Purpose

Section titled “Purpose”

This runbook provides a repeatable methodology for performing professional Kubernetes penetration testing engagements.

Rather than focusing on isolated vulnerabilities, this methodology guides consultants through a structured assessment covering architecture, identity, workloads, networking, runtime security, governance, attack path analysis, and executive reporting.

The objective is to evaluate the organization’s overall Kubernetes security posture while producing consulting-quality deliverables for both technical and executive stakeholders.

Engagement Objectives

Section titled “Engagement Objectives”

The assessment aims to:

  • Understand the Kubernetes architecture.
  • Identify security weaknesses.
  • Evaluate Kubernetes hardening.
  • Review identity and RBAC.
  • Assess workload security.
  • Review network segmentation.
  • Assess runtime protection.
  • Identify attack paths.
  • Evaluate business risk.
  • Deliver actionable remediation guidance.
