Interactive Graph of Relationships Between Root and Intermediate Certificate Authorities Is Released, Featured on SlashDot

December 17, 2012
An interactive graph created by DAAD postdoctoral fellow Johanna Amann shows the relationships between root and intermediate certificate authorities (CAs) of institutions around the world. The graph was featured on SlashDot. Amann extracted from each certificate chain the path of intermediate CAs up to the root and then merged all paths into a graph. Amann works in the Networking and Security Group.

New Service Checks Users' SSL Certificates

November 7, 2012
Networking Group researchers have made available a new service that provides near real-time reputation information on TLS/SSL certificates. The ICSI Certificate Notary improves the security of users' Internet activity by allowing clients to compare certificates they encounter while browsing the Web against a third-party database. Such checks help avoid man-in-the-middle attacks where an adversary assumes the identity of a well-known secure site (for example, a bank or email provider) by serving a malicious certificate.

NSF Awards $10 Million Grant to ICSI and Collaborators to Study Human Element of Cybercrime

September 25, 2012
ICSI, the University of California, San Diego, and George Mason University have received a $10 million, five-year grant from the National Science Foundation to investigate the roles played by economics and social interactions in Internet security. While security research has tended to focus on the technologies that enable and defend against attacks, the new project emphasizes the profits that motivate the majority of Internet attacks, the elaborate marketplaces that support them, and the relationships among cybercriminals, who rely upon each other for services and expertise.
