Configuring Network Security Groups in Azure Virtual Networks

Cloud security starts at the network level, but configuring traffic rules incorrectly can leave your assets exposed or block critical services. This course provides a clear, step-by-step approach to managing network traffic flow and securing cloud resources using Azure Network Security Groups (NSGs). You will transition from understanding basic networking concepts to confidently implementing robust security rules that protect your virtual machines and subnets. By learning how to control inbound and outbound traffic, you will establish a solid foundation for modern cloud security administration. What you'll learn: Learn the core components of Azure virtual networking and security architecture; Configure Network Security Group rules to filter inbound and outbound traffic effectively; Apply zero-trust security concepts by implementing the principle of least privilege; Associate security groups with subnets and individual network interfaces; Prioritize security rules correctly to prevent common configuration conflicts; Troubleshoot connectivity issues using security diagnostics and flow logs. This text-based course guides you through foundational networking definitions before moving into practical rule configuration patterns and security best practices. It is designed for beginners, system administrators, and aspiring cloud security professionals with no prior Azure experience required.
