Approved for public release; distribution is unlimited; The advent of Wireless Local Area Networking (WLAN) has seen a widespread adoption of its technology and functionality in many different areas. Many studies show more and more organizations are extending their networks to incorporate wireless devices and their applications. Permitting wireless devices to access private networks however, further complicates the tasks of protecting the network and its resources from unauthorized access. Now that they have become a significant element in today's networks, selecting and deploying adequate security measures have become the focus of many research efforts. Typically, network managers implement countermeasures to augment security. The goal of this thesis is to research approaches that compliment existing security measures with fine grain access control measures. The Extensible Markup Language (XML) is adopted to accommodate such granular access control as it provides the mechanisms for scaling security down to the document content level.; Captain, United States Marine Corps

Approved for public release; distribution is unlimited; The majority of literature written on the economic impact of border security has indicated that the increased security following 9/11 has had adverse effects on the flow of foreign imports. This study measures the direct cost the Homeland Security Advisory System (HSAS) had on U.S. Customs and Border Protection (CBP) overtime spending and the indirect cost on the U.S. economy by reducing the daily flow of imports. Three case studies were conducted at the United States' largest ports of entry. Each compared CBP overtime spending and the daily flow of imports during the seven periods the HSAS was elevated to ORANGE between 2002 and 2005. The study found that increased threat levels of the HSAS resulted in 50% more overtime spending by CBP. However, the HSAS had no impact on the daily flow of imports into the United States during the seven periods of elevated security between 2002 and 2005.; Outstanding Thesis; US Air Force (USAF) author.
