Prevent User Profile from using public authority

All,

Is there any way to prevent a user profile from using *PUBLIC authority?

Here's the scenario, I've got a user profile set up for JDBC use from a external web server.  All I want this profile do be able to do is call stored procedures it is specifically authorized to.

Basically, I'm concerned about *PUBLIC being expand from just "regular" users, ie. company employees, to the entire world; or at least those non employees who have logons for the web server or more worrisome, hackers that manage to breach the web server (Windows based, not by my choice ;-) 

I've thought of two ways to handle this.
1) a. Create a group profile for all my "regular" users.
   b. Grant the group profile the same authority that *PUBLIC currently has for each & every object
   c. change *PUBLIC to *EXCLUDE for every object

2) a. Grant *EXCLUDE authority to every object for this user profile (or better yet a new group profile of which this profile will be a member)

Don't forget that when I say "every object" I'm talking about IFS files and directories too.

Couple of problems:
1) Making sure new objects on the system get the correct authorities.
2) I'd imagine that there are IBM objects I shouldn't set *EXCLUDE


What I'd really like is to be able to do a CHGUSRPRF  USEPUBLIC(*NO).  But that parm doesn't exist <grin>


So how do you handle this?
