• Exploiting concurrency in large-scale botnet detection

    Prof. Nagaraja is engaged in research into P2P botnets made famous yet
    again by post-wikileaks network attacks. His group seeks to understand
    the fundamental limits of the P2P technologies used as botnet
    foundations and design effective botnet countermeasures. The IBM X10
    award will continue to fund research in this direction. The
    understanding of efficiency, robustness and resilience to attacks of
    various decentralised botnet architectures along with development of
    novel techniques that will deal with the sea of uncertainty that comes
    from building a system out of unreliable and sometimes untrustworthy
    components will be game changing initiatives in dealing with the
    problem of botnet defense. A significant component of this work is
    large-scale statistical traffic analysis dealing with terabytes of
    traffic on a daily basis. The IBM X10 award will fund a specific part
    of his group's research agenda on developing concurrent techniques for
    performing such analysis on ISP scale traffic. Specifically, on
    spatial and temporal communication pattern analysis and understanding
    botnet structure. The development of such highly concurrent large
    scale systems will play a key role in engendering cooperative
    cooperative detection of botnets in the near future.
