One has to be careful with passwords for accounts which never sign on. For
example, accounts used to run scheduled jobs only. You may want to start
out with reports only and only when you feel comfortable with the outcome,
change to automatic actions.

We do not disable accounts with too many sign on's, only the device. In
theory one could launch a Denial Of Service attack on your system by
looking at message queues in QUSRSYS and signing on three times with a
password of hatethisjob (unless they find some one user with that
password).

Our message queue monitoring software does trap some of these. Users on
our scanning devices have real difficulties signing on. We vary the
device back on three times before giving up. All automatic.
