Which of the following is a security protocol for wireless networks?

• A. WEP
• B. Wireless Protected Access (WPA)
• C. Bluetooth
• D. Open

Answer: (B)

Wireless network security protocols are designed to protect data as it travels over the air and to control who can access the network. Among the options, the one that represents a formal security protocol for Wi‑Fi is WPA. It was developed to address the weaknesses of the older WEP approach by providing stronger encryption and better authentication, typically using per-packet key management and integrity checks. Open networks offer no encryption, so data can be read by anyone nearby, and Bluetooth is a different technology focused on short-range device connections rather than securing a Wi‑Fi network. While WEP is also a security protocol, it is outdated and considered insecure, making WPA the better fit for a wireless security protocol in the context of this question.
