Hi John,

Baseline Kubernetes hardening is necessary, but it rarely clears residual risk across the control plane, workloads, network paths, and secrets.

The Kubernetes Security Best Practices Cheat Sheet is a layer-by-layer checklist for teams that already shipped the essentials and need the next set of controls.

Inside, you’ll find:

Control plane and nodes: Tighten kubelet, API server, and NodeRestriction settings past defaults.

Workload guardrails: Ban privilege escalation, block untrusted registries, and lock mutable filesystems with concrete patterns.

Network and secrets: Cut lateral movement with network policies, mTLS/service mesh patterns, and least-privilege access.

Download the cheat sheet to close the gap between baseline hardening and production-ready cluster controls.

Thanks,

The Team at Wiz
