All AIX Group Identifiers (GIDs) referenced in the /etc/passwd file must be defined in the /etc/group file.
Severity | Group ID | Group Title | Version | Rule ID | Date | STIG Version |
|---|---|---|---|---|---|---|
| medium | V-215339 | SRG-OS-000480-GPOS-00227 | AIX7-00-003033 | SV-215339r991589_rule | 2026-02-06 | 3 |
Description
If a user is assigned the GID of a group not existing on the system, and a group with that GID is subsequently created, the user may have unintended rights to the group.
ℹ️ Check
Verify that there are no GIDs referenced in "/etc/passwd" that are not defined in "/etc/group":
# cut -d: -f4 /etc/passwd
0
1
2
3
4
203
204
# cut -d: -f3 /etc/group
0
1
2

204
If there are GID's listed in the "/etc/passwd" file that are not listed in the "/etc/group" file, this is a finding.
✔️ Fix
Add a group to the system for each GID referenced without a corresponding group by running "mkgroup" command.
