Although a new and continually evolving field, we have learned a lot about securing systems, and we've defined many of the remaining challenges. Unfortunately, we often find ourselves re-learning the same lessons over and over. In this presentation a number of studies and reports from the past 50 years of infosec will be reviewed and the results examined for the things they show us- both the known and unknown. With the goal of growing infosec beyond our seeming eternal state of infancy, this discussions will embrace some common beliefs and eviscerate others. This talk is intended to spur conversations, reflection, and heavy drinking.
