Kubernetes Network Policies
Docker & Kubernetes Security
Simple
Kubernetes Network Policies is a building block of "Docker & Kubernetes Security". In plain terms: image scanning, k8s rbac, network policies, runtime detection, admission control. This topic focuses specifically on kubernetes network policies and the core ideas you need to understand it.
Technical
Technically, Kubernetes Network Policies involves the mechanisms, data structures and protocols that underpin docker & kubernetes security. You will study how it is implemented, how it is configured, how it fails, and how its behavior shows up in logs, traffic or code.
Why it matters
Containers are the default deployment unit; misconfigurations are epidemic.
Example
In a real organization, professionals working in cloud-native security, platform, devsecops. rely on kubernetes network policies to make decisions — for example, explaining an alert, hardening a system, or writing a finding in a report.
Practice idea
Build a small lab in a VM and experiment with kubernetes network policies using the related tools below. Document what you observe.
Deep dive
Read the official documentation and relevant RFCs/standards for Kubernetes Network Policies. Explore edge cases, internals, and how attackers and defenders view it differently.
