I'm pretty sure we don't encrypt any data. Much of our backups are

to be converted.
So far, no one has givin me any companies that do this sort of thing.
Does anyone know of any? Of course, most of you hopefully have never
had to deal with this sort of thing.
Eric,
I have not heard of any MF "application" that does field level
security except for possibly DB2. This is not to say their isn't just
that it is unusual, IMO. There may be some user code in CICS that
selectively displays a field (or not) but that seems to be a
transaction type security . There are just too many ways you can
access a file that is one of the reasons why people need RACF (or
other security package).
Way back in the early 70's I had to have a top secret clearance from
the Army so I could help programmers debug their code. One of the
dumps I had to look at had the number of toilet paper rolls that was
in stock. I asked the programmer why that was top secret and he said
the SOviets could figure out how many people the US had in Germany. I
suggested to go through parking lots and count the green plates and
you would have a better idea.
There were other nonsensical issues, but you get the idea.
