The new network-centric U.S. Navy, flush with advanced information technologies, can expect greater challenges as it is tasked with more diverse and widespread operations well into the 21st century. Both the Navy and the U.S. Marine Corps will be dealing with major operational issues involving a longer military reach amid greater geopolitical tension and more complex coalition operations. And, both services will be relying on as yet unfielded technologies to fulfill their missions.

The adoption of networked systems and the prevalence of Internet use have created the potential for unauthorized access to critical data. U.S. Defense Department officials believe that uncontrolled Internet connections pose a significant and unacceptable threat to all of their information systems and operations. Ensuring secure transmissions and the authenticity of data while allowing users to connect from remote locations requires high levels of security.

A new method of delivering software promises to reduce the cost and time required for infrastructure setup, software installation, maintenance and support. Known as the application service provider model, the approach reduces the burden on internal information systems resources and enables a predictable cost model for running programs.

The path to Western alliance membership will be paved with silicon if the modernization plan for a former Warsaw Pact nation is successful. The Republic of Bulgaria is looking toward building its revamped military around advanced information systems assembled through U.S. guidance and commercial partnerships.

Profound Internet growth and the changes it generates in the economy and society is a double-edged sword. Electronic commerce benefits are fundamentally altering the way people produce, consume and communicate. Yet, risks and vulnerabilities are inherent network byproducts. Growing electronic threats mandate risk management, customer confidence and at least some level of information protection.

A World Wide Web-based document coordination tool developed for the U.S. Army has become available for the entire federal government. The system enables multiple users to review a directive or regulation posted on a Web or intranet site and enter their comments. The recorded information is then used to modify the document efficiently as it moves toward completion.

The passionate debate about whether to collect sales tax on purchases made over the Internet has politicians, economists and industry searching for the right course of action to continue unprecedented economic growth while supporting the flow of revenue to states or to countries. Experts on both sides of the issue have strong convictions, leaving the legislators with some very hard choices to make during the next several years.

Several months of Russian attacks have shifted the balance of power in Chechnya and changed U.S. thinking about urban warfare. After suffering stunning public defeats just a few years ago, Russian forces applied painful lessons learned then to drive Chechen forces out of their capital city, Grozny, this year. Yet, according to U.S. analysts, this may have merely altered the thrust of battle, not resolved it. And, the tactics employed by both sides are forcing U.S. experts to take another look at the concept of urban warfare.

British forces in Bosnia and Herzegovina and Kosovo will receive a new, highly automated communications network designed to reduce staffing requirements. Part of an ambitious 28-week program by the United Kingdom's Ministry of Defence, it will replace a manpower-intensive system currently in use, allowing roughly 260 Royal Signal Corps personnel to be reassigned. Made entirely from commercial technologies, all elements must be in place and operational by late August before the harsh Balkan winter begins.

Communications specialists are proposing that the U.S. Forces-Korea change engineering and management approaches and follow the lead of commercial Internet service providers. The plan offers wide area network transmission bandwidth between the global defense information infrastructure and command, control, communications, computers and intelligence systems users on the Korean Peninsula, and it addresses several problems with the existing data network there.
