Using Descriptive Statistics to Study the Shape of the Internet


This talk explores applications of descriptive statistical techniques to Censys’ Internet-wide scan data to better understand the shape of the Internet. We’ll compare distributions of various services like HTTP, SSH, and FTP across different ports; examine database exposures and SSH cipher usage; and review trends around popular cloud providers like Amazon, Google, and Microsoft. We’ll also explore seemingly non-existent versions of software, along with other anomalies found in the long tails of these distributions. Finally, we’ll cover how these techniques can lead to more interesting research questions and inform future analyses.
