Kirk has some good information on file transfer options using common protocols. I've got some more nominees which may be appropriate if you have long running, targeted file transfer needs -- such as a small number of particular servers that need to stay more-or-less permanently attached and transfer a lot of files.
Basically the other options would all be file sharing (NFS, CIFS/SMB, etc.) over an IPSec connection (encrypted connection). z/OS supports IPSec and also supports common network file systems like NFS, CIFS/SMB, etc. As Kirk alluded to, there are also numerous private protocol file transfer products, and they do have advantages in many missions. By the way, "secure file transfer" is a misnomer when used as we're using it here. To be more accurate for the (business-oriented/risk-analyzing) boss I would call this "encrypted transfer of raw files without custodial controls." (That name is unwieldy, but it's much closer to the truth. Perhaps someone has a shorter name that still gets the point across.) The file itself could (and usually does) contain extremely sensitive information -- things like customer records, credit card numbers, etc. Once each record is transmitted it leaves the security zone of its parent. To use an analogy, if you have the launch codes for nuclear missiles, yes, it's a good idea if you have to communicate that information to use an encrypted pipe. That's necessary but not sufficient. (The only thing encryption does is prevent somebody from intercepting the file data "over the wire.") You better be completely sure both sender and receiver apply appropriate security protocols to such sensitive information. Which is why launch codes don't get spread around a lot, nor should credit card numbers and much other financial information, medical patient records, corporate accounting (in any business), product design secrets, etc. - - - - - Timothy Sipples IBM Consulting Enterprise Software Architect Based in Tokyo, Serving IBM Japan / Asia-Pacific E-Mail: timothy.sipp...@us.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
