Question

Which of the following technologies is the MOST secure form of wireless encryption?

Options

ASSL
BWPA
CWEP
DTLS

Explanation

Among the listed options, WPA (Wi-Fi Protected Access) is the only technology specifically designed for wireless network encryption. WEP (Wired Equivalent Privacy) is an older, deprecated wireless encryption standard with well-known cryptographic weaknesses - it can be cracked in minutes. WPA replaced WEP with stronger encryption (TKIP and later AES via WPA2). SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are protocols that secure data in transit over networks (e.g., HTTPS), but they are not wireless encryption standards - they operate at the application/transport layer, not the Wi-Fi link layer. Therefore, WPA is the correct answer in this context.
