Azure Firewall: Centralized Traffic Inspection and Security Rules

Securing cloud infrastructure requires robust control over network traffic, yet managing individual security groups across multiple virtual networks quickly becomes unmanageable. Azure Firewall solves this by providing centralized, cloud-native network security to inspect and filter traffic across your entire subscription. This text-only course guides you from the foundational concepts of cloud network security to deploying and managing Azure Firewall. You will learn how to structure firewall policies, enforce strict traffic filtering, and leverage threat intelligence to automatically block known malicious destinations, preparing you to design secure network architectures. What you'll learn: 1. Understand core cloud security concepts, firewall terminology, and Zero Trust network architecture. 2. Deploy Azure Firewall and configure route tables to centralize traffic flow. 3. Create and manage rule collections, including application, network, and NAT rules. 4. Implement threat-intelligence-based filtering to detect and alert on malicious traffic. 5. Integrate Azure Firewall with Virtual WAN and Secured Virtual Hubs for enterprise-scale routing. 6. Configure logging and diagnostics to monitor network traffic and analyze security events. You will begin with foundational definitions of cloud routing and network security before walking through practical, step-by-step written deployment scenarios. The material progresses logically from basic single-hub configurations to advanced multi-region architectures and threat intelligence enforcement. This course is designed for network administrators, cloud security beginners, and IT professionals looking to secure cloud infrastructure. No prior experience with Azure Firewall is required, though a basic understanding of IP addressing and virtual networks is helpful.
