Which of the following is an older wireless network security protocol?

WEP, or Wired Equivalent Privacy, is recognized as an older wireless network security protocol. It was established in the 1990s as an early attempt to secure wireless networks by implementing encryption for data transmitted over radio waves. However, WEP has significant vulnerabilities that have been exposed over time, making it less secure and largely obsolete for modern networking needs.

In contrast to WEP, WPA2 (Wi-Fi Protected Access II) is a more recent and much stronger security protocol that enhances the encryption techniques used and addresses the weaknesses found in WEP. 802.1X is an authentication method used in conjunction with WPA/WPA2 to provide port-based network access control, rather than being a security protocol by itself. BSSID refers to the Basic Service Set Identifier, which identifies a specific access point within a wireless network, rather than acting as a security protocol.
