WiFi Gets Massive Security Boost
The new WPA3 security protocol makes it much harder for hackers to steal data from WiFi connections.

(CCM) — Internet users can start to enjoy beefed-up security when they connect over WiFi from today thanks to the introduction of a new encryption protocol called WPA3. The new protocol will start to replace the existing WPA2 protocol which was introduced over a decade ago.

WPA3 makes it much harder for hackers to get hold of a WiFi user's password by guessing it repeatedly — a technique known as "brute forcing." It also introduces "forward secrecy." This means that if a hacker records an encrypted WiFi transmission and then later guesses the password, they will be unable to decrypt the captured transmission (although they will be able to decrypt any future transmissions).

The Wi-Fi Alliance, a body which overseas the adoption of new protocols, is now certifying products that support WPA3, so WPA3-certified routers and devices such as laptops and smartphones will start going on sale soon. It is likely that WPA3-certified devices will become increasingly common over the coming twelve months. WPA3 may also be added to some existing devices through a firmware update.

WPA3 devices will be backward compatible, so that they will still be able to connect to WiFI networks which still use the older WPA2 protocol.
