Years of designing, testing and deploying information architectures and technologies are paying off in the success of operation Enduring Freedom in Afghanistan. These successes in turn are laying the groundwork for future network-centric capabilities that will bring with them a considerable momentum for change in the U.S. defense infrastructure.

As successful as operation Enduring Freedom has been on the battlefields of Afghanistan, the lack of organizational reform in domestic U.S. agencies threatens the battle on the war's other front-the United States. Despite increased security measures and the heightened state of alert on the part of the public, the country is still highly vulnerable to further attacks by terrorists.

Networked terror groups, domestic radicals, renegade states and terror for profit all threaten Western democracies to an unprecedented degree. Prospective targets might be high-profile infrastructure assets with the potential for high casualty totals, or they might simply take the form of attacks on public institutions to rapidly erode confidence in governments.

The Internet protocol revolution is reaching satellite video communications with a new system that permits transmitting tens of thousands of channels over a single orbital transponder. Users can leapfrog existing satellite video limitations with two-way virtual private networks that can carry streaming video without a hitch.

After considerable interagency debate, the U.S. government has approved ultrawideband radio technology for commercial use. Ultrawideband devices operate across a wide spectrum range instead of a specific frequency. This allows for more efficient spectrum use at lower power levels and presents a possible solution for bandwidth-starved wireless providers. Other applications include ground-penetrating radar, imaging, surveillance and medical systems. However, issues such as possible interference with navigation and commercial aviation systems must be resolved before the technology gains wider acceptance.

As the world barrels headlong into the information age, a growing trend is beginning to alarm many experts in academia, industry and government. Despite the attractiveness of information technology (IT) as a profession, our prime stock of engineers and IT professionals has, by and large, been in our industry for more than 15 years.

The terrorist attacks of September 11 put the nation's critical information infrastructure to the test, and members of industry, the military and all levels of civil government came away from the experience with a new sense of urgency to work cooperatively to address the challenges revealed that day. According to security experts, existing emergency response infrastructures must be strengthened, critical information infrastructures must be protected and information exchange among federal, state and local law enforcement organizations must be expedited.

A recently developed software application will allow organizations to design layered access systems that scan individuals to recognize facial features, voices and lip movement characteristics. The program permits the deployment of a variety of digital-camera-based devices in kiosks and stations or desktop and laptop computers to control and monitor admittance to secure areas, networks or individual pieces of equipment.

International military partners are signing on and interfacing with each other instantaneously by using a prototype system that merges real-time chat capabilities with a language translator to enable cross-domain information exchange. The project addresses the need for collaboration and interoperation at the command level in allied environments.

The Federal Bureau of Investigation is turning to 21st century tools to solve today's crimes and move from a primarily reactive law enforcement approach to one that will allow agents to anticipate, then prevent, illegal acts. Data management capabilities will enable bureau personnel to identify relationships between cases as well as various sources of criminal activities.
