Assess Kubernetes cluster security posture against CIS benchmark controls using kube-bench.

Assess Kubernetes cluster security posture against CIS benchmark controls using kube-bench and produce remediation-prioritized evidence for hardening programs.

Category

Execution

6 steps, sequential + gated

Goal

Assess Kubernetes cluster security posture against CIS benchmark controls using kube-bench and produce remediation-prioritized evidence for hardening programs.

Scope

Applies to

  • +Run Kubernetes CIS benchmark
  • +Assess cluster hardening with kube-bench
  • +Generate compliance evidence for Kubernetes security controls

Does not cover

  • −Trivial changes outside the workflow domain

Triggers

"Run Kubernetes CIS benchmark""Assess cluster hardening with kube-bench""Generate compliance evidence for Kubernetes security controls""Track benchmark drift over time"

Inputs

  • →Context: environment/system affected
  • →Scope: change boundary
  • →Constraints: policy or hard rules

Invariants

  • 01Benchmark profile must match cluster platform/version context.
  • 02Results must be preserved in machine-readable format for trend analysis.
  • 03FAIL findings are prioritized before WARN findings unless justified.
  • 04Remediation recommendations must map to specific CIS control IDs.

Procedure

  1. Step 1Step 1 — **Prepare benchmark run**
  2. Step 2Step 2 — **Execute kube-bench**
  3. Step 3Step 3 — **Classify findings**
  4. Step 4Step 4 — **Prioritize remediation**
  5. Step 5Step 5 — **Validate remediations**
  6. Step 6Step 6 — **Operationalize continuous assessment**

Outputs

  • ▸kube-bench result artifacts (text/JSON/JUnit as configured).
  • ▸CIS findings summary with FAIL/WARN prioritization.
  • ▸Remediation plan mapped to control IDs.
  • ▸Re-test evidence for resolved controls.

Review Gate

  • [ ]Benchmark profile aligns with platform/version.
  • [ ]Structured report artifacts are generated and retained.
  • [ ]FAIL findings have remediation owner and plan.
  • [ ]Re-validation confirms critical fixes are effective.
  • [ ]Continuous benchmark cadence is defined.
