I think you want *PUBLIC *EXCLUDE authority for all objects!

Then an 'owner' profile that owns all programs and data objects, and has all rights to programs and data objects.

You then have a 'user' profile (not necessarily QUSER) that has *USE rights to data and programs.

The programs are all owned by the 'owner' profile, and they all run as USRPRF(*OWNER).

The 'users' then are able to run the programs, which, using adopted authority, can update the data objects.

This keeps 'strangers' out of your data, but lets 'users' do what they need to do.

IFS has its own rules.

Subject: Use of adopted profiles

Is there a document that describes how the adopted authority works and
maybe best practices? I am reviewing a project to lock the system down and
it has been a long time since I last set up a highly secure system.

My plan is to
- revoke all authorities from user libraries, objects and the IFS.
- Grant authority to a group profile.
- The group profile will own all objects.
- Users will have none or limited authority directly.
- When users signon to the menu, the menu program will grant authority
whilst using the job. When they sign off, they will have no authority.

Objective:
- Prevent unauthorized access to the system
- There are users on multiple systems accessing this system and its wide
open. - Plan to grant authority to objects only where required example read
rights to file where a remote system needs to access files to retrieve data
and so on.

The same will apply to the IFS.

What are the best practices today? I know some folk don't like this
approach but it is one of the cleanest and easiest approaches to implement
and maintain.

TIA
