# Your Azure SQL Is Public Right Now. ISO 27017 Demands You Fix It — Daily DevOps & .NET

**[Daily DevOps & .NET](https://daily.dev/sources/dailydevopsnet)** · [@samtrion](https://daily.dev/samtrion) · 7 min read · 0 upvotes · 0 comments

## Summary

Azure resources default to public network access, which violates ISO/IEC 27017 CLD 13.1.4 compliance requirements. The post walks through the dangerous default configurations (public SQL Server, 0.0.0.0 firewall rules, open storage accounts) and provides Bicep code to fix them using VNets, Private Endpoints, and NSGs. It also covers validation strategies including C# health checks, GitHub Actions CI/CD gates to block insecure configs, and post-deployment port scanning. Environment isolation between dev and prod using separate VNets with no peering is also emphasized as a foundational security practice.
