Summary

In this chapter, we covered how to harden a container image with CIS Docker benchmarks, and then we gave a detailed introduction to the security attributes of Kubernetes workloads. Next, we looked at the PodSecurityPolicy in detail and introduced the kube-psp-advisor open source tool, which facilitates the establishment of pod security policies.

Securing Kubernetes workloads is not a one-shot thing. Security controls need to be applied from the build, deployment, and runtime stages. It starts with hardening container images, and then configuring security attributes of Kubernetes workloads in a secure way. This happens at the build stage. It is also important to build adaptive pod security policies for different Kubernetes workloads. The goal is to restrict most of the workloads to run with limited privileges, while allowing only a few workloads to run with extra privileges, and without breaking workload availability. This happens at the runtime stage. kube-psp-advisor is...
