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.
