Ensure 'Minimum Inbound TLS Version' is set to '1.2' or higher

HochStufe 1Manuelle Prüfungazure

Beschreibung

The TLS (Transport Layer Security) protocol secures the transmission of data over the internet using standard encryption technology. App Service apps use TLS 1.2 for the Minimum Inbound TLS Version by default and allow for the use of TLS versions 1.0, 1.1, and 1.3. NIST strongly suggests the use of TLS 1.2 and recommends the adoption of TLS 1.3. TLS 1.0 and 1.1 are outdated and vulnerable to security risks. Since TLS 1.2 and TLS 1.3 provide enhanced security and improved performance, it is highly recommended to use TLS 1.2 or higher whenever possible.

Audit from Azure Portal 1. Go to App Services. 2. Click the name of an app. 3. Under Settings, click Configuration. 4. In the General settings pane, under Platform settings, ensure that Minimum Inbound TLS Version is set to 1.2 or higher. 5. Repeat steps 1-4 for each app. Audit from Azure CLI Run the following command to list apps: az webapp list For each app, run the following command to get the TLS version setting: az webapp config show --resource-group <resource-group-name> --name <app- name> --query minTlsVersion Ensure that "1.2" or higher is returned. Audit from PowerShell Run the following command to list apps: Get-AzWebApp Run the following command to get the app in a resource group with a given name: $app = Get-AzWebApp -ResourceGroupName <resource-group-name> -Name <app-name> Run the following command to get the TLS version setting: $app.SiteConfig.MinTlsVersion Ensure that the command returns 1.2 or higher. Repeat for each app. Audit from Azure Policy If referencing a digital copy of this Benchmark, clicking a Policy ID will open a link to the associated Policy definition in Azure.

Remediate from Azure Portal 1. Go to App Services. 2. Click the name of an app. 3. Under Settings, click Configuration. 4. In the General settings pane, under Platform settings, click the drop-down next to Minimum Inbound TLS Version and select 1.2 or higher. 5. Click Save. 6. Click Continue. 7. Repeat steps 1-6 for each app requiring remediation. Remediate from Azure CLI For each app requiring remediation, run the following command to update the TLS version: az webapp config set --resource-group <resource-group-name> --name <app-name> --min-tls-version <1.2|1.3> Remediate from PowerShell For each app requiring remediation, run the following command to update the TLS version: Set-AzWebApp -ResourceGroupName <resource-group-name> -Name <app-name> - MinTlsVersion <1.2|1.3>
