The Wi-Fi Alliance formally released the new standard in Wi-Fi security called WPA 3. There are two standard protocols used to protect WI-Fi networks, WEP and WPA. WEP was consider insecure for years and was recommended never to be used as it could easily be cracked. WPA was the preferred protocol to secure Wi-Fi networks and recently hackers found a way to crack WPA 2 encryption fairly quickly.
WPA 2 vulnerabilities
The Wi-Fi Alliance quickly worked on a new standard (WPA3) to counter what is called the KRACK attack that makes WPA2 vulnerable. The last WPA update was 13 years ago when WPA2 was announced. The KRACK attack allows a hacker to decrypt Wi-Fi data secured with WPA 2 without knowing or obtaining the password. This means changing the password will not protect you against this attack. Considering the world is largely run on Wi-Fi this is a serious concern that affects everyone using Wi-Fi.
What does WPA 3 offer?
WPA 3 is designed to prevent KRACK attacks and increased protection against brute-force attacks.
It increases security by preventing attackers from decrypting old traffic after obtaining the Wi-Fi password.
Increased security through individual data encryption. This encrypts traffic to and from the access point to your device.
Increased encryption security with WPA 3 Enterprise that allows 192-bit encryption.
Wi-Fi Protected Setup (WPS) is replaced with a Wi-Fi Easy Connect, a more secure Wi-Fi setup protocol for easy setup of devices. Easy Connect uses QR codes and your smartphone to set up new devices.
When is it available?
Devices supporting WPA3 won't be released till later this year, and it will be a long time until all devices support it. Many accessories are just finally getting WPA2 support.
