Kubernetes security refers to the practices, controls, and tools used to protect Kubernetes clusters, workloads, and data from threats and misconfigurations. It spans access control, network security, workload isolation, and supply chain protection. Also known as K8s security, it is critical for running Kubernetes safely in production.
Kubernetes introduces new attack surfaces due to its dynamic and distributed nature. Misconfigurations, overly permissive access, and insecure images can lead to breaches. Strong Kubernetes security reduces risk, protects sensitive data, and ensures compliance with organisational and regulatory requirements.
Kubernetes security is enforced through policies and controls such as RBAC for access management, network policies for traffic isolation, image scanning for vulnerabilities, and runtime monitoring for suspicious behavior. Continuous validation and observability help detect and respond to threats in real time.
BuildPiper embeds Kubernetes security into its DevSecOps platform by enforcing approvals, policies, and security checks across CI/CD, environments, and deployments. It provides visibility into security posture and integrates security into the release process without slowing teams down.
Kubernetes provides security primitives, but it is not secure by default. Proper configuration, policies, and operational practices are required to run it securely in production.
Common risks include misconfigured RBAC, exposed APIs, insecure container images, lack of network segmentation, and insufficient monitoring.
BuildPiper supports Kubernetes security by integrating access control, policy enforcement, and security checks into delivery workflows, enabling teams to manage risk proactively while maintaining velocity.
