AIX

I find it alarming that an audit company has to ask that, since they're supposed to know it. 

"staff" is the default group when you create an user without specifying a group, other than that it has no special meaning.

As to being assigned to parameters that grant high privileges, it shouldn't be done, for the same reason that you should do the same with the "users" group in linux or the "Everyone" group in windows.

In IBM AIX, the staff group is often the default primary group for new users unless otherwise specified during user creation. Its purpose is relatively neutral—it’s a non-administrative group that has no inherent special permissions or privileges on its own. However, associating it with high-privilege software parameters could pose significant security risks.

Key Considerations for the staff Group:

1. Default Membership:
   Many users may belong to the staff group by default, including non-privileged users. This makes it a broad membership group akin to Linux's users group or Windows' Everyone group.

2. Access Risk:
   If the staff group is assigned high-privilege roles, software parameters, or access to critical resources, all users within this group would inherit those privileges. This violates the principle of least privilege and opens up a broad attack surface.

3. Audit Concerns:
   Auditors typically flag such configurations because they allow unintended privilege escalation. The group membership is generally too broad for fine-grained access control, making it a poor choice for assigning sensitive or critical roles.

4. Security Misconfiguration:
   Granting staff high privileges could lead to unauthorized access if:

   • Accounts in this group are compromised.
   • New users are added to the group inadvertently.
   • Applications default to trusting the staff group due to configuration oversight.

Recommendations:

• Restrict Privileges: Avoid assigning staff group permissions beyond its default scope.
• Role-Specific Groups: Use custom groups with explicitly defined memberships for privileged roles.
• Auditing and Monitoring: Regularly audit group memberships and associated privileges to ensure compliance with security policies.
• Training and Awareness: Ensure administrators and auditors are aware of the potential pitfalls of using generic groups like staff for privileged roles.

If the audit company is raising this question, it’s important to assess whether any configurations currently use the staff group in a way that deviates from its intended use as a generic, non-privileged group.
