Azure Security Center Integration
Forward firewall logs to the Azure Security Center dashboard
for a consolidated view on the security of your Azure deployment.
Use this view to assess and prioritize security alerts across your
Azure subscription.
Microsoft has deprecated Azure Security Center support
for partner security solutions and replaced it with Azure Sentinel.
The VM-Series firewall is integrated with Azure Security Center
to provide a unified view for monitoring and alerting on the security
posture of your Azure workloads. On Azure Security Center, the VM-Series
firewall is available as a partner security solution that protects
your Azure workloads from threats and mitigates any gaps in securing
your business and intellectual property in the public cloud. To
enable this integration and display logs as security alerts directly
on the Azure Security Center dashboard, the VM-Series firewall on
Azure includes a Log Forwarding profile.
To get started, you need to enable Azure Security Center on your
Azure subscription. You then have two ways in which you can enable
this integration:
- Deploy the VM-Series firewall based on a recommendation on the Azure Security Center dashboard.

When the Azure Security Center dashboard recommends that you deploy a VM-Series firewall to secure a workload that is exposed to the internet, you can only deploy the firewall in an new resource group or an existing resource group that is empty. This is because Azure currently restricts you from deploying a multi NIC appliance in an existing resource group. Therefore, after you deploy the VM-Series firewall you must manually configure it to be in the path of traffic of the workload that you need to secure.When you deploy the firewall from Azure Security Center, the firewall is launched with three network interfaces—management, external facing (untrust) and internal facing (trust)—and a user defined route (UDR) that sends all outbound traffic from the trust subnet to the trust interface on the firewall so that internet-bound traffic is always inspected by the firewall. The default configuration includes two example Security Policy rules—the outbound-default rule allows all traffic from the trust zone to the untrust zone on the application default port, and the inbound-default rule allows all web-browsing traffic from the untrust zone to the trust zone, after inspecting traffic with the default Antivirus, Anti-spyware, and Vulnerability Protection security profiles. The firewall also forwards all files that are intercepted with the inbound or outbound rule to the WildFire public cloud for analysis. Both rules include a URL Filtering profile that blocks all traffic to the URL categories copyright-infringement, dynamic-dns, extremism, malware, phishing, and unknown. In addition to these security profiles, both Security policy rules are enabled to log at session end and to forward Threat and WildFire Submissions logs as security alerts to the Azure Security Center dashboard.To make practical use of this integration and Deploy a VM-Series Firewall Based on an Azure Security Center Recommendationwithin the same resource group as the workloads you want to secure, you can stage a workload with a public IP address that is exposed to the internet. When Azure Security Center detects the security risk, it triggers a recommendation to deploy a next-generation firewall, and you can then deploy the VM-Series firewall in a new resource group into which you can add your workloads later. You must then delete the workload that you staged to trigger the recommendation. - Select a VM-Series firewall that you have already deployed for securing your workloads. If you have a Standard tier of Azure Security Center subscription, Azure Security Center discovers and displays all existing VM-Series firewalls that you have deployed either from the Azure Marketplace or using a customized deployment with Azure CLI, PowerShell or ARM template. The firewalls within your Azure subscription are grouped under Security Solutions on the Azure Security Center dashboard.Microsoft Azure does not support the discovery of existing firewalls with the Free tier subscription.

To Connect an Existing VM-Series Firewall From Azure Security Center, you must set up a Linux virtual machine and configure Syslog forwarding to forward firewall logs in the Common Event Format as alerts to Azure Security Center. The additional configuration enables a single pane of glass view for monitoring all your Azure assets.
Forwarding a large volume of logs to Azure Security Center,
may result in additional subscription cost to you.
