Wi-Fi Alliance announces WPA3 to secure modern networks


The Consumer Electronics Show (CES) is an odd place to announce an enterprise product, but the Wi-Fi Alliance used the massive trade show — which has more or less taken over where Comdex left off — to announce a major upgrade to Wi-Fi security.

The alliance announced the Wi-Fi Protected Access 3 (WPA3), a new standard of Wi-Fi security that greatly increases the security capabilities of the wireless standard. WPA2, which is the current standard in wireless security, has been around for 14 years, so this is way overdue.

The update can’t come to market fast enough. Last fall, a major vulnerability in WPA2 and WPA called KRACK — for Key Reinstallation Attack — came to light. KRACK could allow attackers to snoop on encrypted data being transferred between computers and wireless access points.

4 enhancements in WPA3

There are four main enhancements to the standard, but the Alliance did not divulge technical details on how these will be implemented. The first is “robust protections” for people who use weak passwords, as well as protection against what are known as dictionary attacks to try and brute force the password.
