Today hackers disguise their attacks by launching
them form a set of compromised hosts distributed
across the Internet. It is very di#cult to defend
against these attacks or to track down their origin.
Commercially available intrusion detection systems
can signal the occurrence of limited known types of at
tacks. New types of attacks are launched regularly but
these tools are not e#ective in detecting them. Human
experts are still the key tool for identifying, tracking,
and disabling new attacks. Often this involves experts
from many organizations working together to share
their observations, hypothesis, and attack signatures.
Unfortunately, today these experts have few tools that
help them to automate this process.
In this project we recognize that human experts
