STIG ID: RHEL-10-400245  |  SRG: SRG-OS-000080-GPOS-00048 |  Severity: medium (CAT II)  |  CCI: CCI-000213 |  Vulnerability Id: V-281066

Vulnerability Discussion

The "/etc/group" file 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 has mode "0644" or less permissive with the following command:

$ sudo stat -c "%a %n" /etc/group
644 /etc/group

If a value of "0644" or less permissive is not returned, this is a finding.

Fix

Configure RHEL 10 so that the mode of the file "/etc/group" is set to "0644" by running the following command:

$ sudo chmod 0644 /etc/group
