up to protect against repeat guesses.)

WPA3’s other major addition, as highlighted by the Alliance, is forward secrecy. This is a privacy feature that prevents older data from being compromised by a later attack. So if an attacker captures an encrypted Wi-Fi transmission, then cracks the password, they still won’t be able to read the older data — they’d only be able to see new information currently flowing over the network.
