Just curious, I have a single installation of Dot Net Nuke on my servers and I currently have many different clients setup with their own portal IDs.

I'm wondering if I gave FTP access to one of my clients to his own portal ID if there are any files in his folders that he could potentially change or update that would bring down all the other portal IDs?  I'm particularly curious about the ASCX files but if there are any others I'd like to know.

FTP is always dangerous, uncontrolled upload may affect security of the installation - and, if not properly configured, of the whole server.

thanks sebastian, but wouldnt that be true for FTP access for any website for any platform?  I'm talking more specifically about DNN and any files that may effect all the portals setup for that single installation of DNN. 

also, you mentioned that "If not properly configured" which would suggest that there is a proper configuration.... what would a good configuration be for FTP access to a single client to a single portal ID?

as long as anyone is able to upload into DNN directory (besides app_data), code will be executed - this is a security risk, AFAIK you cannot control, which file types are uploaded (or renamed) on the server. Executed code may connect to the database and e.g. retrieve host password, i.e. it is a high risk. a better idea might be using a subdomain without execute permission and grant ftp upload for it.

To make ftp as secure as possible, use strong passwords, if possible use secure ftp, and make sure, user has access to selected directories only.
