Short for
Wired
Equivalent
Privacy, a security protocol for wireless
local area networks (
WLANs)
defined in the
802.11b standard. WEP is designed to provide the same level of
security as that of a wired
LAN. LANs are inherently more secure than
WLANs
because LANs are somewhat protected by the physicality's
of their structure, having some or all part of the network inside a
building that can be protected from unauthorized access. WLANs,
which are over radio waves, do not have the same physical structure
and therefore are more vulnerable to tampering. WEP aims to provide
security by
encrypting
data over radio waves so that it is protected as it is transmitted
from one end point to another. However, it has been found that WEP
is not as secure as once believed. WEP is used at the two lowest
layers of the
OSI model - the data link and physical layers; it therefore does
not offer end-to-end security
