As organizations increasingly migrate applications, workloads, and data to the cloud, securing cloud networks has become a critical priority. Traditional network security approaches are no longer sufficient in highly dynamic cloud environments where users, applications, and services communicate across multiple platforms and geographic locations. The Cloud Network Security And Segmentation Basics course provides a comprehensive introduction to cloud networking security principles, secure infrastructure design, segmentation strategies, threat detection, and governance practices. Learners will develop a practical understanding of how cloud networks are structured, how security controls are applied, and how segmentation helps reduce the impact of cyberattacks. The course explores key concepts including Virtual Private Clouds (VPCs), security groups, network access controls, VPNs, microsegmentation, intrusion detection systems, security monitoring, and Zero Trust networking. Participants will also learn how modern organizations protect cloud workloads, manage risk, and maintain secure communications across hybrid and multi-cloud environments. Whether you are beginning a career in cloud security or seeking to strengthen your understanding of cloud networking fundamentals, this course provides the knowledge needed to support secure cloud operations and modern security architectures.
