The traditional 3-tier data center architecture model continues to challenge security professionals who are tasked with embracing a highly mobile workforce. I and many others were taught years ago that we must design an onion like perimeter that has a trusted user base and critical data living inside a well-protected perimeter. Forrester turned this model on its head when they coined the term “Zero Trust” in a report published in 2010. I prefer not to speak in absolutes, so I’ll proposed an alternate, more flexible approach to implementing the Zero Trust methodology. Instead of eating the elephant, I’ll show how implementing bite sized portions of the Zero Trust model will help future proof your organization against challenges such as BYOD, SaaS offerings, Cloud hosted resources, mobile workers, and the ever increasing compliance requirements on segmentation.
