I want to summarize what we've covered in this module before continuing.
FTP active mode was the original protocol and was created in the 1970s,
long before cybersecurity was top of mind in our industry.
This operation requires the server to initiate new connections to the client,
wreaking havoc on many network designs.
As a result, securing FTP in active mode is a real challenge,
often one not worth pursuing.
In the next module, I'll introduce a simple enhancement that helps reduce the attack surface.
