It’s hard to ignore Kubernetes nowadays when discussing container orchestration thanks to its robustness and comprehensive features. It is capable of supporting even the most complex apps and services. Despite the wealth of features built into Kubernetes, the platform only provides a set of built-in authentication and authorization mechanisms which all administrators can configure and use—the thing is, in the information security world, this is not enough. You need to optimize security yourself to take it next level.
With security becoming a primary concern in cloud deployment, knowing how to secure Kubernetes properly is a must. Putting a firewall layer on the host cluster is simply not enough, even though taking care of host security across all servers running Kubernetes containers can help.
