Tidbit #1: After disclosing so much information about your client, you
might check with them to see if they are still indeed your client. When
posting to newlists, don't offer up so much information that will allow
others to make a concerted effort to hack your systems, or the systems of
your clients, assuming that anyone on this list can determine who you are,
or who you're working for.

Tidbit#2: Review the list of books under the SecurityFocus Library - AS/400
section. There are some good resources there. Some of the IBM Redbooks
are very useful too (they should be listed in the same area).
