The Center for Applied Internet Data Analysis (CAIDA) at SDSC was awarded a $1.4 million grant from the U.S. Department of Homeland Security.

The grant, called “Science of Internet Security: Technology and Experimental Research,” provides funds to CAIDA to expand the scale and capabilities of its secure measurement platform Archipelago (Ark), which supports large-scale active measurement studies of the global internet. The project’s goal is to demonstrate and illuminate structural and dynamic aspects of the internet infrastructure relevant to cybersecurity vulnerabilities, including macroscopic stability and resiliency analyses, grey markets for IPv4 addressing resources, and on-demand router-level topology inference.
