Kubernetes networking
Networking on Kubernetes with Calico and eBPF
Kubernetes networking is a complex topic. There are multiple layers present — from the containers to the underlying infrastructure. Let’s dig in. Kubernetes defined the network model and the network drivers are implementations of that model. In that way, you can have multiple network drivers implem…

Kubernetes security
Hardening security on Kubernetes with KubeArmor
KubeArmor provides runtime protection on Kubernetes using policies. It uses eBPF and Linux Security Modules (LSM). It can restrict any malicious or unwanted behavior by cluster uses. As you can see the Kubearmor is placed between the kernel and running pods. In this placement, it can filter out res…
