Azure Web Application Firewall: Implement Firewall in Front Door
Hi buddies..! this is my nineth article on Microsoft Azure Services series. In this article i will Implement Front Door Firewall using Azure WAF policies. If you missed my previous article Azure Front Door? you can check the below link.
What is Firewall?
A firewall is a network security device that monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules. Its purpose is to establish a barrier between your internal network and incoming traffic from external sources (such as the internet) in order to block malicious traffic like viruses and hackers.
Azure Firewall is a managed, cloud-based network security service that protects your Azure Virtual Network resources..Azure Web application firewall allows us to define firewall policies and deploy it in Front Doors or in Application Gateways.
Let’s see how to setup firewall in Azure Front Door. In one of my previous article i had done How to consume Azure Front Door, their i skipped the firewall setup. do it here..!
- We need create Web Application Firewall Policy to configure firewall. So Search Web Application Firewall Policy click and Add policy.
In the policy for Field select Global WAF(Front Door).
You can setup other settings too but i will skip it and Review and create.
2. Next we need to enable FrontDoor Firewall and this policy we created.
Go to created Frond Door → Click Web Application firewall → select the Frontend you need to add and add the WAF policy and save .
Boom..! we had done firewall in Front Door. We can also implement firewall in application gateways using WAF policy.
See you in next article.
Thank you..! Have a nice day.
