Summary

mapping our way to a more secure Internet (k claffy)

abstract

Today the "cyber threat" is one of our most serious economic and national security challenges. But our lack of empirically grounded understanding of the structure, dynamics, and scope of vulnerabilities of the global Internet renders this challenge virtually intractable. In this talk, we examine the emerging field of cyber-cartography: what kind of maps of the Internet do we need, and what problems do they solve? What capabilities are required to construct which maps, and what blocks progress on development of these capabilities? We'll provide examples of applied mapping research and development activities at various levels of maturity, including those that support detection of Internet security and stability weaknesses. By the end of this talk you will learn at least five ways that you personally can participate in the field of cybercartography.

Software Systems for Surveying Spoofing Susceptibility (Matthew Luckie)

abstract:

Despite source IP address spoofing being a known vulnerability for at least 25 years, and despite many efforts to shed light on the problem, spoofing remains a viable attack method for redirection, amplification, and anonymity. The goal of the CAIDA spoofer project is to increase the density of crowd-sourced measurement of ingress filtering, and publicly provide evidence of where remediation attention should be focused. In this talk, I will discuss the new measurement system we developed, present the public reporting website, report on remediation and outreach efforts, and discuss lessons learned.

A Look at Router Geolocation in Public and Commercial Databases (Bradley Huffaker)

abstract

Internet measurement research frequently needs to map infrastructure components, such as routers, to their physical locations. Although public and commercial geolocation services are often used for this purpose, their accuracy when applied to network infrastructure has not been sufficiently assessed. Prior work focused on evaluating the overall accuracy of geolocation databases, which is dominated by their performance on end-user IP addresses. In this work, we evaluate the reliability of router geolocation in databases. We use a dataset of about 1.64M router interface IP addresses extracted from the CAIDA Ark dataset to examine the country- and city-level coverage and consistency of popular public and commercial geolocation databases. We also create and provide a ground-truth dataset of 16,586 router interface IP addresses and their city-level locations, and use it to evaluate the databases’ a curacy with a regional breakdown analysis. Our results show that the databases are not reliable for geolocating routers and that there is room to improve their country- and city-level accuracy. Based on our results, we present a set of recommendations to researchers concerning the use of geolocation databases to geolocate routers.
