Description​

Basic Authentication provides the ability to create identities and authentication for an App Service without a centralized identity provider. For a more effective, capable, and secure solution for identity, authentication, authorization, and accountability, a centralized identity provider such as Entra ID is strongly advised.

Rationale​

Basic Authentication introduces an identity silo which can produce privileged access to a resource. This can be exploited in numerous ways and represents a significant vulnerability and attack vector.

Impact​

An identity provider that the App Service can use for authenticating users is required.

Audit​

From Azure Portal​
  1. Search for and open App Services from the search bar.
  2. For each App Service listed, do the following:
  3. Select the App Service name.
  4. Under the Settings menu item, click on Configuration.
  5. Under the General settings tab, scroll down to locate the two Basic Auth settings:
    • SCM Basic Auth Publishing Credentials.
    • FTP Basic Auth Publishing Credentials.

    • Set the SCM Basic Auth Publishing Credentials radio button to Off.
    • Set the FTP Basic Auth Publishing Credentials radio button to Off.

CAUTION: The new settings are not yet applied. Applying them may cause your App Service resource to restart. Proceed with caution. Click the Save button, then click Continue to apply the updated configuration. Repeat this procedure for each App Service.
