Kubernetes Security Training in Kuala Lumpur, Malaysia

This intensive instructor-led course provides participants with a practical and hands-on understanding of securing Kubernetes clusters, workloads, and cloud environments. The program focuses on real-world attack scenarios, defense strategies, and the application of Kubernetes-native security features.

Participants learn how attackers compromise Kubernetes, how to design and enforce security controls, and how to use open-source tools and built-in Kubernetes capabilities to protect clusters. Through demonstrations and optional labs, learners will gain the confidence to secure production-grade Kubernetes environments end to end.
