Title

RHEL 10 must enforce mode "0000" or less permissive for the "/etc/gshadow-" file to prevent unauthorized access.

Control

Verify RHEL 10 is configured so that the "/etc/gshadow-" file has mode "0000" with the following command: $ sudo stat -c "%a %n" /etc/gshadow- 0 /etc/gshadow- If a value of "0" is not returned, this is a finding.

Discussion

The "/etc/gshadow-" file is a backup of "/etc/gshadow", and as such contains group password hashes. Protection of this file is critical for system security.
