Wireless networks are subject to more security issues than standard wired networks. Which wireless security protocol can prevent unauthorized devices from connecting to the wireless network?

Explanation

WPA2 (Wi-Fi Protected Access 2) is the wireless security protocol specifically designed to authenticate devices and control access to wireless networks. It uses a pre-shared key (PSK) or enterprise authentication to verify that only authorized devices can join - directly addressing the question's requirement of preventing unauthorized connections.

Why the distractors are wrong:

• RSA is an asymmetric encryption algorithm used for key exchange and digital signatures, not wireless access control.
• AES is a symmetric encryption cipher (actually used within WPA2 for encrypting data), but it is not itself an access-control protocol.
• DES is an older, now-broken symmetric encryption standard with no role in wireless network authentication.

Memory tip: Think "WPA2 = WiFi Permission Authority" - it's the bouncer at the door of your wireless network. AES and DES are locks on the data inside, while RSA is a math tool for key exchange; none of them control who gets through the door.
