Research is extending the boundaries of information assurance technology to include the operational reliability of individual systems and the ability of tactical wireless networks to remain secure. Scientists are developing agile solutions to counter new types of cyberassaults and to protect vulnerabilities detected in emerging technologies.

The United States has recruited private industry to help fight the war on terrorism on the home front. The next battlefield may be cyberspace, and the government is working with its operators to protect and defend crucial assets in that realm against attacks that could potentially cripple the country.

The challenge of providing secure information is not new. Since the early days of computer networking, we have been striving to ensure the sanctity of bits and bytes. As computer and communications technologies advanced exponentially, so did the security challenges facing our information community. Now, information systems are everywhere and have become essential elements in the daily operations of industry, civil government, the intelligence community and military forces.

A recently developed identification authentication system permits personnel to receive single-use passwords via wireless devices, allowing users who are traveling or at remote sites to access their networks. The technology is compatible with a variety of equipment that supports text messaging such as cellular telephones, pagers, personal digital assistants and laptop computers.

The U.S. Air Force's toughest opponent in its mission to maintain air supremacy may be the march of time. Its aircraft are flying more hours and serving well past their original service lifetimes, and new network-centric operations are impelling technology upgrade across all wings.

A new U.S. Air Force organization will conduct base maintenance, logistics and communications systems operations as part of a broader restructuring of the service's capabilities. It will work closely with the commands to provide essential services such as electronic records management and databases, information assurance for military operations and force structure, and organizational issues analysis.

Smaller proved to be better for U.S. Air Force special operations forces that were inserted into Afghanistan. The smaller aspect was in the reduced communications footprint that allowed small teams to quickly begin operations in remote hostile territory. The better element was the advanced communications and situational awareness capabilities that were established well before the entry of conventional forces.

Buoyed by pinpoint impact and target destruction of successive ballistic missile test warheads in space, the U.S. Navy and the Missile Defense Agency are moving to more difficult engagement scenarios. This sea-based element of ballistic missile defense builds on the existing Aegis weapon control system and Standard Missile infrastructure to extend battlespace.

A group of Russian telecommunications scientists has developed a new technology that can serve as a backbone for today's multiple communications protocols or as a stand-alone network. It can be scaled from a local area network up to a global telecommunications system capable of carrying voice, data and video simultaneously.

The software programmable radio era has spawned a new generation of units designed to interoperate while simultaneously serving specific service and platform needs. The result of these digital genetics is instant interoperability among land, sea and air forces as well as software-driven upgrades and compatibility with other systems.
