Which of the following security protocols uses a single, manually configured, static key for data encryption that is shared by the client and the WAP?

A.
L2TP

B.
WEP

C.
IPSec

D.
WPA

Explanation:
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. WEP uses a single, manually configured, static key for data encryption that is shared by the client and the WAP.

Answer C, A, and D are incorrect. These protocols do not fulfill all the conditions specified in the question. Fact What is IPSec? Hide Internet Protocol Security (IPSec) is a method of securing datA.It secures traffic by using encryption and digital signing. It enhances the security of data as if an IPSec packet is captured, its contents cannot be read. IPSec also provides sender verification that ensures the certainty of the datagram’s origin to the receiver. Fact What is L2TP? Hide Layer 2 Tunneling Protocol (L2TP) is a more secure version of Point-to-Point Tunneling Protocol (PPTP). It provides tunneling, address assignment, and authentication. L2TP allows transfer of Point-to-Point Protocol (PPP) traffic between different networks. L2TP combines with IPSec to provide both tunneling and security for Internet Protocol (IP), Internetwork Packet Exchange (IPX), and other protocol packets across IP networks. Fact What is WPA? Hide Wi-fi Protected Access (WPA) is an interoperable security standard for Wireless LAN (WLAN). For using WPA, encryption is required. WPA provides encryption by using Temporal Key Integrity Protocol (TKIP). TKIP uses a new encryption algorithm, which is stronger than WEP algorithm. 802.1x authentication is required in WPA.
