FTP - secure, or a better way?
This is a personal matter, not related to work at all.
I am currently running an FTP server so that my Dad in Cyprus can log in and 'collect' photos and what have you that we put in the FTP folder on my machine.
We found this to be better than email as some of the pictures are quite large in size, particularly recent wedding shots we posted for him and I don't have to resize files to get them under quotas.
However, this morning I noticed someone had tried to log into the FTP server - I checked the logs, and they made 'hundreds' of attempts with different usernames and passwords, none of which worked as there is only one account, and that is my Dad's, and his password is of a secure combination anyway.
Firstly, I'm wondering how they found the FTP server in the first place, but secondly, and more importantly, is this the best and most secure way for me to get large files to my Dad?
I would prefer to not have to upload them to the 'cloud' for him to retrieve them, as that then puts some onus on me to upload them - our present system he can just log in and get them at his leisure. Is there a more secure yet just as direct way to share a folder with him so he can get to my 'stuff', and not too complicated for me to set up or him to understand? Someone mentioned a VPN to me, but I have no idea as to how I could set that up.
Or do I need not worry about this drive-by attack? The fact that they couldn't get in hasn't left me entirely happy though.
Would appreciate some thoughts.
