For the past 5 years or so, we have been transferring 3 files from our Miami office (Unix platform) to our Cayman Islands office (Windows Server 2008 Standard SP2) on a daily basis via FTP using a login and password.
Our current setup is as follows: In the Cayman office we have a domain account set up (ftpusr) which has been given read/write and list access to a directory on the server. The unix system in Miami will use this account to transfer the 3 files to the Cayman office server daily.
We now want to use SFTP to transfer these files, also and most importantly we DO NOT want to use credentials (a login and password) to authenticate with the other side. Instead we want to use some other method of authentication. Like a certificate or key or something else that would make authentication easy and secure.
I need options/ideas on how to accomplish this as I am not sure. But the below points must be met:
1. Must be SFTP
2. Must use either a “Free” third-party application or something included in Windows server 2008.
3. Cannot be an anonymous account.
Kindly advise how this can be accomplished.
About the "SFTP without credentials" thing: what about Private/Public Keys?!
