You work as the security administrator at Certkiller .com. You want to prevent intruders from using
access points on your wireless network? Which solution should you implement?

A.
ESP (Encapsulating Security Payload)

B.
WEP (Wired Equivalent Privacy)

C.
TLS (Transport Layer Security)

D.
SSL (Secure Sockets Layer)

Explanation:
The 802.11 standard describes the communication that occurs in wireless local area networks
(LANs). The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless communication
from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless
network; this function is not an explicit goal in the 802.11 standard, but it is frequently considered
to be a feature of WEP.
Incorrect answers:
A: ESP is a header used to provide a mix of security services in IPv4 and IPv6. ESP can be used
alone or in combination with the IP Authentication Header (AH).
C: Transport Layer Security (TLS) is a protocol whose purpose is to verify that secure
communications between a server and a client remain secure. Not exactly prevention of intruders.

D: SSL is a protocol that secures messages by operating between the Application layer (HTTP)
and the Transport layer. It does not prevent intruders from intruding.
