Azure Network Security: Segmenting and Isolating Cloud Workloads

In modern cloud computing, securing your network perimeter is no longer enough to protect sensitive data from sophisticated threats. To prevent unauthorized lateral movement within your infrastructure, you must design a robust, segmented network architecture. This text-based course guides you through the fundamentals of cloud network isolation. You will learn to establish a zero-trust architecture by organizing workloads into secure zones, defining precise access controls, and auditing your network security posture. What you'll learn: - Understand the core concepts of cloud network segmentation and zero-trust security architecture - Configure Network Security Groups (NSGs) and Application Security Groups (ASGs) to enforce least-privilege access - Implement centralized security policies across multiple virtual networks using Virtual Network Manager - Monitor and troubleshoot network traffic using Network Watcher diagnostic tools - Apply infrastructure-as-code principles to define and deploy consistent security rules The course begins with foundational networking and security concepts before moving into step-by-step written guides for configuring rules, managing enterprise-scale policies, and diagnosing connectivity issues. Designed for beginners in cloud security and network administration, this course requires no prior experience with cloud firewalls or advanced networking.
