Secrets of the Encrypted Internet—Worldwide Cryptographic Statistics

David Holmes, Threat Researcher, F5 Networks Key findings from a multiyear, multinode cryptographic scanning project. We sampled tens of millions of Internet hosts since 2014, including every host in the Alexa and OpenDNS Top 1 million to track cipher selection rates, security headers, and fingerprint TLS stacks and web servers for statistical analysis. This talk will present the findings, the scanner architecture and the release of its source code. Learning Objectives: 1: Explore key findings of adoption rates of significant global SSL/TLS trends. 2: Explore the architecture/challenges of a distributed cryptographic TLS scanner. 3: Obtain source code for distributed cryptographic TLS statistic scanner. https://www.rsaconference.com/videos/secrets-of-the-encrypted-internetworldwide-cryptographic-statistics
