Hello and welcome to this section on Security in kubernetes.
My name is Mumshad
Mannambeth
and we are going through the Certified Kubernetes Administrators Course. In this section of the course,
we will start with understanding the kubernetes security primitives.
How does someone gain access to the kubernetes cluster and how are their actions controlled etc at a high level.
We then start with the various Authentication mechanisms available.
We will look at the default settings in the cluster and we practice viewing configurations of an existing
cluster.
We discuss about TLS Certificates and how various components within the cluster are secured using TLS
certificates.
If you are a kubernetes administrator and you setup a cluster on your own, you are bound to face challenges
related to certificates. Which is why we discuss these from ground up from the absolute basics.
This is one of the sections that I spent a lot of time on. I wanted to simplify some of the core concepts
around certificates which is why I have added a number of pre-requisite lectures for those who are new
to this topic.
We sent out a poll while working on this section to understand your knowledge about TLS certificates
and most of you said, you were absolute beginners, which is why we thought it would be good to explain
some of these well. Especially since there are so many certificates used within the cluster between various
components and it can be quite confusing for a beginner.
These lectures and the practice test associated with them should help bridge that gap.
But you might have to be a bit patient with me on this.
Our goal is to enable you to tackle any security related or certificate related issues by the end of
this section.
These prerequisite lectures may not be for everyone.
So depending on your level of expertise with certificates.
Feel free to skip some of these lectures as required.
We then move on to authorization. Where we look at the various authorization mechanisms and we focus
specifically on role based access controls.
We then discussed how to secure images in your environment followed by security contacts and finally
network policies.
So a lot of lectures and practice tests coming up.
Take it easy and I hope you enjoy.
