What Is A Zero Trust Network Architecture

Every few years the industry takes a significant step towards a more holistic and capable security model. At the beginning, everything and everyone was trusted, and for good reason. You knew every operator and every machine that was connected to the network. But as networks have become ubiquitous, that level of trust is simply unreasonable. So we’ve built firewalls, and differing levels of inspection, but all of these tools still allow for some implicit level of trust between a machine and those machines closest to them. That is changing and that is what we’re here to talk about today. The newest trend in security is the concept of zero trust, and while it’s suffering the common plight of any new trend with multiple vendors trying to shape the definition, removing implicit trust in our networks is the next logical step towards a truly secure infrastructure.
