Ensure permissions on /etc/gshadow are configured

MittelStufe 1Manuelle Prüfungcos

Beschreibung

The /etc/gshadow file is used to store the information about groups that is critical to the security of those accounts, such as the hashed password and other security information. If attackers can gain read access to the /etc/gshadow file, they can easily run a password cracking program against the hashed password to break it. Other security information that is stored in the /etc/gshadow file (such as group administrators) could also be useful to subvert the group.
