The Arrival of Zero Trust: What Does it Mean?

Abstract

It used to be that enterprise cybersecurity was all castle and moat. First, secure the perimeter and then, in terms of what went on inside that, Trust, but verify. The perimeter, of course, was the corporate network. But what does that even mean at this point? With most employees now working from home at least some of the time and organizations relying increasingly on cloud computing, there is no such thing as a single, enterprise-wide perimeter anymore. And, with corporate security breaches having become a regular news item over the past two decades, trust has essentially evaporated as well.
