Abstract:
In this paper we propose an architecture for using
cross-organization information sharing to identify members of a
group of hosts enslaved for malicious purposes on the Internet.
We root our system in so-called ``detectives''---savvy network
monitors like sophisticated intrusion detection systems or
honeyfarms that have a deep understanding of malicious behavior.
We augment information from these detectives with observations
from a large array of ``witnesses'' that are already in-place at
many locations in the network. These witnesses are not savvy
enough to understand that a particular behavior is malicious, but
their simple factual observations can be shared with a detective
in order to form a broad picture of a group of bad actors. A key
aspect of the system is the design of a lightweight mechanism to
reliably share enough information between detectives and witnesses
to form an understanding of a group of bad actors without sharing
more information than necessary, in order to address privacy and
competitive concerns.
