U.S. Army communications facilities in Okinawa, Japan, are using an automated alarm management system to monitor legacy equipment that is not interoperable. Consisting of an easily installed remote unit and management software, the system permits administrators to control multiple proprietary devices from a single on-screen interface.

One of the key factors inhibiting the growth of the wireless fidelity market is security. The attractive wireless technology that offers a wide range of applications also is generating a wave of uncertainty about the fidelity of its connectivity.

A review of U.S. Defense Department information systems using a code analysis process has found no evidence of deliberate infusion of vulnerabilities into applications, but it has found instances of bad coding practices and programmer shortcuts that have left systems open to attack. The vulnerabilities found would not have been easily detected by an outside source, but they were open doors for an insider who wished to exploit them. The systems were hosted on extremely critical networks where a breach could have catastrophic consequences.

An increasing emphasis on information security is prompting experts in the technology industry to follow the lead of the medical and legal professions, which feature a system of specialties and subspecialties. One major accreditation organization is taking a closer look at the government sector and addressing the distinct circumstances of information security specialists in that arena. Once specific issues are identified, they could affect the certification process as well as influence public policy.

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.
