Kubernetes Security
Security hardening, policy enforcement, and runtime protection for container orchestration environments.
Definition
What is Kubernetes Security?
Kubernetes Security encompasses the practices, tools, and configurations required to protect containerized workloads running on Kubernetes clusters. It spans multiple layers: cluster hardening (API server security, RBAC configuration, node security), workload security (pod security standards, container image scanning, admission controllers), network security (network policies, service mesh encryption), secrets management (vault integration, encrypted secrets), runtime security (behavioral anomaly detection for container processes), and supply chain security (image provenance, SBOM generation).
Why It Matters
Kubernetes has become the dominant platform for production workloads — and a major attack surface. Misconfigured RBAC, privileged containers, insecure defaults, and exposed dashboards have led to numerous high-profile breaches. The CNCF reports that 96% of organizations use or are evaluating Kubernetes, but Kubernetes-specific security expertise is scarce. A default Kubernetes installation is not production-secure and requires deliberate hardening.
How It Works
Kubernetes security hardening follows the CIS Kubernetes Benchmark, implements Pod Security Standards (Restricted or Baseline profiles), configures RBAC with minimum necessary permissions, deploys admission controllers (OPA Gatekeeper, Kyverno) for policy enforcement, integrates container image scanning into CI/CD (Trivy, Grype), and implements runtime security tools (Falco, Tetragon) for behavioral monitoring.
Our Approach
Paxanimi's Approach to Kubernetes Security
Paxanimi implements Kubernetes security hardening and ongoing security management for production clusters. We conduct Kubernetes security assessments using the CIS Benchmark, implement admission control policies, configure network policies for microsegmentation, and deploy runtime security tools. For organizations building on managed Kubernetes (EKS, AKS, GKE), we implement cloud-specific security controls including node group hardening and integrated IAM.
