Large Scale Collection and Sanitization of Network Security Data: Risks and Challenges
Tuesday, September 26, 2006
"Over the last several years, there has been an emerging interest in the development of wide-area data collection and analysis centers to help identify, track, and formulate responses to the ever-growing number of coordinated attacks and malware infections that plague computer networks worldwide. As large-scale network threats continue to evolve in sophistication and extend to widely deployed applications, we expect that interest in collaborative security monitoring infrastructures will continue to grow, because such attacks may not be easily diagnosed from a single point in the network. The intent of this position paper is not to argue the necessity of Internet-scale security data sharing infrastructures, as there is ample research [13, 48, 51, 54, 41, 47, 42] and operational examples [43, 17, 32, 53] that already make this case. Instead, we observe that these well-intended activities raise a unique set of risks and challenges.
We outline some of the most salient issues faced by global network security centers, survey proposed defense mechanisms, and pose several research challenges to the computer security community. We hope that this position paper will serve as a stimulus to spur groundbreaking new research in protection and analysis technologies that can facilitate the collaborative sharing of network security data while keeping data contributors safe and secure."
