Public Preview: Audit and Enable Windows Recovery Environment (WinRE) for Azure Arc-enabled Servers
Windows Recovery Environment is a secure, isolated partition that enables diagnostics and repair when a system encounters critical failures – such as a stop error (commonly known as the blue screen of death). WinRE provides a reliable fallback mechanism for mission-critical workloads, allowing IT administrators to recover systems quickly and securely. With this Public Preview, Azure Arc introduces a set of Azure Policies that allow organizations to audit and enable WinRE across their fleet of Arc-enabled Windows Servers. These policies are powered by the Machine Configuration component of the Azure Connected Machine agent, which ensures secure and compliant configuration enforcement. Through the Azure Policy, the Azure Connected Machine agent detects whether WinRE is configured and reports its health status. If WinRE is not configured and the WinRE partition has been provisioned, customers can enable WinRE through the Azure Policy. These Azure Policies are available at no additional cost for servers covered under: Windows Server 2012 Extended Security Updates (ESUs) Microsoft Defender for Servers Plan 2 Windows Server Software Assurance attestation Windows Server Pay-as-you-Go licensing For other servers, these policies will incur charges associated with Azure Machine Configuration. To get started, deploy and assign these Azure Policies to Azure Arc-enabled servers in your existing subscription.

We’re excited to announce the General Availability of Arc gateway for Arc‑enabled servers. Arc gateway dramatically simplifies the network configuration required to use Azure Arc by consolidating outbound connectivity through a small, predictable set of endpoints. For customers operating behind enterprise proxies or firewalls, this means faster onboarding, fewer change requests, and a smoother path to value with Azure Arc. What’s new: To Arc‑enable a server, customers previously had to allow 19 distinct endpoints. With Arc gateway GA, you can do the same with just 7, a ~63% reduction that removes friction for security and networking teams. Why This Matters Organizations with strict outbound controls often spend days, or weeks, coordinating approvals for multiple URLs before they can onboard resources to Azure Arc. By consolidating traffic to a smaller set of destinations, Arc gateway: Accelerates onboarding for Arc‑enabled servers by cutting down the proxy/firewall approvals needed to get started. Simplifies operations with a consistent, repeatable pattern for routing Arc agent and extension traffic to Azure. How Arc gateway works Arc gateway introduces two components that work together to streamline connectivity: Arc gateway (Azure resource): A single, unique endpoint in your Azure tenant that receives incoming traffic from on‑premises Arc workloads and forwards it to the right Azure services. You configure your enterprise environment to allow this endpoint. Azure Arc Proxy (on every Arc‑enabled server): A component of the connected machine agent that routes agent and extension traffic to Azure via the Arc gateway endpoint. It’s part of the core Arc agent; no separate install is required. At a high level, traffic flows: Arc agent → Arc Proxy → Enterprise Proxy → Arc gateway → Target Azure service. Scenario Coverage As part of this GA release, common Arc‑enabled Server scenarios are supported through the gateway, including: Windows Admin Center SSH Extended Security Updates (ESU) Azure Extension for SQL Server For other scenarios, some customer‑specific data plane destinations (e.g., your Log Analytics workspace or Key Vault URLs) may still need to be allow‑listed per your environment. Please consult the Arc gateway documentation for the current scenario‑by‑scenario coverage and any remaining per‑service URLs. Over time, the number of scenarios filly covered by Arc gateway will continue to grow. Get started Create an Arc gateway resource using the Azure portal, Azure CLI, or PowerShell. Allow the Arc gateway endpoint (and the small set of core endpoints) in your enterprise proxy/firewall. Onboard or update servers to use your Arc gateway resource and start managing them with Azure Arc. For step‑by‑step guidance, see the Arc gateway documentation on Microsoft Learn. You can also watch a quick Arc gateway Jumpstart demo to see the experience end‑to‑end. FAQs Does Arc gateway require new software on my servers? No additional installation - Arc Proxy is part of the standard connected machine agent for Arc‑enabled servers. Will every Arc scenario route through the gateway today? Many high‑value server scenarios are covered at GA; some customer‑specific data plane endpoints (for example, Log Analytics workspace FQDNs) may still need to be allowed. Check the docs for the latest coverage details. When will Arc gateway for Azure Local be GA? Today! Please refer to the Arc gateway GA on Azure Local Announcement to learn more. When will Arc gateway for Arc-enabled Kubernetes be GA? We don't have an exact ETA to share quite yet for Arc gateway GA for Arc-enabled Kubernetes. The feature is currently still in Public Preview.

Hello Folks, As IT pros, we’re always looking for ways to reduce complexity and improve security in our infrastructure. One area that’s often overlooked is how our services authenticate with each other. Especially when it comes to Azure File Sync. In this post, I’ll walk you through how Managed Identities can simplify and secure your Azure File Sync deployments, based on my recent conversation with Grace Kim, Program Manager on the Azure Files and File Sync team. Why Managed Identities Matter Traditionally, Azure File Sync servers authenticate to the Storage Sync service using server certificates or shared access keys. While functional, these methods introduce operational overhead and potential security risks. Certificates expire, keys get misplaced, and rotating credentials can be a pain. Managed Identities solve this by allowing your server to authenticate securely without storing or managing credentials. Once enabled, the server uses its identity to access Azure resources, and permissions are managed through Azure Role-Based Access Control (RBAC). Using Azure File Sync with Managed Identities provides significant security enhancements and simpler credential management for enterprises. Instead of relying on storage account keys or SAS tokens, Azure File Sync authenticates using a system-assigned Managed Identity from Microsoft Entra ID (Azure AD). This keyless approach greatly improves security by removing long-lived secrets and reducing the attack surface. Access can be controlled via fine-grained Azure role-based access control (RBAC) rather than a broadly privileged key, enforcing least-privileged permissions on file shares. I believe that Azure AD RBAC is far more secure than managing storage account keys or SAS credentials. The result is a secure-by-default setup that minimizes the risk of credential leaks while streamlining authentication management. Managed Identities also improve integration with other Azure services and support enterprise-scale deployments. Because authentication is unified under Azure AD, Azure File Sync’s components (the Storage Sync Service and each registered server) seamlessly obtain tokens to access Azure Files and the sync service without any embedded secrets. This design fits into common Azure security frameworks and encourages consistent identity and access policies across services. In practice, the File Sync managed identity can be granted appropriate Azure roles to interact with related services (for example, allowing Azure Backup or Azure Monitor to access file share data) without sharing separate credentials. At scale, organizations benefit from easier administration. New servers can be onboarded by simply enabling a managed identity (on an Azure VM or an Azure Arc–connected server) and assigning the proper role, avoiding complex key management for each endpoint. Azure’s logging and monitoring tools also recognize these identities, so actions taken by Azure File Sync are transparently auditable in Azure AD activity logs and storage access logs. Given these advantages, new Azure File Sync deployments now enable Managed Identity by default, underscoring a shift toward identity-based security as the standard practice for enterprise file synchronization. This approach ensures that large, distributed file sync environments remain secure, manageable, and well-integrated with the rest of the Azure ecosystem. How It Works When you enable Managed Identity on your Azure VM or Arc-enabled server, Azure automatically provisions an identity for that server. This identity is then used by the Storage Sync service to authenticate and communicate securely. Here’s what happens under the hood: The server receives a system-assigned Managed Identity. Azure File Sync uses this identity to access the storage account. No certificates or access keys are required. Permissions are controlled via RBAC, allowing fine-grained access control. Enabling Managed Identity: Two Scenarios Azure VM If your server is an Azure VM: Go to the VM settings in the Azure portal. Enable System Assigned Managed Identity. Install Azure File Sync. Register the server with the Storage Sync service. Enable Managed Identity in the Storage Sync blade. Once enabled, Azure handles the identity provisioning and permissions setup in the background. Non-Azure VM (Arc-enabled) If your server is on-prem or in another cloud: First, make the server Arc-enabled. Enable System Assigned Managed Identity via Azure Arc. Follow the same steps as above to install and register Azure File Sync. This approach brings parity to hybrid environments, allowing you to use Managed Identities even outside Azure. Next Steps If you’re managing Azure File Sync in your environment, I highly recommend transitioning to Managed Identities. It’s a cleaner, more secure approach that aligns with modern identity practices. ✅ Resources 📚 https://learn.microsoft.com/azure/storage/files/storage-sync-files-planning 🔐 https://learn.microsoft.com/azure/active-directory/managed-identities-azure-resources/overview ⚙️ https://learn.microsoft.com/azure/azure-arc/servers/overview 🎯 https://learn.microsoft.com/azure/role-based-access-control/overview 🛠️ Action Items Audit your current Azure File Sync deployments. Identify servers using certificates or access keys. Enable Managed Identity on eligible servers. Use RBAC to assign appropriate permissions. Let me know how your transition to Managed Identities goes. If you run into any snags or have questions, drop a comment. Cheers! PierreFirmware Analysis now Generally Available
Back in June, we announced the public preview of firmware analysis, a new capability available through Azure Arc to help organizations gain visibility into the security of their Internet of Things (IoT), Operational Technology (OT), and network devices. Today, we are excited to announce that firmware analysis is generally available (GA) for all Azure customers. In modern industrial environments, firmware security is a foundational requirement. IoT sensors and smart devices collect the data fueling AI-driven insights; if those devices aren’t secure, your data and operational continuity are at risk. During the preview, we heard from many customers who used firmware analysis to shine a light into their device software and address hidden vulnerabilities before attackers or downtime could strike. With general availability, firmware analysis is ready to help organizations fortify the “blind spots” in their infrastructure – from factory-floor sensors to branch office routers – by analyzing the software that runs on those devices. What Firmware Analysis Does for You Firmware analysis examines the low-level software (firmware) that powers IoT, OT and network devices, with no agent required on the device. You can upload a firmware image (for example, an extracted embedded Linux image), and the cloud service performs an automated security inspection. Key features include: Software inventory & vulnerability scanning: The service builds a Software Bill of Materials (SBOM) of components within the firmware and checks each component against known CVEs (Common Vulnerabilities and Exposures). This quickly surfaces any known vulnerabilities in your device’s software stack so you can prioritize patching those issues. Security configuration and hardening check: Firmware analysis evaluates how the firmware binaries are built, looking for security hardening measures (e.g. stack protections, ASLR) or dangerous configurations. If certain best practices are missing, the firmware might be easier to exploit – the tool flags this to inform the device manufacturer or your security team. Credential and secrets discovery: The analysis finds any hard-coded credentials (user accounts/password hashes) present in the firmware, as well as embedded cryptographic material like SSL/TLS certificates or keys. These could pose serious risks – for instance, default passwords that attackers could exploit (recall the Mirai botnet using factory-default creds) are identified so you can mitigate them. Any discovered certificates or keys can indicate potentially insecure design if left in production firmware. Comprehensive report: All security findings – from the Software Bill of Materials (SBOM), list of vulnerabilities to hardening recommendations and exposed secrets – are provided in a detailed report for each firmware image analyzed. This gives device makers and operators actionable intelligence to improve their device security posture. In short, firmware analysis provides deep insights into the contents and security quality of device firmware. It turns opaque firmware into transparent data, helping you answer, “What’s really inside my device software?” so you can address weaknesses proactively. What’s New and Licensing We’ve been hard at work making firmware analysis even better as we move to GA. Based on preview feedback, we’ve addressed bugs, implemented usability suggestions and improved the firmware analysis SDKs, CLI and PowerShell extensions. A new Azure resource called “firmware workspace” now stores analyzed firmware images. Firmware analysis workspaces are currently available as a Free Firmware Analysis Workspace SKU with capacity limits. Getting Started If you have IoT, OT and network devices in your environment, use firmware analysis to test just how secure your devices are. Getting started is easy: access firmware analysis by searching “firmware analysis” in the Azure portal, or access using this link. Onboard your subscription and then upload firmware images for analysis. For a step-by-step tutorial, visit our official documentation. The service currently supports embedded Linux-based images up to 1GB in size. We want to thank all the preview participants who tested firmware analysis and provided feedback. You helped us refine the service for GA and we’re thrilled to make this powerful tool broadly available to help secure IoT, OT and network devices around the world. We can’t wait to see how you put it to work. As always, we value your feedback, so please let us know what you think.
