Your company is going to add wireless connectivity to the existing LAN. You have concerns about the security of the wireless access and wish to implement encryption. Which of the following would be the best choice for you to use?

A.
WAP

B.
DES

C.
WEP

D.
PKI

Explanation:
Wired Equivalent Privacy (WEP) is a standard encryption protocol used in wireless networks and supported by all wireless routers and network adapters.
What is WEP?
Wired Equivalent Privacy (WEP) is a security protocol for wireless local area networks (WLANs). It has two components, authentication and encryption. It provides security, which is equivalent to wired networks, for wireless networks. WEP encrypts data on a wireless network by using a fixed secret key. WEP incorporates a checksum in each frame to provide protection against the attacks that attempt to reveal the key stream. Answer option D is incorrect. PKI (public key infrastructure) is used to exchange keys in symmetric encryption algorithms. Answer option B is incorrect. DES (Data Encryption Standard) is a symmetric key encryption algorithm that uses a 56 byte key and is a block cipher. Answer option A is incorrect. WAP (Wireless Access Point) is an acronym for a wireless hub or router. There is a wireless encryption that is newer than WEP, called WPA (Wi-Fi Protected Access) but that is not the same thing as WAP.
