Description TLS 1.0 and 1.1 are out-of-date protocols that do not support modern cryptographic algorithms. Disabling inbound TLS 1.0 and 1.1 traffic helps secure apps in an App Service Environment.

Azure_Security_Benchmark_v3.0 DP-3 Azure_Security_Benchmark_v3.0_DP-3 Microsoft cloud security benchmark DP-3 Data Protection DP-3 Encrypt sensitive data in transit Shared **Security Principle:** Protect the data in transit against 'out of band' attacks (such as traffic capture) using encryption to ensure that attackers cannot easily read or modify the data. Set the network boundary and service scope where data in transit encryption is mandatory inside and outside of the network. While this is optional for traffic on private networks, this is critical for traffic on external and public networks. **Azure Guidance:** Enforce secure transfer in services such as Azure Storage, where a native data in transit encryption feature is built in. Enforce HTTPS for workload web application and services by ensuring that any clients connecting to your Azure resources use transportation layer security (TLS) v1.2 or later. For remote management of VMs, use SSH (for Linux) or RDP/TLS (for Windows) instead of an unencrypted protocol. Note: Data in transit encryption is enabled for all Azure traffic traveling between Azure datacenters. TLS v1.2 or later is enabled on most Azure PaaS services by default. **Implementation and additional context:** Double encryption for Azure data in transit: https://docs.microsoft.com/azure/security/fundamentals/double-encryption#data-in-transit Understand encryption in transit with Azure: https://docs.microsoft.com/azure/security/fundamentals/encryption-overview#encryption-of-data-in-transit Information on TLS Security: https://docs.microsoft.com/security/engineering/solving-tls1-problem Enforce secure transfer in Azure storage: https://docs.microsoft.com/azure/storage/common/storage-require-secure-transfer?toc=/azure/storage/blobs/toc.json#require-secure-transfer-for-a-new-storage-account n/a link 31
