Summary
In this chapter, we discussed what NSGs are and how to use them to create new rules, as well as how to associate them with a subnet. We also discussed how to evaluate NSG rules based on priority. Lastly, we covered Azure Firewall and Azure Bastion, what they do, and how to configure them via a hands-on demo.
After reading this chapter, you should now know how to secure VNets via an NSG and secure resources by using Azure Bastion and Azure Firewall. In the next chapter, we'll cover how to configure load balancing by using Azure Application Gateway and internal and external load balancers, and how to troubleshoot load balancing.
