vamp-k8s-audit 3.2.0

# vamp-k8s-audit

Kubernetes Security Auditor — part of the VampSecure Labs toolkit.

🇬🇧 English · 🇪🇸 Español

---

🇬🇧 English

Kubernetes Security Auditor — detects dangerous configurations in Kubernetes clusters through kubectl queries (no SDK required). Produces structured findings with remediation guidance, JSON output, and a professional HTML report for client delivery.

---

Prerequisites

• Python 3.8+
• kubectl installed and reachable in PATH
• Active cluster access — the current kubectl context must point to the target cluster
• Sufficient RBAC permissions to read: pods, services, secrets, configmaps, clusterrolebindings, rolebindings, networkpolicies, ingresses, namespaces, nodes

Optional, for PDF export:

pip install fpdf2>=2.7

---

Installation

pip install vamp-k8s-audit
# or with Homebrew:
brew install vampsecure-labs/labs/vamp-k8s-audit

git clone <repo-url> vamp-k8s-audit
cd vamp-k8s-audit
pip install -r requirements.txt   # optional, only needed for PDF

No additional dependencies beyond Python stdlib are required for JSON and HTML output.

---

Usage

# Basic audit — current kubectl context, all namespaces
python3 vamp_k8s_audit.py

# Specific context and namespace
python3 vamp_k8s_audit.py --context prod-cluster --namespace production

# Save findings as JSON
python3 vamp_k8s_audit.py --output findings.json

Audit Phases and Finding IDs

Phase	Scope	Finding IDs	Key Checks
1 — Cluster Context	Cluster-wide	K8S-001..K8S-009	Anonymous API access, node versions, node health
2 — RBAC	Cluster + namespaces	K8S-010..K8S-029	cluster-admin SA bindings, wildcard ClusterRoles, default SA permissions, anonymous user permissions
3 — Pod Security	All pods	K8S-030..K8S-059	Privileged containers, root execution, privilege escalation, dangerous capabilities, hostPID/IPC/Network, sensitive host mounts, missing resource limits
4 — Network	All namespaces	K8S-060..K8S-079	LoadBalancer/NodePort exposure, missing NetworkPolicies, Ingress without TLS, Dashboard exposure, etcd TCP access
5 — Secrets	All namespaces	K8S-080..K8S-099	Secrets in plain env vars, secrets in ConfigMaps, Opaque secrets in default namespace
6 — Images & Runtime	All pods	K8S-090..K8S-109	:latest tags, public registries, missing readOnlyRootFilesystem, missing Pod Security Admission
10 — Control Plane CIS (--audit-control-plane)	Node manifest files	K8S-ETCD-/K8S-KCM-/K8S-KSCHED-*	CIS benchmark checks for etcd (8), kube-controller-manager (8), kube-scheduler (3), kubelet anonymous auth (1)

Finding Severity Distribution

Severity	Color	Meaning
CRITICAL	Red	Immediate exploitation risk, full cluster compromise
HIGH	Orange	Significant security weakness requiring urgent attention
MEDIUM	Yellow	Configuration issue reducing security posture
LOW	Blue	Best practice deviation
INFO	Grey	Informational observation

---

Exit Codes

Code	Meaning
0	No CRITICAL or HIGH findings
1	At least one HIGH finding detected
2	At least one CRITICAL finding detected

These codes are suitable for use in CI/CD pipelines to gate deployments.

---

Output Formats

Console — Color-coded ANSI output with severity badges, affected resources, and a summary table.

JSON (--output FILE) — Structured VSL schema with metadata, summary by severity, and full finding detail.

HTML (--report-html FILE) — Standalone professional report for client delivery. Includes cover page, executive summary with risk bars, findings table, and detailed cards. No external dependencies (fully self-contained).

---

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: vamp-k8s-audit-reader
rules:
- apiGroups: [""]
  resources:

Why vamp-k8s-audit vs. kube-bench · Kubescape · Trivy (k8s mode)

Feature	vamp-k8s-audit	kube-bench	Kubescape	Trivy k8s
RBAC misconfiguration analysis	✅	❌	✅	⚠️ partial
Pod Security context checks	✅	✅	✅	✅
Secrets in env vars / ConfigMaps	✅	❌	⚠️ partial	❌
YAML-extensible rules engine	✅	❌	❌	❌
--delta FILE diff between two scans	✅	❌	❌	❌
kube-bench wrapper integration	✅	N/A	❌	❌
CI/CD exit codes (0 / 1 / 2)	✅	❌	✅	✅
Client-ready HTML + PDF engagement report	✅	❌	❌	❌
No SDK — pure kubectl queries	✅	✅	❌	❌

• kube-bench specializes in CIS benchmark checks at the node/control-plane level (SSH/manifest-based) and excels at that scope; it does not analyze RBAC bindings, runtime pod configurations, or secret exposure in workloads.
• Kubescape is a broad compliance scanner with a large framework library, but requires deploying an in-cluster agent for full coverage; vamp-k8s-audit needs only kubectl read permissions.
• Trivy (k8s mode) focuses on image vulnerability scanning and misconfiguration detection, but its findings are not structured for client-delivery reporting and it has no --delta comparison mode.
• vamp-k8s-audit is the only tool in this comparison with an extensible YAML rules engine (add checks as data without modifying Python) and a built-in --delta FILE mode to track security posture changes between consecutive audits.

Legal Notice

This tool is intended for authorized security audits only. Using it against clusters you do not have explicit permission to test is illegal and unethical.

Phase 10 — Control Plane CIS (--audit-control-plane)

Inspects control plane component manifest files (/etc/kubernetes/manifests/) on the cluster nodes to verify CIS Kubernetes Benchmark compliance. Requires SSH access or a tool that can read node manifests.

Version History

Version	Main changes
v3.2.0	Fixed the file-report path (--output/--format): it called meta_from_args with the wrong arity and non-existent save_* methods, so it never produced a file. Added the standard VSL client-report flags (--client/--engagement/--auditor/--report-scope/--report-html/--report-pdf); --format now json/html/pdf (dropped the unimplemented markdown). README CLI table reconciled with the real flags.
v3.1.1	Bilingual README (EN/ES)
v3.1.0	+14 YAML checks · cis_admission_audit.yaml: ValidatingWebhook/MutatingWebhook failurePolicy:Ignore (HIGH), webhook sideEffects:Some/Unknown (MEDIUM), Pod seccompProfile absent (MEDIUM CIS 5.7.2), runAsUser:0 in containers+initContainers (HIGH CIS 5.2.6), capabilities.add (HIGH CIS 5.2.9), PodSecurityPolicy privileged:true (HIGH CIS 5.2.1), PV/SC reclaimPolicy:Delete (MEDIUM), SC without allowVolumeExpansion (LOW), namespace without ResourceQuota/LimitRange (MEDIUM/LOW) · 58 total checks · 4 YAML files
v3.0.0	Extensible YAML engine — 3 rules/*.yaml files, 44 CIS checks; kube-bench wrapper (--kube-bench); 15 cmd_flag_* operators; --delta FILE diff mode; importable package
v2.2.0	Phase 11 — node and kubelet checks via process flags; cmd_flag_ge/le/regex operators; 27 tests
v2.1.0	Phase 10 delta scan (--delta FILE) and YAML engine beta (network/RBAC checks as data)
v2.0.0	Phase 10 control plane CIS — --audit-control-plane, 20 new etcd/KCM/scheduler/kubelet checks
v1.3	Phases 1-6, Phase 6 images, HTML report
v1.0	MVP RBAC + Pod Security + Network + Secrets
