STIG ID: RHEL-10-400015  |  SRG: SRG-OS-000080-GPOS-00048 |  Severity: medium (CAT II)  |  CCI: CCI-000213 |  Vulnerability Id: V-281020

Vulnerability Discussion

The "/etc/group-" file is a backup file of "/etc/group", and as such contains information regarding groups that are configured on the system. Protection of this file is important for system security.

Check

Verify RHEL 10 is configured so that the "/etc/group-" file is group-owned by "root" with the following command:

$ sudo stat -c "%G %n" /etc/group-
root /etc/group-

If the "/etc/group-" file does not have a group owner of "root", this is a finding.

Fix

Configure RHEL 10 so that the group of the "/etc/group-" file is set to "root" by running the following command:

$ sudo chgrp root /etc/group-
