Duke University Research Could Improve X-ray Screening at Airports

Two Duke University professors might be radically changing for the better how Americans get through airport security.

David Brady, a professor of photonics, and Stephen Mitroff, an associate professor of psychology and neuroscience, have been developing a new system that identifies the molecular structure of items passengers carry onboard.

“Now, rather than just saying something is metal or non-metal,” Brady said, “we have tungsten and lead, and we can identify, specifically, all of those different materials.”

The idea, he said, is to make machines sensitive to specific materials based on specific threats.

That means passengers who long for the days of carrying their own shampoo, toothpaste and mouthwash in containers of more than 3 ounces without creating a national incident may get their chance.

These new X-rays have implications in the medical field, Brady said. His new system emits rays that are more focused.

“The trade-off with medical screening is always a balance between how much cancer you cause with an X-ray screening versus how much you detect,” Brady said “And so by reducing dosage you make it easier to do X-ray screening.”

Brady hopes to see his X-ray technology in airports in 18 months to two years.

Virtualization and Data Center Security: What You Need to Know for 2014

Data centers are increasingly becoming the center of the enterprise, and data center and cyber security is following the same path for security departments. According to Justin Flynn, a consultant at the Burwood Group, the virtualization of data centers allows enterprises to scale more easily and faster, with a smaller footprint.

However, hosting enterprise data in the cloud can make intrusion detection more difficult – how can enterprise security leaders team up with other departments to keep aware of cyber risks and traffic, and physical and data compliance during the virtual transition? How can CISOs and CSOs discuss cyber threats with the C-Suite to get the resources they need? And how can the proper infrastructure test and verify possible malicious attacks?
