At Bion, we help secure your Kubernetes clusters across all stages: build, deployment, and runtime. Our expertise safeguards your applications against known vulnerabilities and emerging threats.

With increasing adoption of Kubernetes and containerised applications, organisations face new risks that require advanced security measures: - **Increased Complexity:** Containerised applications create intricate architectures, making security more challenging. - **Multiple Attack Vectors:** Each Kubernetes component, from infrastructure to applications, introduces specific risks that must be mitigated. ![kubernetes_security_critical](https://www.bionconsulting.com/hubfs/kubernetes_security_critical.webp) ## What We Secure in Kubernetes Environments We focus on securing the core layers of Kubernetes platforms — from cluster configuration and access control to workload, network, and runtime security — using practical, production-ready controls. - **Cluster & Control Plane Security** Hardening cluster configurations, API server access controls, and admission policies. - **RBAC & Identity Management** Reviewing and tightening role-based access control, service accounts, and permissions. - **Network Security & Policies** Implementing Kubernetes NetworkPolicies to control pod-to-pod and namespace traffic. - **Workload & Pod Security** Securing pod configurations, security contexts, and runtime behaviour. - **Image & Supply Chain Security** Scanning container images and validating artifacts before deployment. - **Secrets & Configuration Security** Secure handling of secrets and sensitive configuration data. ##### Kubernetes Security & Compliance Alignment We align Kubernetes environments with recognised security benchmarks and standards such as the CIS Kubernetes Benchmark and cloud provider best practices, focusing on configuration hardening, access control, and auditability. ##### Kubernetes Security on AWS (EKS) We apply Kubernetes security best practices across Amazon EKS environments, covering cluster access controls, network segmentation, workload security, and integration with AWS-native security services. ## Key Security Challenges in Kubernetes According to the fall 2020 edition of the "State of Container and Kubernetes Security" report, **90%** of survey respondents had experienced a **security incident** in their container and Kubernetes environments over the last 12 months.   #### Infrastructure Security Vulnerabilities at the infrastructure layer put the entire system at risk. #### Cluster Security API server and kubelet vulnerabilities can lead to unauthorised access and disruption. #### Container Security Insecure images and privileged users expose applications to attacks. #### Application Security Vulnerable dependencies, exposed ports, and lack of security in the application pipeline increase the risk of breaches. ## Common Kubernetes Attack Vectors Kubernetes environments are prone to several attack vectors, which include: - **Infrastructure Compromise:** Weaknesses in the underlying infrastructure can lead to breaches. - **API Server Exploits:** Exploiting vulnerabilities in the Kubernetes API server. - **Container Image Vulnerabilities:** Insecure images may contain hidden vulnerabilities. - **Application Dependencies Exposure:** Unprotected dependencies expose the application to risks. ![common_kubernetes_attack_vectors](https://www.bionconsulting.com/hubfs/common_kubernetes_attack_vectors.webp) ## How We Can Help Kubernetes provides built-in security features, but relying solely on these defaults or misconfigurations can expose your environment to serious threats. While the platform has protections in place, attackers can exploit vulnerabilities. Bion’s Kubernetes-certified engineers offer end-to-end security for your Kubernetes clusters, ensuring that best practices are followed throughout the build, deployment, and runtime phases. Our proactive approach addresses risks at every stage, from securing the infrastructure to protecting running workloads. Our Kubernetes security services are delivered as assessments, hardening initiatives, and ongoing security support depending on your platform maturity and operational needs. ![021-cyber security](https://www.bionconsulting.com/hubfs/icons/021-cyber%20security.png) ### Cluster Hardening Ensuring that your Kubernetes clusters are configured securely from the ground up. We apply best practices to limit exposure, secure configurations, and reduce the attack surface. ![001-cyber security](https://www.bionconsulting.com/hubfs/icons/001-cyber%20security.png) ### Workload Security Bion secures your containerised workloads by enforcing strict security policies, scanning for vulnerabilities, and implementing runtime protection to prevent breaches in real time. ![010-monitor](https://www.bionconsulting.com/hubfs/icons/010-monitor.png) ### Continuous Monitoring We provide real-time observability and continuous monitoring of your Kubernetes environments, allowing for rapid detection of security issues and immediate response to potential threats. ## Kubernetes Security Practices Used Our comprehensive Kubernetes security practices ensure your clusters are resilient and protected from a range of threats. We focus on hardening the infrastructure by applying advanced policies, such as Role-Based Access Control (RBAC) and privileged user restrictions. Additionally, we secure your workloads through proper application secrets management, image vulnerability scanning, and enforcing network and pod security policies. From CI/CD security to runtime container protection, we ensure compliance with industry standards like CIS benchmarking, providing full observability and secure ingress for your environment. - Cluster hardening - Design and implement RBAC - Disallow privileged users - Application secrets management - Secure CI/CD - Image vulnerability scanning - Network policies - Pod security policies - Secure Ingress - CIS benchmark - Observability - Runtime container security ### Secure Your Kubernetes Environment with Confidence At Bion, we offer a [**Kubernetes security audit**](https://www.bionconsulting.com/kubernetes-security-audit?hsLang=en) to assess the security posture of your cluster and applications. Our tailored report provides actionable recommendations to enhance your Kubernetes security. From infrastructure hardening to securing CI/CD pipelines, our team of certified engineers delivers comprehensive solutions that ensure end-to-end security. Focus on innovation while we manage the risks. Schedule your **consultation** today and let Bion safeguard your Kubernetes environment, keeping your workloads secure with continuous monitoring and expert support. ![bion-logo-white-122x40](https://www.bionconsulting.com/hubfs/bion-logo-white-122x40.png) Bion Consulting helps organisations build secure, scalable, and high-performing cloud environments.
