Cluster Hardening

1. Control Plane Security
```
# Audit policy
apiVersion: audit.k8s.io/v1
kind: Policy
rules:
  - level: Metadata
    resources:
      - group: ""
        resources: ["secrets", "configmaps"]
  - level: RequestResponse
    resources:
      - group: ""
        resources: ["pods/exec", "pods/portforward"]
```
2. Network Policies
```
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: default-deny
spec:
  podSelector: {}
  policyTypes:
    - Ingress
    - Egress
```
Runtime Security
- Falco – Runtime threat detection
- Tracee – eBPF-based runtime security
- KubeArmor – Cloud-native runtime enforcement
Supply Chain Security
- Sigstore/Cosign – Container signing
- SBOM – Software Bill of Materials with Syft
- Admission Controllers – Kyverno, OPA Gatekeeper
