The same risk as if you in your website allow uploads. if you allow anonymous uploads to ftp server then anyone and their nasty cousin can upload junk there.

Hi David;

The machine having IIS is under Cisco VPN, i think the user who should upload those files need VPN client and authorization to upload the files on that given folder.

My other question is that does VPN enough with FTP or do we need SFTP?

As an umbrella question, how can we limit the user in a way that he/she uploads those files under a specific folder but just that folder, no other folder in that website setup?

I would think that a vpn is sufficient protection.. Please note I do not like the microsoft ftp server I use filezilla instead and it is very easy using filezilla to have several different users including an anonymous user restricted to a directory

On usability level, what would be the trade off using FTPS against VPN?

1) Can a hacker infiltrate the network during the transmission of the files when in VPN?

2) Can a hacker infiltrate the network during the transmission of the files when when having FTPS as connection protocol?

I am not a hacker but asking just for my security sake.

David Johnson, CD, MVPOwnerCommented:
no to the above (as both are encrypted end to end) and please do not mix sftp and ftps (they are two completely different animals.
