Control: Azure > CIS v3.0 > 09 - Application Services > 09.03 - Ensure 'FTP State' is set to 'FTPS Only' or 'Disabled'

Configures auditing against a CIS Benchmark item.

Level: 1

By default, App Services can be deployed over FTP. If FTP is required for an essential deployment workflow, FTPS should be required for FTP login for all App Services. If FTPS is not expressly required for the App, the recommended setting is Disabled.

FTP is an unencrypted network protocol that will transmit 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.
