Army Signal Expands Its Reach

September 1, 2013
By Robert K. Ackerman

The U.S. Army Signal Corps is expanding the work its personnel conduct while dealing with technology and operational challenges that both help and hinder its efforts. On the surface, Army signal is facing the common dilemma afflicting many other military specialties—it must do more with fewer resources.

Bringing Together Signal and Cyber

September 1, 2013
By Paul A. Strassmann

In his June interview with SIGNAL Magazine, Gen. Keith B. Alexander advocated bringing together the signal community, signals intelligence and the cyber community. In that interview, he said, “We need to think of ourselves not as signals, not as intelligence, not as cyber, but instead as a team that puts us all together.” Yet, that goal raises several questions. How can these concepts be achieved? How can a combination of more than 15,000 system enclaves from the U.S. Army, Navy, Marine Corps and Air Force become interoperable? What technologies are needed in the next five years while insufficient budgets make consolidations difficult?

Open Data Initiative: Providing Fresh Ideas on Securely Sharing Information

August 30, 2013
By Paul Christman and Jamie Manuel

For years, the Defense department took a “do it alone” posture when it came to sharing information and protecting its networks and communication infrastructures from security attacks. Now in an interconnected world of reduced budgets and ever-increasing security risks, the DOD is fundamentally changing the way it approaches information sharing and cybersecurity. 

White House Cyber Policy Focuses on Internal Consolidation, External Engagement

August 21, 2013
By Henry Kenyon

As a part of its ongoing efforts to protect critical national infrastructure, the Obama administration has been actively working on making government computer networks more robust and resistant to cyber attack. To do this, the White House has looked internally at federal agencies to put into place new metrics and policies to improve their security stance and externally, reaching out to foreign governments to set up international accords on cyber espionage, a top administration official said.
 
The administration has several major priorities for its cyberspace policy: protecting critical infrastructure, securing the government, engaging internationally, and shaping the future, explained Andy Ozment, the White House’s senior director for cybersecurity.
 
Speaking at the USENIX Security Symposium in Washington D.C., on August 15, he said that as part of its overall cyberspace goals, the Obama administration is actively pursuing international engagement and cooperation. This is a necessity as most cyberspace intrusions come from overseas, he said, adding that it also touches on diplomatic issues. This is because the term “attack” has a number of political implications that can potentially lead to direct conflict with a nation. On the other hand, intrusions fall under the category of espionage, an area where there are well established protocols for working with other nations, he said.
 

Tech Transfer Thrives

August 20, 2013

 

Investors, integrators and information technology companies this week will see eight government-developed emerging cybersecurity technologies ready for transition into the commercial sector. Capabilities to be unveiled include intrusion detection, removable media protection, software assurance and malware forensics. The technology demonstration day, which takes place in San José, California, on August 22, gives investors and the business sector the opportunity to view laboratory prototypes of the cybersecurity products in action.

Michael Pozmantier, program manager, Transition-to-Practice, Science and Technology Directorate, U.S. Department of Homeland Security, and technology developers from the U.S. Department of Energy’s national laboratories will be on hand to discuss the capabilities and their potential.

Transition-to-Practice events are held several times a year at locations around the United States.

Incentivizing Companies to Manage Cyber Risks Better

August 9, 2013

 

The White House is developing a core of practices to develop capabilities to manage cybersecurity risk. This Cybersecurity Framework will be available in draft form in October and finalized in February 2014. At that time, officials will create the Voluntary Program to encourage critical infrastructure companies to adopt the framework. Until then, the government is looking at ways to incentivize companies to participate. Some recommended incentives can be adopted quickly while others will require legislative action and additional work. The White House is collaborating with appropriate agencies now to move forward and to prioritize incentive areas including cybersecurity insurance, grants, process preference, liability limitation, streamlined regulations, public recognition, rate recovery for price regulated industry and cybersecurity research.

AFCEA Answers: GSA’s McClure Cites Two Factors for Security in the Cloud

August 5, 2013
By Max Cacas

When it comes to cloud computing, there are two items that are top of mind for Dave McClure, Associate Administrator with the General Services Administration (GSA) in Washington, D.C.
 
“One is boundaries. Where does a cloud service provider’s authorization and control begin and end?” he noted on a recent edition of the “AFCEA Answers” radio show. McClure goes on to explain that while an infrastructure provider might have a given set of controls and responsibilities, there are software applications that, as he puts it, “sit on top of that infrastructure. Who owns the apps, and who is responsible for security in the application space?”
 
McClure, who has had a long career in information technology in both the private sector and government, suggests that the other challenging security area in today’s cloud computing environment deals with defining the business side of cloud. “There’s some confusion between security controls and contractual terms that deal with access issues, location issues, and usage, some of which are contract, more than straight security concerns. Getting all of that right—the boundaries, the authentication piece, the contract piece—there’s definitely a lot to pay attention to in the cloud space.”
 
Edwin Elmore, Cloud Computing Business Development Manager with Cisco Systems in Washington, sees the challenge of security in the cloud as one of “taking the physical world and moving it to the virtualized world. When you look at cloud computing, it’s a heavily virtualized environment, so the same controls you have around a physical perimeter in your physical data center, now you have to extend it to the virtualized world.” And that, he says, includes applying the same security protocols when it comes to virtual machines exchanging data with each other.
 

Software Increases 
Unmanned Craft Survivability

August 1, 2013
By George I. Seffers and Robert K. Ackerman

 

The U.S. Defense Advanced Research Projects Agency is developing new control software to reduce the vulnerability of unmanned systems to cyber attack. This effort is relying on new methods of software development that would eliminate many of the problems inherent in generating high-assurance software.

Unmanned vehicles suffer from the same vulnerabilities as other networked information systems. But, in addition to their data being co-opted, unmanned systems can be purloined if adversaries seize control of them. This problem also applies to human-crewed systems with computer-controlled components.

If the research program is successful, then unmanned vehicles will be less likely to be taken over by an enemy. Warfighters could trust that the unmanned vehicle on which they are relying will not abandon its mission or become a digital turncoat.

This security would extend to other vulnerable systems as well. Networked platforms and entities ranging from automobiles to supervisory control and data acquisition (SCADA) systems could benefit from the research. The vulnerability of SCADA systems is well-established, but only recently has research shown that automobiles can be co-opted through their computer-controlled systems. The program’s goal is to produce high-assurance software for military unmanned vehicles and then enable its transfer to industry for commercial uses.

The Defense Advanced Research Projects Agency (DARPA) program is known as High-Assurance Cyber Military Systems, or HACMS. Kathleen Fisher, HACMS program manager, says the program is aiming to produce software that is “functionally correct and satisfying safety and security policies.

“It’s not just that you’re proving the absence of a particular bad property from the security perspective,” she explains. “You’re actually positively proving that the software has the correct behavior.”

Building
 a Bigger,
 Better Pipe

Scientists at the U.S. Defense Department’s top research and development agency are seeking the best new ideas to provide a larger-scale mobile network to support an increasing array of bandwidth-hungry mobile computing devices for warfighters.

The Defense Advanced Research Projects Agency (DARPA) has issued a Request for Information (RFI) for new technical approaches that would expand the number and capacity of Mobile Ad Hoc Networks (MANETs) nodes available in the field.

“When we look at MANETs, it’s really tough to deliver networking services to more than about 100 users,” says Mark Rich, program manager, DARPA Strategic Technology Office. Those 100 users translate into approximately 50 nodes on a mobile wireless network operating in a forward location, generally supporting everything from tactical and operational systems to advanced video services. All of these functions are carried on a service that is largely dependent on highly secure digital radio systems. Once that limit is reached, network services begin to deteriorate in quality and effectiveness. To support larger deployments or to cover a greater area, military communications experts usually knit smaller networks using other available means, such as satellites.

Marines Set the Stage for Next-Generation Network

August 1, 2013

The steady march toward the U.S. Navy’s Next-Generation Enterprise Network underwent a leap ahead as the U.S. Marines undertook a full transition before the contract for the new system even was awarded. The multiyear effort saw the Corps methodically absorb functions of the Navy/Marine Corps Intranet predecessor so the service was positioned for a smooth adoption of the new network.

This shift to a government-owned network required more than just a change in direction. The Corps had to achieve the transition without allowing any break in services to its Marines concurrent with deployments to Southwest Asia. It had to move network operations seamlessly across a philosophical gulf as well as a logistical one without creating a new infrastructure. And, it had to finish the transition perfectly positioned for the incorporation of the Next-Generation Enterprise Network, or NGEN.

By design, the transition planners had to aim at a hidden target. The entire transition took place before the contract for NGEN was awarded (see page 53), so they had no idea what the network would resemble. They needed to estimate what the winning bidder—whichever team it would be—would configure as a cost-effective, government-owned and -operated enterprise network. Then, the planners had to design a transition that would lead the Corps to that envisioned destination without losing any functionality along the way.

On June 1, the multiyear effort largely was completed. Brig. Gen. Kevin J. Nally, USMC, director of Command, Control, Communications and Computers (C4) and chief information officer (CIO) for the Marine Corps, lauds the results. “The transition effort went very, very well,” he states, crediting the skill of the personnel involved for its successful outcome. Their knowledge, as well as their ability to adapt and overcome hurdles, were key to the transition program.
