Title

RHEL 10 must be configured so that the "/etc/shadow-" file is owned by "root".

Control

Verify RHEL 10 is configured so that the "/etc/shadow-" file is owned by "root" with the following command: $ sudo stat -c "%U %n" /etc/shadow- root /etc/shadow- If the "/etc/shadow-" file does not have an owner of "root", this is a finding.

The "/etc/shadow-" file is a backup file of "/etc/shadow", and as such contains the list of local system accounts and password hashes. Protection of this file is critical for system security.
