The information technology industry is increasingly directing its efforts to commercial security requirements and less so to those of government. The result is that the private sector is overtaking its government counterpart in maintaining computer network security.

Protecting electronic commerce on the Internet is a very secretive and unforgiving business. Robust security, however, is pivotal to its phenomenal expansion as networks surge toward a $200 billion market within the next two years. This demand for vigorous network refuge is creating a $6 billion worldwide security industry market, growing at a rate of more than 50 percent a year.

The Internal Revenue Service is adopting a mission-oriented approach to designing its new agencywide information infrastructure. Instead of focusing on information technology, the modernized system will be business-centered to ensure that it directly addresses the agency's requirement to manage mountains of data while collecting over $1 trillion in annual tax revenues.

Federal agencies with specialized image archival requirements are meeting their storage and retrieval needs by maximizing the capabilities of software first used by Hollywood's entertainment industry. Government organizations with large image databases can use this software, which employs innovative search techniques, to help analysts sift through incalculable amounts of digital information. The software eliminates typical problems involved in tracking important reference material and can assist agencies by also housing information gathered from analysis of image files.

Organizations that rely on large amounts of data are increasingly employing data cleansing techniques to ensure accuracy and efficiency by scrubbing data that has been polluted at the source or on its way to a data warehouse.

Data visualization, where information is displayed in recognizable graphic elements, increasingly is moving into mainstream applications as a remedy for information overload. As computer users find growing amounts of gigabytes at their fingertips, system engineers are returning display perspectives to everyday three-dimensional visages that are comprehended faster and more readily.

As Alvin Toffler predicted almost 30 years ago, society is transitioning from its second wave, the industrial revolution, to the third wave, the information age. All three waves, beginning with the agrarian age, offered their own elements of control that proved vital to prevailing economically and politically. In the first wave, the objective in the agrarian society was to control the land from which life-giving food would be harvested. In the industrial second wave, the objective was to control the means of production. Now, in the information age, the objective is to control the information technology.

Semiconductor designers are increasing their dependence on computer-aided design and testing to advance microcircuitry beyond the current state of the art. Demand for more and more complex chips has necessitated taking design out of the hands of engineers and into the realm of cyberspace.

A simulation tool that creates a virtual satellite allows ground personnel to rehearse satellite communications and operations disciplines without tying up valuable orbiters. The new system enables warfighters to train on, assess and certify orbital communications links without interrupting ongoing satellite operations.

New very high frequency radios are sharing the airwaves with sensor systems in battlefield networking. Both communications and radar units have become portable enough that they now are mobile nodes in an interlocking information web.
