CompTIA Security+ Question I-25

The practice of marking open wireless access points is called which of the following?

A. War dialing
B. War chalking
C. War driving
D. Evil twin

Answer: B

Explanation:
War chalking is the act of making chalk marks on outdoor surfaces (walls, sidewalks, buildings, sign posts, trees) to indicate the existence of an open wireless network connection, usually offering an Internet connection so that others can benefit from the free wireless access. The open connections typically come from the access points of wireless networks located within buildings to serve enterprises. The chalk symbols indicate the type of access point that is available at that specific spot.
