Partner TechTip: Secure Your System i with Special Authorities

Why the fuss about special authorities? Skipping a discussion of *ALLOBJ for the moment, special authorities provide users with the capability to perform specialized functions. If that capability falls outside of their job responsibilities, they shouldn't have the special authority. Assigning users only the capabilities sufficient to perform their job functions is a requirement of several laws and regulations (including PCI Data Security Standards). In addition, it makes good business sense to allow users only the capabilities that they need.

*ALLOBJ is slightly different. Users assigned *ALLOBJ special authority can access all objects. Once you assign a user *ALLOBJ, that user cannot be prevented from accessing any object on the system. I heard the other day of an administrator trying to restrict programmers' access to several libraries. However, they had been assigned *ALLOBJ. Given the way i5/OS performs its authority checks, users with *ALLOBJ will always have access to an object. Attempting to restrict their access was a waste of time.

Why are special authorities out of control? Because most profiles are not created from "scratch." Most profiles are created by copying another profile. So if the original profile has more special authorities than necessary, the new profile will also have those special authorities.

Here are the capabilities (special authorities) you can grant users and the functions they provide:

Special Authorities and Their Functions
*AUDIT
Configuration of i5/OS auditing attributes
*IOSYSCFG
Communications configuration and management
*JOBCTL
Management of a job on the system
*SAVSYS
Ability to save and restore the entire system or any object on the system, regardless of authority to the object
*SECADM
Create/change/delete user profiles
*SERVICE
Ability to use Service Tools, perform a service trace, debug another user's job
*SPLCTL
Access to every spooled file on the system regardless of authority to the outq (the "*ALLOBJ" of spooled files)
*ALLOBJ
Access to every object on the system. It is impossible to prevent an *ALLOBJ user from accessing an object!

 

Taking Control

The best way to rework the assignment of special authorities is to first assign users to a role. Typical roles include system administrator, operator, programmer, change control administrator, database administrator, analyst, and end user. Next, list the tasks each role typically performs. Finally, list the special authorities required by each task. This determines which special authorities each role requires.

How Skyview Policy Minder Can Help

To detect when users have gained special authorities they shouldn't have, there are two ways that Policy Minder can help.

First, you can define a user profile template, choosing to include all users of a particular user class (such as *SECOFR or *USER) or a specific group; then, specify which special authorities the users in the user class or group are to have. For example, you may specify that all users in the *SYSOPR user class are to have *SAVSYS and *JOBCTL special authorities. When you run a compliance check, the special authorities assigned to the profiles belonging to the specified user will be checked against the template (policy) you created. Any profile's special authorities that don't match the policy will be flagged as being out of compliance with the policy.

The second way that you can check special authorities with Policy Minder is to create a slightly different user profile template. In this template, you include all users who have a specific special authority—for example, *ALLOBJ. Then you specify *NO for the attribute "Allow new user profile." The first time you run a compliance check, it establishes the baseline of all users who currently have the special authority (in our example, *ALLOBJ.) The next time you run a compliance check, any profile that has been created with, changed to have, or restored with *ALLOBJ assigned will be flagged as *NEW and, therefore, out of compliance. This method is especially helpful in keeping track of the very powerful special authorities such as *ALLOBJ as well as the special authorities auditors may want to limit, such as *AUDIT.
