Although good things may come in small packages, a handheld device that carries the power of a personal computer raises large information security issues. As more military service members employ cellular telephones, pagers and personal digital assistants to keep track of schedules or to perform duties, their leaders must address the new threats these pocket-sized devices pose in the workplace.

As the Standard Procurement System reaches the installation halfway point, U.S. Defense Department officials are highlighting how the technology makes the department more responsive to Congress and the American taxpayer. Although some personnel are still wary of the new system, the department is forging ahead, and the U.S. Army has adopted additional capabilities that save time and money.

The ongoing revolution in battlefield information systems has generated an intriguing irony. Information technology is empowering individual warfighters far more now than ever before, yet at the same time it is tying them together to an unprecedented degree. On the one hand, soldiers, sailors and airmen are able to serve more roles and to undertake actions of greater significance, as they are both armed with increased amounts of information and capable of providing more vital data to other warfighters and decision makers. On the other hand, these individuals are tied to each other to a greater degree in the network-centric battlefield. As their importance as individuals has increased, so has their importance as nodes in a network. This opens up a host of challenges in areas ranging from technology to doctrine and culture.

U.S. military forces face diverse challenges as they defend national security in the post-Cold-War ear. Dealing with these threats will require both technological solutions and new tactics and techniques. These were some of the views expressed at Tampa TechNet 2001, co-sponsored by the Tampa-St. Petersburg Chapter and AFCEA International.

A security management system allows administrators to track computer network threats by providing near-real-time alerts from remote sensors on the network. Software agents, tailored to be expert monitors of specific programs and devices, use rules sets to sift through data before sending reports to a central management engine that tracks and correlates the information. Thousands of potential alerts then are analyzed and reduced to one or two dozen incidents that require immediate attention.

Autonomous underwater vehicles, unmanned aircraft and miniature tracked vehicles all rigged with enhanced mine-detecting capabilities will assess a dangerous area before troops disembark from ships, providing them with information about what lies beneath. Outfitting battle groups with these relatively small yet powerful technologies will allow them to conduct mine countermeasures independently so that amphibious units can proceed quickly with their missions.

Submariners are being immersed in the latest in simulation technology to familiarize them with their future stations and duties. Hardware and software under development during the past few years have come to fruition, and instructors at the U.S. Naval Submarine School, Groton, Connecticut, are excited about the positive impact the new systems have in their classrooms. Students are so excited about training in this fashion that they actually refuse to leave when the final bell rings.

The U.S. Army is developing cutting-edge simulation technologies that will allow soldiers to train in a variety of simulated environments. In partnership with the entertainment industry, the service is designing highly realistic and interactive instructional systems that blur the line between contemporary computer-based instruction and science fiction.

The U.S. Defense Department's prime modeling and simulation office is crafting a new master plan that focuses on warfighter needs rather than technological leaps. The plan is emerging from a reassessment of past accomplishments as well as requirements identified by the major commands.

This month marks the beginning of the future of defense science in the United Kingdom as the Ministry of Defence breaks with long-standing custom and transfers the bulk of its research to the commercial sector. The newly formed corporate vehicle for this transformation will be required to sink or swim in the marketplace to maintain its viability as a font of technology innovation.
