Genetics Inspired Research Prevents Cyber Attacks

16.02.2012
Cyber security is an ever changing and growing concern. Nearly twice as much cyber security funding proposed in the 2013 budget underscores the need for improved computer network defenses. Inadequate security configurations are blamed for 80 percent of the United States Air Force network vulnerabilities.

Now Wake Forest University researchers are fighting the continual evolution of viruses, worms and malware with evolution by developing the first-ever automated computer configurations that adjust as quickly as the threats.

Computer Science Associate Professor Errin Fulp and graduate student Michael Crouse are refining a genetically inspired algorithm that proactively discovers more secure computer configurations by leveraging the concept of “survival of the fittest.” Early simulations have shown the increased diversity of each device’s configuration improves overall network safety, without putting undue stress on IT administrators.

“Typically, administrators configure hundreds and sometimes thousands of machines the same way, meaning a virus that infects one could affect any computer on the same network,” says Crouse, who recently was named one of the “nation’s top new inventors” by Inventor’s Digest magazine. “If successful, automating the ability to ward off attacks could play a crucial role in protecting highly sensitive data within large organizations.”

Funded by a grant from Pacific Northwest National Laboratory (PNNL), the researchers aim to improve defense mechanisms of similar computing infrastructures with minimal human interaction.

Cyber attacks usually take place in two phases, says Fulp. In the reconnaissance phase, a virus simply observes the landscape, identifies possible defense mechanisms and looks for the best way in. If nothing has changed since the reconnaissance phase upon return, the virus strikes. But security experts say even the slightest change in environment can make a huge difference in deterring potential attackers.

“If we can automatically change the landscape by adding the technological equivalent of security cameras or additional lighting, the resulting uncertainty will lower the risk of attack,” explains Fulp.

Researchers are currently testing their work to transform cyber security. Planned assessment includes integrating the automated system into the computer science department’s annual “hackathon,” giving budding developers the opportunity to improve the system.

Though no one has successfully modeled this complex process before, this is not the first time Fulp and Crouse have turned to nature to guide their research. Read more about their bio-inspired projects to improve cyber security at http://go.wfu.edu/bioinspiration.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
