During the past 18 months, the topic of security has been explored in the pages of SIGNAL Magazine in dozens of articles and in at least a half dozen commentaries. Security also has been a priority for AFCEANs worldwide whose responsibilities range from ensuring network security to offering professional training, to enforcing disciplines and compliance and investing in technology. We know that we must set the bar very high and demonstrate that intrusions or disruptions of our networks is not an option. As information technology professionals, we recognize that security is a social, legal, technical and cultural issue and are working hard to cover all the bases.

Participants in this year's Joint Warrior Interoperability Demonstration (JWID) operated from sites around the world, and personnel at each site form their own impressions of the event's results. In addition to taking part in the multinational activity, the teams at the Naval Surface Warfare Center (NSWC), Dahlgren, Virginia, demonstrated some of their own programs that support military and homeland security efforts.

The increasing complexity of global geopolitics is weighing heavily on U.S. military planners as they gird for the next round of network-centric warfare. Both technological and cultural dynamics loom large in potential scenarios and outcomes.

The French military is enhancing its global communications capabilities with a new generation of dedicated satellites designed to simultaneously link several theaters of operation. The spacecraft features multiple antennas operating on different radio frequencies that can be aimed to provide highly focused, secure links to mobile and fixed groundstations.

An advanced Swedish radar system capable of rapidly detecting and tracking multiple targets provides commanders with precious additional seconds in medium- and short-range air defense engagements. The radar can quickly sweep a section of sky in three dimensions and relay data to weapons platforms or to other sensors on a network.

Front line British troops soon will be able to access maintenance documentation electronically through a portal-based software system. By clicking on an icon, personnel will download data onto their laptops or handheld computers for immediate reference at flight lines or repair operations. The technology saves space in logistics chains once required for transporting paper documents and allows process or equipment changes to be noted immediately and made available across all military services.

A prototype command center allows engineers and military officers to test the interoperability of new technologies and to simulate operational scenarios. Based on existing intelligence gathering and battle management systems, the demonstrator links equipment and provides commanders with real-time data collected from a variety of sensors. Data fusion and decision-making tools permit simulation participants to experience the effects of rapid processing of intelligence information-a clear picture of the battlespace and a shortened sensor-to-shooter loop.
