Securing Kubernetes clusters is a critical task for ensuring robust cloud-native application performance and safeguarding sensitive data. Still, security is a multidisciplinary domain that interferes with storage, networks, hardware, applications, etc. This session offers practical, hands-on guidance for implementing advanced security measures around Kubernetes. Drawing from real-world scenarios and demos, we will cover key strategies including Zero Trust principles for kubectl access, effective role-based access control (RBAC), and safeguarding secrets through mechanisms like Etcd encryption and the CSI Secrets Store Driver.
Attendees will gain actionable insights into addressing multi-tenant traffic isolation challenges, managing user identities with the least privilege, and integrating vault for external secrets. The presentation also explores network security enhancements for hub-spoke architectures and container image security using passwordless pulls from private registries.
