Storage Account – Enforce Minimum TLS Version
This check ensures that Azure Storage Accounts enforce a minimum TLS version of TLS 1.2. Using older TLS versions can expose storage services to known vulnerabilities and weak encryption.
Check Details
- Resource: Storage Account
- Check: Enforce Minimum TLS Version
- Risk: Use of deprecated TLS versions may allow attackers to exploit weak encryption
Remediation via Azure Portal
-
Log in to the Azure Portal.
-
Navigate to Storage accounts and select the affected
storage account.
-
In the left menu, click on Configuration under Settings.
-
Locate the Minimum TLS version setting and select
TLS 1.2.
- Click Save to apply the changes.
Remediation via Azure CLI
-
Open Azure Cloud Shell in the Azure Portal.
-
Run the following command to enforce TLS 1.2:
az storage account update \ --name <storage-account-name> \ --resource-group <resource-group-name> \ --min-tls-version TLS1_2
Replace <storage-account-name> and
<resource-group-name> with your actual values.
