Providing security for our infrastructure and applications is a never-ending continuous process. This article will talk about security in Kubernetes clusters, traffic incoming and outgoing to/from the cluster, and the traffic within the cluster. Some organizations behave as if their own workloads can be malicious and design their security policies accordingly. In addition, in today’s world, we all use third-party plugins, libraries, and pieces of code from external resources. Although this has been increasing productivity, this also brings many security concerns. Isolating the traffic incoming and outgoing to our applications to only what’s absolutely necessary is one of the best approaches there is.
