Building Secure Kubernetes Platforms

Kubernetes Security

Kubernetes security requires hardened nodes, pod security standards, network policies, image signing, and runtime detection working together in a coherent security architecture.

Security Layers

1. Node hardening: Immutable OS, minimal attack surface

2. Pod security: Pod Security Standards (PSS), Pod Security Admission (PSA)

3. Network policies: Micro-segmentation, zero-trust networking

4. Image security: Signed images, vulnerability scanning

5. Runtime detection: Falco, tracee for behavioral monitoring
