Wi-Fi is getting way more secure, thanks to WPA3

Wi-Fi is getting way more secure, thanks to WPA3 Wireless local area networks (WLAN) are going to get much, much more safe in the near future. At the Consumer Electronics Show (CES) in Las Vegas, the new WPA3 standard for Wi-Fi was introduced.
WPA2 has been in use since 2004 and has been found to be less than optimal for the safety needs of modern Wi-Fi users. The largest differences between WPA2 and WPA3 are in open network security. Currently in an open Wi-Fi network the connections between devices are not protected in any way, and thus listening and manipulating traffic is very easy.

WPA3, however, introduces a specification for device specific encyption, which means that even if the network can be accessed without passwords you'll be able to securely transmit data without worrying about interception by other devices.

The new standard also includes a feature which allows network operator to deny access from a device to a network when the password has been guessed wrong multiple times. This protects against the so-called brute force attacks.

Wi-Fi Alliance expects the WPA3 standard to be released later this year.

Any word on if this will be something that relatively newer WiFi cards and routers can be upgraded to support? It would suck to have to get a new WiFi card and/or router to support this

Not only that but think about every single end user device that won't/can't be updated to support new encryption methods. I'm not sure if a software layer could 'future-proof' some devices (say, an Android phone) but everything you need to use on WPA/2 (hell, even WEP) will force you to open back up the vulnerability. The only solution would be to have a secure router for your PCs and other sensitive devices that support WPA3 that piggybacked onto an unsecure (WPA2-) router and only bridge the internet and not local networking.
