Kubernetes Security: Missing Network Segmentation Controls
Introduction
Kubernetes has numerous layers for communication, and providing security across all of those layers is a difficult task. One of the challenges is the establishment of an isolating environment in which clusters, pods, and namespaces can communicate with one another. All of this is possible with the correct implementation of a network on Kubernetes; however, because Kubernetes employs a flat network topology, there is no need to map the resources, and faster communication may be provided among dispersed systems while machines are shared among applications. Let’s get into further detail about that.
What is Kubernetes Networking?
In order for components to communicate with one another, Kubernetes makes use of networking. The networking in Kubernetes is built on a flat network topology, which means that rather than needing a lot of switches, users can just use one. This will assist to minimise the cost of implementations, as well as the cost of maintaining and implementing the system. Therefore, a flat network structure is beneficial because it lowers costs; however, there are times when it…
