HHS senior Axel Hansen has reached the semifinals in a national science competition for the second time this school year. He is a semifinalist in the Intel Science Talent Search. "This time," Axel says, "I win $1,000 and HHS will also get $1,000 to use." In November Axel reached the semi-finals in the annual Siemens Competition in Math, Science and Technology, but did not win in the finals.

"I used a different research project for this competition," Axel writes. "My paper is titled 'Visualizing Network Anomalies for Intrusion Detection with Information Theoretic Metrics.' The project is to develop a computer program that can detect and visually depict when an attack occurs on a network. It would be useful to mitigate stealthy attacks on any network that has sensitive data or resources. I and my mentor at Dartmouth (Dr. Sergey Bratus) use a statistical technique from information theory to find changes in the 'nature' of network traffic, which can help indicate when and where an attack happens."
