Information Security: Federal Agencies Need to Improve Controls over Wireless Networks;Report to the Congress

摘要

The use of wireless networks is becoming increasingly popular. Wireless networks extend the range of traditional wired networks by using radio waves to transmit data to wireless-enabled devices such as laptops. They can offer federal agencies many potential benefits but they are difficult to secure. GAO was asked to study the security of wireless networks operating within federal facilities. This report (1) describes the benefits and challenges associated with securing wireless networks, (2) identifies the controls available to assist federal agencies in securing wireless networks, (3) analyzes the wireless security controls reported by each of the 24 agencies under the Chief Financial Officers (CFO) Act of 1990, and (4) assesses the security of wireless networks at the headquarters of six federal agencies in Washington, D.C.
