Abstract
As the Internet continues to evolve, it brings a surge of new applications and protocol standards, introducing security and operational challenges. Key questions frequently go unanswered: who is impacted by insecure protocol practices, how widespread such practices are, what operational constraints shape such practices, and where gaps persist between protocol standards and their implementations? We take a data-driven approach towards measuring and uncovering security and operational concerns for Internet protocol usage at scale. In this talk, we focus on protocols related to digital key management, including TLS/PKI and DNS. We then draw on the insights from our data-driven studies to guide the way forward, including holistic investigations on the interactions and needs across stakeholders in the ecosystem.
