Extracting signatures and filters for Zero-day sophisticated DNS and other DDoS attacks

Prof. Afek Yehuda and Prof. Anat BremlerBarr

In the past three years the first two PIs with their students have developed algorithms for zero-day signature extraction for html based DDoS attacks, and the goal of this proposal is to extend this work in several directions.  The proposal will entail the development of new algorithms for the analysis of high throughput streaming data (aka big data) to detect heavy hitters with high distinct counts that were not such at peace time (i.e., are very likely malicious and not legitimate).
