Network Security Group

Even though February was a shorter month, there were still a number of significant Azure announcements that you should know about.

Aidan explains what you need to consider when planning for a deployment of the Azure Firewall.

Aidan shows you how to deploy application security groups to create granular (per-NIC) network security group rules in the Azure Portal.

Aidan Finn explains how the two options for associating a network security group (NSG) work, virtual machine NIC or subnet, and I’ll recommend a method to use.

Aidan Finn explains several techniques that you can use to secure and protect Azure virtual networks.

Aidan Finn describes a preview feature of Network Security Groups, called Application Security Groups, which allows you dynamically assign firewall policies to groups of Azure virtual machines.

Aidan Finn demonstrates how you can use Azure’s Network Watcher to check if one Azure virtual machine can talk to another.

Microsoft recently shared a detailed design for a secure network deployment in Azure, based on the United Kingdom’s cloud security principles. The focus of Microsoft’s article was on the UK, but we can use this design as a basis for other deployments.

In this post I will show you how to deploy and configure the Azure Resource Manager (ARM and CSP) network load balancer. The post will cover load balancing Azure virtual machines and creating NAT rules.
