Select Protection and Control Efforts

In the last several years, federal agencies have increasingly adopted the use of wireless technologies. While wireless technologies provide many potential benefits, including greater flexibility for a mobile workforce and ease of installation and use, they also pose significant risks to information and systems. Wireless technologies use radio waves instead of direct physical connections to transmit data between networks and devices. As a result, without proper security precautions, these data can be more easily intercepted and altered than if being transmitted through physical connections. This book examines the select protection and control efforts being utilized to secure federal agency wireless networks, the FDIC; and the national nuclear administration.
