>> I was just discussing this with someone else, and was wondering if
anyone out there is using security level 50 on the AS/400.  What
advantages does 50 provide over level 40?  What are the considerations
in moving from 40 to 50?  From 30 to 50?  All insight appreciated... <<


>From what I remember of the level 50 announcement, it provides
compliance with some DOD requirements that are of little or no value to
a commercial shop, and cause a fair amount of overhead. One of the
things that I remember it doing is modifying the delete processing so
that if you run DLTF, it will not only remove the object definition, but
write a constant (x'EF' I think??) to the data space not once, but
multiple times. I haven't thought much about it since. I wonder if
anyone knows of anything it does that is really useful. Going from 30 to
50 will give you the aforementioned benifits also, but in addition, my
preceived main benifit is that you'll get enforced compliance so that no
unholy (not blessed by IBM) interfaces to system code can be run. I like
that one.
