The original 802.11 standard has since been modified and speeds increased as it continued its prime directive to prevent Man-in-the-Middle attacks, which it has for some time. WPA2 took over the security platform when it was announced by the Wi-Fi alliance back in 2004 as WEP (Wired Equivalent Privacy) became obsolete and WPA (Wi-Fi Protected Access) revealed its insecurity and speed issues. As a refresher, WEP was better than no security at all but its downfall was that it used a static key (albeit 64-bit or 128-bit) to encrypt traffic to and from the access point. This process can and was eventually exploit
ed by common, everyday computers as their clock speeds increased.
In 2018, Wi-Fi alliance announced and released WPA3, a more secure protocol for wireless networks. In a press release, they discussed a suite of new security features and focused on "two of the features that will deliver robust protections even when users choose passwords that fall short of typical complexity recommendations, and will simplify the process of configuring security for devices that have limited or no display interface. Another feature will strengthen user privacy in open networks through individualized data encryption.
