Re: FTP server side logging?

[Loyd Goodbar <loyd@xxxxxxxxxxxxxx>]

I'm convinced!

I was sorely mistaken in my assumptions on how FTP sent commands to the
server. Vern, Rob, Scott, and James pointed out commands are translated at the
client. Scott gave an eloquent and detailed explanation of what transpires
without going through the RFC. And I'm grateful. :)

I needed to accomplish two objectives.

1. A prior audit recommendation was we turn off FTP entirely. This is not
possible as one of our customer's requirements is they "push" EDI data on our
system via FTP through an ANX tunnel. (The "customer" as in they dictate to us
as a supplier. Let's leave it at that, it's been working well for 2 years.) We
needed to show although we have an open hole (though encrypted via ANX), we
ensure the customer can't escape their home library. For all other users,
access is explicitly denied.

2. Prove to auditors that FTP access is truly locked down. I accomplished this
by sending QSYSOPR messages on any FTP logon attempt, successful or not. This
becomes part of our daily security monitoring routines. Looking toward the
future, I wanted to log all FTP activity for forensics and documentation. I
modified Rob's audit file and added logging of all activity to the file, based
on the exit program data. (As a side note, it's really cool that a file can be
created with UPDATE(*NO) and DELETE(*NO), so it becomes a write-only file.
Combined with PUBLIC(*EXCLUDE) authority, it's a pretty permanent log.)

In short, I have the logging I need through the FTP exit program, and it works
great. Already in production, and saw my EDI users post data to the system.

Thanks for putting up with my stubborn questioning!
