Which of the following is a commonly used encryption protocol for securing Wi-Fi networks? WEP HTTP FTP SSL

Analysis

1. Understanding Encryption Protocols: Encryption protocols are essential for securing data transmission over networks, including Wi-Fi networks. The listed options represent various protocols used in different contexts.

2. Evaluating the Options:

   • WEP (Wired Equivalent Privacy): This is one of the oldest security protocols for wireless networks but is considered weak and vulnerable to attacks.
   • HTTP (HyperText Transfer Protocol): This is used for transferring data over the web but does not include encryption by default.
   • FTP (File Transfer Protocol): Like HTTP, this protocol is used for transferring files and is not secure by itself.
   • SSL (Secure Sockets Layer): This protocol is used to secure data being transmitted over the internet but is primarily associated with web traffic rather than directly with Wi-Fi encryption.

3. Conclusion: Among the options, WEP is the only protocol designed for securing Wi-Fi networks; however, it is outdated and insecure compared to modern protocols like WPA (Wi-Fi Protected Access).

Final Answer

The commonly used encryption protocol for securing Wi-Fi networks is WEP (Wired Equivalent Privacy), although it is important to note that it is no longer considered secure and has been largely replaced by more robust protocols like WPA2 or WPA3.
