Description Disabling the public endpoint allows you to restrict access to your Storage Sync Service resource to requests destined to approved private endpoints on your organization's network. There is nothing inherently insecure about allowing requests to the public endpoint, however, you may wish to disable it to meet regulatory, legal, or organizational policy requirements. You can disable the public endpoint for a Storage Sync Service by setting the incomingTrafficPolicy of the resource to AllowVirtualNetworksOnly.

Azure_Security_Benchmark_v3.0 NS-2 Azure_Security_Benchmark_v3.0_NS-2 Microsoft cloud security benchmark NS-2 Network Security NS-2 Secure cloud services with network controls Shared **Security Principle:** Secure cloud services by establishing a private access point for the resources. You should also disable or restrict access from public network when possible. **Azure Guidance:** Deploy private endpoints for all Azure resources that support the Private Link feature, to establish a private access point for the resources. You should also disable or restrict public network access to services where feasible. For certain services, you also have the option to deploy VNet integration for the service where you can restrict the VNET to establish a private access point for the service. **Implementation and additional context:** Understand Azure Private Link: https://docs.microsoft.com/azure/private-link/private-link-overview n/a link 126
