Azure Network Security Groups (NSG) Step-by-Step Tutorial

In this video, we will explore how to use Azure network security groups (NSGs) to control traffic in your virtual networks. NSGs act as a firewall for your Azure resources, allowing you to filter traffic between subnets and define inbound and outbound rules. We'll cover some key topics: What are network security groups and how do they work in Azure? How to create and configure a network security group using the Azure portal and ARM templates Setting up security rules, defining source, destination, ports, and protocols Using service tags, application security groups, and network virtual appliances with NSGs Viewing effective security rules and troubleshooting NSGs Best practices for implementing NSGs as part of your overall network security architecture NSGs are a fundamental component of securing resources like virtual machines, web apps, databases and more in Azure. By the end of this video, you'll understand how to leverage NSGs to control traffic flows and enhance security through segmentation and micro-perimeterization.
