IS management recently replaced its existing wired local area network (LAN) with a wireless infrastructure to accommodate the increased use of mobile devices within the organization. This will increase the risk of which of the following attacks?

A.
Port scanning

B.
Back door

C.
Man-in-the-middle

D.
War driving

Explanation:
A war driving attack uses a wireless Ethernet card, set in promiscuous mode, and a powerful antenna to penetrate wireless systems from outside. Port scanning will often target the external firewall of the organization. A back door is an opening leftin software that enables an unknown entry into a system. Man-in-the-middle attacks intercept a message and either replace or modify it.
