Ensure 'FTP state' is set to 'FTPS only' or 'Disabled'

HochStufe 1Manuelle Prüfungazure

Beschreibung

By default, App Service supports deployment over FTP. If FTP is essential for a deployment workflow, FTPS should be enforced for all App Service deployment slots. If FTPS is not explicitly required, the recommended setting is Disabled. FTP is an unencrypted network protocol that transmits data—including passwords—in clear text. The use of this protocol can lead to both data and credential compromise and can present opportunities for exfiltration, persistence, and lateral movement.
