Safety-I and Safety-II are two views of what makes a system safe, where Safety-II is a more modern and proactive view of safety that has driven record safety in the airline industry. For comparison, Safety-I defines safety as "as few things as possible go wrong" while Safety-II defines safety as "as many things as possible go right." Safety-I also categorizes the human factor as a hazard or liability, while Safety-II categorizes the human factor as necessary for system resilience.

I tell ya hwat, I don't think most of the #InfoSec field is ready for a Safety-II mindset. Just look at how differently the human factor is considered in Safety-I and Safety-II ... that certainly rings a bell with all the user-blaming I've seen :/
Maybe someday.
