  • Improving SSL Warnings: Comprehension and Adherence

    Conference on Human Factors in Computing Systems 2015 (CHI)

    Browsers warn users when the privacy of an SSL/TLS connection might be at risk. An ideal SSL warning would empower users to make informed decisions and, failing that, guide confused users to safety. Unfortunately, users struggle to understand and often disregard real SSL warnings. We report on the task of designing a new SSL warning, with the goal of improving comprehension and adherence.

    Browsers warn users when the privacy of an SSL/TLS connection might be at risk. An ideal SSL warning would empower users to make informed decisions and, failing that, guide confused users to safety. Unfortunately, users struggle to understand and often disregard real SSL warnings. We report on the task of designing a new SSL warning, with the goal of improving comprehension and adherence. We designed a new SSL warning based on recommendations from warning literature and tested our proposal with microsurveys and a field experiment. We ultimately failed at our goal of a well-understood warning. However, nearly 30% more total users chose to remain safe after seeing our warning. We attribute this success to opinionated design, which promotes safety with visual cues. Subsequently, our proposal was released as the new Google Chrome SSL warning. We raise questions about warning comprehension advice and recommend that other warning designers use opinionated design.

    In December 2014 I was selected to be a Senior Correspondent (4 out of 20 Correspondents were selected for this promotion) based on the quality and diversity of my pieces.

    My article on the Sony Pictures hack was selected as one of Glimpse's "Top 5 Pieces of 2014."
