======6.1.7 Ensure permissions on /etc/shadow- are configured (Scored)======
=====Profile Applicability=====
Level 1 - Server
Level 1 - Workstation
=====Description=====
The ''/etc/shadow-'' file is used to store backup information about user accounts 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/shadow-'' 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 ''Uid'' and ''Gid'' are both ''0/root'' and ''Access'' is ''600'':
# stat /etc/shadow-
Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
=====Remediation=====
Run the following command to set permissions on ''/etc/shadow-'':
# chown root:root /etc/shadow-
# chmod 600 /etc/shadow-
