With peta-bytes of data that are continuously collected about various aspects of the Internet, how hard can it be to obtain an accurate picture of its traffic, its physical topology (i.e., router-level Internet), its logical overlays (e.g., the Web, online social networks), or its “dark” sides and associated activities (i.e. cyber crimes)? In this talk, I will first use some well-known examples of “big (Internet) data” to illustrate what this data does and doesn’t tell us about the Internet’s traffic and its physical topology. Moving on to the problem of cyber security, I will then discuss why and how future Internet measurement studies have to change so that the much-heralded “big data” approach to Internet research can achieve its full potential.
