A successful DNS protection strategy should secure your entire Azure environment—across all virtual networks and regions—without introducing operational friction. Azure DNS security policy with Threat Intelligence addresses these needs with:
- Consistent Protection: Applies DNS security policies across all VNETs and regions.
- Real-Time Threat Intelligence: Blocks and alerts on DNS queries to known malicious domains using continuously updated lists from Microsoft’s Security Response Center (MSRC).
- Visibility & Logging: Integrates with Log Analytics, Event Hubs, and storage accounts to log DNS activities and provide insight into blocked or risky queries.
- Low Performance Impact: Maintains high availability, low latency, and zone redundancy for name resolution services.
Core Features
- DNS Traffic Filtering: Allow, block, or alert on DNS queries at the VNET level for both public and private DNS traffic.
- Threat Intelligence Feed: Managed domain lists that automatically update to prevent resolution of malicious domains, offering proactive defense.
- Monitoring & Alerts: Capture logs and configure alerts for suspicious DNS activities, supporting SOC teams in reducing incident volume and noise.
- Infrastructure Integration: Seamless configuration alongside Azure Private DNS Zones, Private Resolver, and existing Azure networking resources.
- DevOps Friendly: Deploy and manage policies via PowerShell, CLI, .NET, Java, Python, REST, Typescript, Go, ARM, and Terraform. Pipeline support with ARM, Bicep, and Terraform for automated workflows.
Key Use Cases
- Early detection and mitigation of DNS-based security threats, including zero day and ongoing attacks.
- Visibility into DNS traffic and compromised hosts within Azure VNETs.
- Reducing operational costs compared to traditional VM-based DNS appliances.
- Integration with SOC workflows and cloud-native log management solutions.
Getting Started
- For technical documentation, guidance, and policy templates, visit the Azure DNS Security Policy docs.
- Community feedback and suggestions are welcome on the Azure networking community page.
Additional Information
- Maintained by Microsoft: Feed is continually refreshed to address new threats as they arise.
- Flexible Deployment: Policies can be created, updated, and managed using familiar IaC tooling and Azure management interfaces.
Azure DNS security policy with Threat Intelligence feed now empowers organizations to defend against DNS-based attacks with automated, cloud-native threat intelligence feeds, minimizing operational complexity and enhancing overall cloud security.
