Kubernetes & Container Security Audits
In-depth security reviews for K8s clusters, RBAC authorization matrices, Helm charts, and container pod isolation controls.
Kubernetes Cluster Security Audit Modules
1. K8s RBAC Permission Matrix Audit
Identifying over-privileged ServiceAccounts, ClusterRoles, and RoleBindings that could allow container breakouts, API credential scraping, or full cluster takeover.
2. Pod Security & Image CVE Scanning
Evaluating Pod Security Admission (PSA) policies to prevent containers from running as privileged root, mounting host directories, or bypassing Linux seccomp/AppArmor profiles.
3. Network Policies & Egress Isolation
Auditing CNI network policies (Calico, Cilium) to enforce strict zero-trust pod-to-pod segmentation and prevent unauthorized lateral movement and metadata server access.
4. Secret Management & Control Plane Hardening
Reviewing etcd encryption at rest, API server TLS configurations, admission controllers, and integrating external vaults (AWS Secrets Manager, HashiCorp Vault) via CSI drivers.
Kubernetes Hardening & Compliance Deliverables
Our certified Kubernetes practitioners assess your EKS, GKE, AKS, or bare-metal clusters against CIS Kubernetes Benchmarks. We provide ready-to-apply YAML manifests, Helm values overrides, and network policy definitions to remediate security gaps without causing application downtime.
Frequently Asked Kubernetes Security Questions
How do you audit Kubernetes clusters without impacting production workloads?
We utilize read-only audit roles, offline manifest inspection, and passive configuration scanning against live control planes. Simulated attack scenarios and breakout vectors are executed exclusively in dedicated staging environments or using calibrated, non-destructive payloads.
Do you assess managed cloud services like AWS EKS, GCP GKE, and Azure AKS?
Yes. In addition to core Kubernetes objects, we assess cloud IAM role-binding mappings (AWS IRSA, GCP Workload Identity, Azure Workload Identity), managed node group hardening, private endpoint configurations, and control plane audit logging.
Which compliance and security standards are referenced during the audit?
We benchmark your cluster configurations against CIS Kubernetes Benchmark v1.8+, NSA/CISA Kubernetes Hardening Guidance, MITRE ATT&CK for Containers, and relevant SOC 2 / ISO 27001 technical control requirements.
What remediations are delivered for detected cluster vulnerabilities?
Every vulnerability report includes reproducible proof-of-concept steps, severity scoring via CVSS v3.1, ready-to-merge Kubernetes NetworkPolicy manifests, RBAC least-privilege role definitions, and 30 days of re-testing support.
