New Blog | Validating FTP traffic scenarios with Azure Firewall
Written by Gopikrishna Kannan (Head of Products: Azure Firewall and Firewall Manager) The Azure Firewall is a cloud-native and intelligent network firewall security service that can be integrated into many different use cases. It’s a fully stateful firewall as a service with built-in high availability and unrestricted cloud scalability that provides both east-west and north-south traffic inspection. This blog will discuss FTP scenario with Azure Firewall. FTP or File Transfer Protocol is the most common use case for enterprise customers. FTP may be configured to run in active or passive mode, which determines how the data connection is established. Azure Firewall supports both Active and Passive FTP scenarios. Passive FTP mode requires FTP client to initiate connection to the server on a specified port range. Passive FTP is the recommended approach for East - West (E-W) scenarios. In Active FTP mode, the server initiates connection to the client. This approach is typically deployed to support internet clients connecting to the FTP server running behind Azure Firewall and requires more than 250 DNAT ports (Azure Firewall DNAT rule limits) to be opened hitting load balancer limits. By default, Passive FTP is enabled, and Active FTP support is disabled to protect against FTP bounce attacks using the FTP PORT command.

New Azure Network Security and Azure Sentinel Blog Posts | Integrating Azure Sentinel/Azure Firewall
We’re excited to announce a seamless integration between Azure Firewall and Azure Sentinel. Now, you can get both detection, prevention and response automation in the form of an easy-to-deploy Azure Firewall solution for Azure Sentinel. Combining these capabilities allow you to ensure that you both prevent sophisticated threats when you can, while also maintaining an “assume breach mentality” to detect and quickly/automatically respond to cyberattacks. The Azure Firewall Solution for Azure Sentinel is now available. Please see the security community blog to learn about the new threat detections, hunting queries and automation for Azure Firewall that are included in this new solution <Optimize security with Azure Firewall solution for Azure Sentinel - Microsoft Security>. The automation capability for Azure Firewall with Azure Sentinel is provided with the new Logic App Connector and Playbook Templates. With this integration, you can automate response to Azure Sentinel incidents which contains IP addresses (IP entity), in Azure Firewall. The new Connector and Playbook templates allow security teams to get threat detection alerts directly in a Microsoft Teams Channel when one of the Playbooks attached to an Automation Rule triggers based on a Sentinel detection rule. Security incident response teams can then triage, perform one click response and remediation in Azure Firewall to block or allow IP address sources and destinations based on these alerts. To learn more about deploying, configuring and using the automation for Azure Firewall with the new Custom Logic App connector and Playbooks, please review the instructions in the blog here <Automated Detection and Response for Azure Firewall with the New Logic App Connector and Playbooks (microsoft.com)>.
