As more complicated networks develop and deploy unique and expanded capabilities, protecting U.S. cyber infrastructure grows more challenging. The Department of Homeland Security’s National Protection and Programs Directorate is responsible for defending the nation’s commercial and private networks. But with the complexity of these products, the directorate’s success increasingly depends both on sharing responsibilities among government organizations and between government and industry.

You may remember that old New Orleans house I mentioned in a previous column and its ongoing renovation that so closely matches the process of upgrading legacy federal information technology systems. The house was built in 1890, by true artisans, with thick plaster walls, joists made out of solid red pine or cypress, a slate roof, ornate ironwork, thick wooden floors, nine monstrous fireplaces and all the supporting brickwork that was certainly made for beauty, functionality and durability. However, it was not made for wireless networks, sound systems or any other type of technology innovation.

A lightweight robot that can leap more than 20 feet horizontally and vertically could be fielded within a year if funding is made available. By enhancing situational awareness during urban combat operations, the robot has the potential to lower casualties both for civilians and for friendly forces fighting their way through a city environment.

Evolving technologies such as mobile devices, cloud computing and steganography present challenges for those tasked with finding digital evidence of a crime. But the cyber forensics field also is evolving, and experts in industry and government are finding innovative tools for overcoming the obstacles.

U.S. Navy researchers have built a prototypical family of small, simple and affordable unmanned aerial vehicles that warfighters can use to deploy an array of sensors, tailor for a variety of missions, and launch by ones and twos or by the thousands. Essentially a flying circuit board, the miniature craft has completed basic research and development and is ready for further technological advances and eventual battlefield deployment.

I am late with this November edition because of some ongoing changes in my professional life that are of no great importance to any of you, but could impact the Social Security Administration.

The U.S. intelligence community faces the possibility of devastating budget cuts if the congressional Joint Select Committee on Deficit Reduction does not reach an agreement by November 23, 2011. The community is not ready for the massive reductions that would be imposed if that congressional committee fails to reach agreement, says a senior defense official.

Here’s an interesting look into the inner workings of international cyber criminals by virtue of covertly recorded conversation snippets. The characteristics of similar processes in Western governments, particularly here in the United States, are well known because they are described in detail in the media. Our processes exist to provide accountability, budget constraint, quality assurance and fair competition. The bad guys have a slightly different take on how to go about things.

The U.S. Coast Guard 1st District is making plans to extend its network of disparate yet connected radio frequencies down to its front lines. If all goes according to plan, the smaller, lighter technology could make its way into the vests of boarding-team leaders, giving them the ability to connect with higher headquarters via not only voice, but also full-motion video and videoteleconferencing.

Every meeting should have a specific objective: make a decision, plan a strategy or brainstorm ideas.
