[jira] [Commented] (NIFI-4621) Allow inputs to ListSFTP

    [ https://issues.apache.org/jira/browse/NIFI-4621?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16334642#comment-16334642 ] 

Puspendu Banerjee commented on NIFI-4621:
-----------------------------------------

Requesting for comment on pros, cons and security implication.

[~soumya.ghosh] Can you provide a real life usecase for this feature? can we go for a limited number of SFTP hosts? Opening this feature for all hosts / unlimited unique sftp hosts could become a stepping stone for DDoS attack.

> ListSFTP supports listing of the supplied directory (Remote Path) out-of-the-box on the supplied "Hostname" using the 'Username" and 'Password" / "Private Key Passphrase". 
> The password can change at a regular interval (depending on organization policy) or the Hostname or the Remote Path can change based on some other requirement.
> This is a case to allow ListSFTP to leverage the use of Nifi Expression language so that the values of Hostname, Password and/or Remote Path can be set based on the attributes of an incoming flow file.
