What does Wired Equivalent Privacy (WEP) primarily aim to achieve?

Wired Equivalent Privacy (WEP) primarily aims to ensure confidentiality similar to that of wired networks. This protocol was designed to provide a basic level of security for wireless networks, attempting to make wireless data communications as secure as those over a wired connection. WEP achieves this by encrypting the data that is transmitted over the air, thus protecting it from eavesdroppers and unauthorized access.

While WEP does include some measures for user authentication, its primary focus is on encryption and confidentiality, which means that the data cannot be easily intercepted and understood by unauthorized users. The encryption ensures that even if the data is captured, it remains unreadable without the correct keys.

Though WEP was a step towards improving wireless security, it has since been found to have several vulnerabilities, leading to the development of more advanced security protocols such as WPA (Wi-Fi Protected Access) and WPA2. Nonetheless, the core aim of WEP remains centered on achieving confidentiality, making option B the correct choice.
