Container Networking Deep Dive: From Network Namespaces to Kubernetes Note: This guide is based on the Linux kernel networking documentation, Docker networking documentation (v24+), Kubernetes networking model documentation (v1.28+), and CNI specification v1.0. All examples use documented networking primitives and follow production container networking patterns. Container networking is fundamental to modern cloud-native applications. Understanding how packets flow from pod to pod, how services load-balance traffic, and how network policies enforce security requires knowledge of Linux networking primitives, Container Network Interface (CNI) plugins, and Kubernetes networking abstractions. ...

Enhancing Secure Boot with Unified Kernel Images (UKIs) ===================================================== Introduction Secure boot processes are crucial in modern computing to prevent unauthorized firmware, operating systems, or UEFI drivers from running on a computer. One of the recent developments in this area is the use of Unified Kernel Images (UKIs) to enhance boot security. In this article, we will explore the concept of UKIs and provide a step-by-step guide on how to implement them to improve secure boot processes. ...
