Kubernetes was not famous for its security features when it was first introduced as a container orchestration system, but the platform has evolved a lot over the years. Aside from being portable and infrastructure-agnostic, Kubernetes also offers a wide range of security features and tools that can help you harden the security of your apps and services.

Pod security is one of the ways you can safeguard your entire cloud ecosystem. Kubernetes Pod Security Policies are basically a series of policies that govern how Pods interact with the host operating system and other resources within the cluster. It defines the conditions under which Pods are allowed to run and use cluster resources.

Kubernetes Pod Security Policies will act as the controller that allows the creation and update and Pods within the cluster. You start by defining a set of rules for the pods and then activate the controller so that new and updated Pods are checked against those rules.
