Certification began in June 2018, and WPA3 support has been mandatory for devices which bear the "Wi-Fi CERTIFIED™" logo since July 2020. In January 2018, the Wi-Fi Alliance announced WPA3 as a replacement to WPA2. Enterprises often enforce security using a certificate-based system to authenticate the connecting device, following the standard 802.11X. WPA2 uses an encryption device that encrypts the network with a 256-bit key the longer key length improves security over WEP. The current standard is WPA2 some hardware cannot support WPA2 without firmware upgrade or replacement. WEP was superseded in 2003 by WPA, a quick alternative at the time to improve security over WEP. It is a notoriously weak security standard: the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools. WEP is an old IEEE 802.11 standard from 1997. The most common type is Wi-Fi security, which includes Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA). The term may also refer to the protection of the wireless network itself from adversaries seeking to damage the confidentiality, integrity, or availability of the network. Wireless security is the prevention of unauthorized access or damage to computers or data using wireless networks, which include Wi-Fi networks.
