This talk covers the key lessons learned and root causes from
the biggest mega-breaches and the 9,000+ reported breaches over the
past 15 years.  By analyzing the histories, stories, and deep dives
of breaches such as those at Target, JPMorganChase, OPM, Yahoo,
Equifax, Facebook, Marriott, Capital One, and the SolarWinds hack,
I will also lay the groundwork for a roadmap to recovery based on
the root causes.
