Abstract

As the Internet continues to emerge as a critical information infrastructure, IT early warning systems (IT-EWS) have taken on greater importance in protecting both its endpoints and the infrastructure itself. Although it is generally accepted that open sharing of cyber data and warnings between the independent (but mutually vulnerable) endpoints promotes broader situational awareness, such openness introduces new privacy challenges. In this paper, we present a high-level model for security information sharing between autonomous operators on the Internet that enables meaningful collaboration while addressing the enduring privacy and infrastructure needs of those individual collaborators. Our concept for a collaborative and decentralised IT-EWS is based on a novel combination of existing techniques, including peer-to-peer networking and Traceable Anonymous Certificates. We concentrate on the security and confidentiality of the data exchange platform rather than of the data itself, a separate area of research.
