Description:
The /etc/gshadow- file is used to store backup information about groups that is critical to
the security of those accounts, such as the hashed password and other security
information.
Rationale:
It is critical to ensure that the /etc/gshadow- file is protected from unauthorized access.
Although it is protected by default, the file permissions could be changed either
inadvertently or through malicious actions.
Audit:
Run the following command and verify verify Uid is 0/root, Gid is 0/root or
/shadow, and Access is 640 or more restrictive:
# stat /etc/gshadow- Access: (0640/-rw-r-----) Uid: ( 0/ root) Gid: ( 0/ root)
Remediation:
Run the one of the following chown commands as appropriate and the chmod to set
permissions on /etc/gshadow- :
# chown root:root /etc/gshadow-
# chown root:shadow /etc/gshadow-
# chmod o-rwx,g-rw /etc/gshadow-
Parameter:
[110100100, root, root]
Technical Mechanism:
Run the one of the following chown commands as appropriate and the chmod to set
permissions on /etc/gshadow- :
# chown root:root /etc/gshadow-
# chown root:shadow /etc/gshadow-
# chmod o-rwx,g-rw /etc/gshadow-
