-The attacker has set up an access point with the same network ID as the legitimate
access point.
Wireless DoS Attacks
Ans: - RF jamming techniqes/tools

Data at the wireless-to-wired interconnection points and carried over link along the
rest of the (typically wired) path is ____________ [by the wireless security
measures].
Ans: not protected

Ans: end-to-end protection
virtual private network (VPN)
Ans: using public network facilities and adding end-to-end security measures to make
the VPN like a network using "private" facilities.
encryption options to protect data transmitted on the 802 II Standard
Ans: Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), and WPA2
Wired Equivalent Privacy (WEP)
Ans: -An IEEE 802.11 security protocol designed in 1997 to ensure that only authorized
parties can view transmitted wireless information.
-uses the RC4 encryption cipher with a unique initialization vector for each frame sent
Initialization Vector (IV)
Ans: A 24-bit value used in WEP that changes each time a packet is encrypted.
How does WEP work?
Ans: each station using the access point uses the same (shared) key. The key is
supposed to be secret, so knowing it "authenticates"
