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 left in software that enables an unknown entry into a system. Man-in-the-middle
attacks intercept a message and either replace or modify it.
