In addition to Don's excellent suggestions, you may want to use the IBM supplied
authority list QUSEADPAUT to regulate who can create programs that adopt
authority.  This will inhibit people from building backdoors in your system.

Other things to look at include:
    User Profiles attached to Job Descriptions (at level 30 and below)
    Unsecured message files (*CHANGE authority or higher)
    Any user profile that has *use authority to another user profile.
    *PUBLIC authority on production objects

And of course, you want to make sure that none of the programmers have, or can
aquire, *ALLOBJ authority. :)

Good Luck,

jte
