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
Rationale:
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.
Fix:
Run the following commands to set permissions on /etc/gshadow- : # chown root:root /etc/gshadow- # chmod g-wx,o-rwx /etc/gshadow-
Parameter:
[110100000, 42, 0]
Technical Mechanism:
Run the following commands to set permissions on /etc/gshadow- : # chown root:root /etc/gshadow- # chmod g-wx,o-rwx /etc/gshadow-
