Two decades ago, my life changed forever: hearing #BruceSchneier explain that "#security" doesn't exist in the abstract. You can only be secure *from some threat*. A fire alarm won't protect you from burglaries. A condom won't protect you from mass shootings. It seems obvious, but how often do we hear about "security" without any mention of *who* is being made secure, and from *which* threat?
