The Wi-Fi Alliance has introduced the first major security improvement to Wi-Fi in about 14 years: WPA3. The most significant additions to the new security protocol are greater protection for simple passwords, individualized encryption for personal and open networks, and even more secure encryption for enterprise networks.
The original Wi-Fi Protected Access (WPA) standard was released back in 2003 to replace WEP, and the second edition of WPA came the year after.
