Furthermore, firewalls and load balancers didn’t exist. The inventor didn’t build the protocol with security in mind as mainframes were more common and attacks to information security were not widespread back in the 80’s. Any data sent over these channels can be exploited with a MITM (Man-in-the-middle) attack using ARP poisoning and packet sniffers. One of the reasons FTP has lasted so long is that it has so many clients available on every platform you can think of.įTP runs over two separate channels known as the command channel and the data channel, which both are unencrypted. Open standards are awesome, and the File Transfer Protocol FTP (inspite of its flaws) has been in constant use for an amazing 40 years! FTP can be a pain to run over firewalls and load balancers, so this blog explains how to configure Microsoft FTP and HAProxy.įTP (RFC 114!) was first implemented at MIT more than 40 years ago, and to this day this is still the standard protocol for file transfers.
