![]() ![]() This approach helps ensure that the guidelines and recommendations are comprehensive, relevant, and effective in protecting against cyber threats. The guidelines are based on a combination of industry standards and best practices, real-world threat intelligence, threat modeling, risk management, and compliance requirements. These include auditors, security practitioners, legal experts, software developers, federal agencies, etc. Based on Collective Knowledge and ExpertiseĬIS recommendations are developed through a consensus review process by bringing together experts from a diverse set of backgrounds. These guidelines are simple and straightforward to implement, allowing cluster administrators to perform security audits without requiring extensive investment in resource upskilling or tool licenses. The benchmark is written for rapid security assessment of all layers of a Kubernetes ecosystem. Apart from offering recommended practices, CIS guidelines also offer up-to-date, practical steps that stay relevant across all stages of a cluster lifecycle. Updated Guidance on Container SecurityĬIS Benchmarks are frequently updated to address emerging vulnerabilities and exploits. While in-house adoption of CIS-recommended practices is a common approach, major cloud providers also offer CIS-hardened images for secure, scalable, and on-demand computing environments out of the box. It provides actionable insights on cluster vulnerabilities, common attack patterns, and remediation options. The benchmark is a comprehensive set of guidelines that encompass all components of the Kubernetes ecosystem. There are several merits to using the CIS Kubernetes Benchmark for security hardening. Benefits of Leveraging CIS Benchmark for Kubernetes Security Suggested practices include using stable images, adopting secure coding practices, securing the container registry, and all other techniques that ensure Kubernetes deployment objects only run safe workloads. Workload-level security recommendations cover hardening practices for containers, code, and other applications running on the data plane. Although the recommended standards are mostly similar for both the control plane and worker nodes, organizations should consider additional security controls for control plane hosts, as a breach may potentially result in a cluster-wide compromise. Node-level recommendations consist of various configuration guidelines to secure nodes at the operating system level. Kubernetes nodes are physical or virtual machines used to host containerized workloads in Kubernetes clusters. Whether clusters are built on-premises or in the cloud, the CIS Benchmark offers recommended practices to detect cluster vulnerabilities while helping define secure network access policies for cluster resources. Cluster-Level SecurityĬluster-level security recommendations encompass the physical infrastructure, configurable components, and services that are part of cluster operations. There are three levels of security for CIS Kubernetes policies. Levels of Security for CIS Policies in KubernetesĬIS recommendations are typically categorized according to the layer of the Kubernetes stack to which they are applied. Unlike other frameworks, the CIS Benchmark offers detailed, well-defined, consensus-driven recommendations for securely creating configuration files, avoiding misconfigurations of the control plane, and adopting security policies for hardening containerized workloads. The CIS Kubernetes Benchmark puts forward recommended procedures to set up Kubernetes clusters and workloads with the aim of adopting a strong security posture. What Is the CIS Benchmark for Kubernetes? In this article, we will discuss the CIS Benchmark for Kubernetes, its recommended hardening policies, and popular tools that scan an existing cluster to validate against the CIS Benchmark. The Center for Internet Security (CIS) is a non-profit organization that offers tested and proven best practices to help organizations protect their systems and networks from security threats.ĬIS Benchmarks are a set of best practice security configuration guidelines for various technology platforms and software. Security frameworks help modern software organizations define their risk management processes and platform requirements to prevent cyber threats. In this article, we compare the leading tools that scan against the CIS Kubernetes benchmark framework. ![]() CIS Benchmarks are a focused set of guidelines for the secure configuration, vulnerability detection, and threat remediation of distributed workloads. ![]()
