Kubernetes Security Specialist (CKS)
Kubernetes is a Cloud Orchestration Platform providing reliability, replication, and stability while maximizing resource utilization for applications and services. Our Securing Kubernetes course emphasizes the skills and knowledge for securing container-based applications and Kubernetes platforms, during build, deployment, and runtime. As a security expert in the DevOps world, your role is to observe and track activity. This means you need to understand processes without inserting secure systems or gatekeepers into the process and slowing it down. You must be able to observe rapidly progressing DevOps processes and pinpoint which container, process, or subsystem causes a security concern.
