One way to secure your network is by using Azure Firewall. Azure Firewall is a fully managed, cloud-based network security service that helps protect your network from threats by filtering inbound and outbound traffic. In this tutorial, we will walk you through the process of implementing Azure Firewall to secure your network.<\/p>\n<h1>Prerequisites<\/h1>\n<p>Before we start, ensure that you have the following:<\/p>\n<ul>\n<li>Basic knowledge of Azure Networking<\/li>\n<li>An Azure subscription with permissions to create resources<\/li>\n<li>A Virtual Network (VNet) with at least one subnet<\/li>\n<\/ul>\n<h1>Step 1: Create a new Azure Firewall<\/h1>\n<p>The first step in securing your network using Azure Firewall is to create a new Azure Firewall. To create a new Azure Firewall, follow these steps:<\/p>\n<ol>\n<li>Sign in to the Azure Portal with your account credentials.<\/li>\n<li>In the left-hand menu, click on \u201cCreate a resource\u201d.<\/li>\n<li>Search for \u201cAzure Firewall\u201d and click \u201cCreate\u201d.<\/li>\n<li>In the \u201cBasics\u201d tab, fill out the required fields such as Subscription, Resource Group, Firewall Name, Region, and Availability zone.<\/li>\n<li>Choose \u201cStandard\u201d as the SKU tier for added functionality.<\/li>\n<li>Click on \u201cNext: IP Configurations\u201d.<\/li>\n<\/ol>\n<h1>Step 2: Create an IP Configuration<\/h1>\n<p>The second step is to create an IP configuration for your Azure Firewall. This IP configuration is used to configure the internal IP address settings for the Azure Firewall. To create an IP configuration, follow these steps:<\/p>\n<ol>\n<li>In the \u201cIP Configurations\u201d tab, click on \u201cAdd\u201d.<\/li>\n<li>Fill out the required fields such as Name and Subnet.<\/li>\n<li>Under Public IP address settings, select \u201cCreate new\u201d.<\/li>\n<li>Fill out the required fields such as Name, SKU, and Static or Dynamic allocation.<\/li>\n<li>Click on \u201cReview + create\u201d.<\/li>\n<li>Review the details of your Azure Firewall and click on \u201cCreate\u201d to provision your new Azure Firewall.<\/li>\n<\/ol>\n<h1>Step 3: Create Firewall Rules<\/h1>\n<p>The third step is to create firewall rules to allow or deny traffic to and from your network. Firewall rules are used to define what types of traffic are allowed or blocked. To create a firewall rule, follow these steps:<\/p>\n<ol>\n<li>In the Azure Portal, navigate to the newly created Azure Firewall and click on \u201cFirewall Rules\u201d from the left-hand menu.<\/li>\n<li>Click on \u201cAdd\u201d to create a new firewall rule.<\/li>\n<li>Fill out the required fields such as Name, Priority, and Rule Type.<\/li>\n<li>Under Source, select \u201cAddress Space\u201d and enter the source IP address range that you want to allow or deny traffic to and from. You can also select \u201cVirtual Network\u201d or \u201cIP Group\u201d depending on your need.<\/li>\n<li>Under Destination, select \u201cAddress Space\u201d and enter the destination IP address range that you want to allow or deny traffic to and from. You can also select \u201cVirtual Network\u201d or \u201cIP Group\u201d depending on your need.<\/li>\n<li>Under Protocol, select the protocol that you want to allow or deny traffic for such as TCP, UDP, or Any.<\/li>\n<li>Under Action, select \u201cAllow\u201d or \u201cDeny\u201d depending on what you want to do with the traffic.<\/li>\n<li>Specify the rule name and description.<\/li>\n<li>Click on \u201cReview + create\u201d.<\/li>\n<li>Review the details of your firewall rule and click on \u201cCreate\u201d to create your new firewall rule.<\/li>\n<\/ol>\n<p>You can create multiple firewall rules to suit your organization&#8217;s needs.<\/p>\n<h1>Step 4: Configure Network Rules<\/h1>\n<p>The fourth step is to configure network rules to allow or block traffic to and from your network. Network rules are used to define what types of traffic are allowed or blocked between specific IP addresses. To create a network rule, follow these steps:<\/p>\n<ol>\n<li>In the Azure Portal, navigate to the newly created Azure Firewall and click on \u201cNetwork Rules\u201d from the left-hand menu.<\/li>\n<li>Click on \u201cAdd\u201d to create a new network rule.<\/li>\n<li>Fill out the required fields such as Name, Priority, and Rule Type.<\/li>\n<li>Under Source, select \u201cIP Addresses\u201d and enter the IP address that you want to allow or deny traffic to or from. You can also select \u201cVirtual Network\u201d or \u201cService Tag\u201d depending on your need.<\/li>\n<li>Under Destination, select \u201cIP Addresses\u201d and enter the IP address that you want to allow or deny traffic to or from. You can also select \u201cVirtual Network\u201d or \u201cService Tag\u201d depending on your need.<\/li>\n<li>Under Protocol, select the protocol that you want to allow or deny traffic for such as TCP, UDP, or Any.<\/li>\n<li>Under Action, select \u201cAllow\u201d or \u201cDeny\u201d depending on what you want to do with the traffic.<\/li>\n<li>Specify the rule name and description.<\/li>\n<li>Click on \u201cReview + create\u201d.<\/li>\n<li>Review the details of your network rule and click on \u201cCreate\u201d to create your new network rule.<\/li>\n<\/ol>\n<p>You can create multiple network rules to suit your organization&#8217;s needs.<\/p>\n<h1>Step 5: Associate Firewall with VNet and Subnet<\/h1>\n<p>Now that you have created your Azure Firewall, firewall rules, and network rules, the next step is to associate your Azure Firewall with your Virtual Network and Subnet. To do this, follow these steps:<\/p>\n<ol>\n<li>In the Azure Portal, navigate to the newly created Azure Firewall and click on \u201cFirewall Manager\u201d from the left-hand menu.<\/li>\n<li>Click on \u201cVirtual networks\u201d and click on \u201cConnect\u201d.<\/li>\n<li>Select the Virtual Network that you want to associate with your Azure Firewall.<\/li>\n<li>Select the Subnet that you want to associate with your Azure Firewall.<\/li>\n<li>Click on \u201cAssociate\u201d to connect your Azure Firewall to your Virtual Network and Subnet.<\/li>\n<\/ol>\n<h1>Step 6: Test your Firewall<\/h1>\n<p>The final step is to test your Azure Firewall to ensure that it is working correctly. To test your Azure Firewall, follow these steps:<\/p>\n<ol>\n<li>In the Azure Portal, navigate to the newly created Azure Firewall and click on \u201cPublic IP addresses\u201d from the left-hand menu.<\/li>\n<li>Note down the Public IP address of your Azure Firewall.<\/li>\n<li>SSH or RDP into a VM in your Virtual Network.<\/li>\n<li>Open a web browser and navigate to a website. You should not be able to access the website.<\/li>\n<li>Create a firewall rule to allow outbound traffic on port 80 for your VM to the Internet.<\/li>\n<li>Refresh the website on your web browser. You should now be able to access the website.<\/li>\n<\/ol>\n<p>Congratulations! You have successfully implemented Azure Firewall to secure your network.<\/p>\n<h1>Conclusion<\/h1>\n<p>Azure Firewall is a powerful tool that provides network security to your organization. By following the steps outlined in this tutorial, you can implement Azure Firewall to enhance your organization&#8217;s network security posture. Remember to review your firewall and network rules regularly to ensure they are updated and providing the best protection.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Introduction In today\u2019s dynamic threat environment, security is a primary concern for organizations.
