The rise of software-defined networks and network virtualization has paved the way for micro-segmentation. It’s a security technique that enables fine-grained policies to be assigned to isolated workloads within a data center or cloud deployment. Micro-segmentation is often called a “zero-trust model” of virtualized security, meaning that only necessary actions and connections are specifically enabled in a workload or application, and everything else is blocked. This reduces the network attack surface by limiting east-west communication by applying very granular security controls. The process essentially creates a software-defined workload-level perimeter, regardless of whether it involves a virtual machine (VM), container or function.

Mistake #5: Human Error


Human error has been responsible for some of the biggest disasters in the history of the world. After all, we can’t blame Mother Nature for Chernobyl, global warming, the AMC Gremlin, and New Coke. Those are all tragic events that could have easily been avoided with...
