The introduction of wireless networking provides many benefits, but it also creates new security threats and alters the organization’s overall information security risk profile. Although responding to wireless security threats and vulnerabilities often involves implementation of technological solutions, wireless security is primarily a management issue. Effective management of the threats associated with wireless technology requires a sound and thorough assessment of risk given the environment and development of a plan to mitigate identified threats. This chapter presents a framework to help managers understand and assess the various threats associated with the use of wireless technology. We also discuss a number of available measures for countering those threats.
