The Central Intelligence Agency is reallocating vital resources to address the urgent and long-term needs of the war on terrorism. In addition to transferring substantial numbers of analysts and increasing overseas operational activities, the agency is establishing new links with nontraditional domestic customers.

Rapidly changing technology, along with the high demand for well-trained communicators to support current operations, is testing the limits of the U.S. Army's human resources and training facilities. To meet this challenge, the service is moving quickly to ensure that the people who keep communications up and running have the skills they need for the systems they will use.

The U.S. Army is deploying a transportable satellite broadcast management and uplink system that features greater bandwidth than traditional satellite systems, reduces transmission time and frees space on other tactical communications equipment.

U.S. civilian emergency management and law enforcement agencies are becoming increasingly capable of interoperating with the U.S. Defense Department. By enhancing communications and computer networking systems, organizations are readying themselves for flexible multiagency and multiservice joint operations in the event of a natural or man-made disaster.

A new type of defensive software protects computer networks by actively identifying reconnaissance probes and blocking subsequent attacks. The program operates in front of a firewall by marking all incoming scans and probes. The mark consists of false data about servers and other applications. Any attempts to penetrate the system using the distorted information is treated as an attack and automatically stopped.

In the past year there has been spirited public debate about the future of the intelligence community. While this debate largely is rooted in the attacks of September 11, 2001, many of the issues currently being addressed go far beyond the war on terrorism. One of the central issues includes key aspects of the intelligence community's functions in an infocentric democracy that is transforming its military into a network-centric fighting force.

The Central Intelligence Agency and the U.S. military are embarking on a path to combine their complementary assets in the war on terrorism. Both national security elements have been taking on each other's characteristics-the military is transforming its force along a common denominator of information, while the intelligence community increasingly is engaging in active, even paramilitary, operations in the field.

Greater urgencies in both conventional and asymmetrical warfare are accelerating the development and deployment of measurement and signature intelligence systems. This rapidly growing discipline is delving into more diverse sources of data, and experts are advancing ways of using it to help other intelligence sensor systems. Concurrently, laboratory researchers are seeking to develop a totally new family of sensor systems that can detect everyday energy emissions from artificial and organic sources.

The U.S. Army has a new tool in its arsenal that allows mobile troops to gather intelligence about the location and activities of adversaries by pinpointing the source of signal transmissions and intercepting communications. The system will replace legacy electronic warfare systems that were developed more than 30 years ago, and it has already been deployed in Afghanistan in support of operation Enduring Freedom.

Information technology is widely and often wildly heralded as the key to rearming the U.S. military for networked conflict, marshaling a host of disparate and dispersed bureaucracies to secure the homeland, and exporting American principles of liberty and justice. But, cloaked by hubris is the indisputable fact that the worth of information technology is established not by how much it costs, but how intelligently it is employed and how well it satisfies user needs.
