Kubernetes Security Review
The Kubernetes security review assesses cluster architecture, RBAC, networks, workload hardening, and supply chain risks. The outcome is a prioritized remediation plan, not just scan output.
Cluster architecture
Control plane, node pools, network design.
RBAC & workloads
Service accounts, permissions, pod security.
Prioritized fixes
Risk backlog with owners and deadlines.
A review does not replace continuous hardening. Without ownership and operational processes, findings stay open and risks reappear.
Quick overview
- Deep assessment, not an automated scan.
- Focus on RBAC, networks, workloads, and supply chain.
- Output is a prioritized remediation plan.
- clear risks per cluster and namespace
- fix priorities based on exploitability
- guardrails for CI/CD and deployments
- actionable guidance for platform teams
Fits if you …
- run Kubernetes in production.
- have multiple teams deploying workloads.
- need clarity on RBAC and pod security.
- want actionable fixes, not just findings.
Not a fit if …
- you cannot access clusters and configurations.
- you only want a shallow scan.
- no resources exist for remediation and operations.
Review vs. Kubernetes pentest vs. CSPM
deep config review for RBAC and operations.
attack-path validation and exploit evidence.
tool signals without operational fix planning.
Review for operations and guardrails, pentest for attack paths, CSPM for continuous signals.
Typical use cases
- Clusters grow without RBAC and network policy standards.
- Namespace and service account sprawl.
- Missing guardrails in CI/CD and deployments.
- Production workloads handling sensitive data.
- Audits demand proof of RBAC and isolation.
Process & methodology
Clusters, namespaces, workloads, CI/CD, logging.
RBAC, network policies, pod security, supply chain.
Fix priorities, guardrails, implementation.
Scope & preparation
- Capture cluster type, versions, and network model.
- Define namespaces, workloads, and critical services.
- Align CI/CD, image registries, and supply chain flow.
- Agree on logging and runtime monitoring.
Execution
- Review RBAC, service accounts, and secrets for least privilege.
- Validate network policies, ingress, and exposure.
- Check pod security, admission controls, and runtime policies.
- Prioritize findings into a remediation backlog.
Without ownership and CI/CD standards, risks return quickly. Guardrails must be embedded into deployments and pipelines.
Deliverables
- Prioritized findings with owners and deadlines.
- Guardrail catalog for RBAC, network policies, and pod security.
- Hardening roadmap and quick wins.
- Evidence for coverage and exceptions.
Provider selection criteria
- Experience with Kubernetes operations and CI/CD.
- Clear criteria for RBAC and network policies.
- Defensible risk prioritization.
- Access to clusters, IaC, and logs.
- Integration with ticketing and change processes.
- Measurable KPIs and reporting cadence.
Next steps
- Inventory clusters and critical workloads.
- Define RBAC, network policy, and pod security baselines.
- Prioritize and fix top risks.
- Embed guardrails in CI/CD and deployments.
