| 2 | # |
| 3 | # Description |
| 4 | # =========== |
| 5 | # The /etc/shadow- file is used to store backup information about user |
| 6 | # accounts that is critical to the security of those accounts, such as the |
| 7 | # hashed password and other security information. |
| 8 | # |
| 9 | # Rationale |
| 10 | # ========= |
| 11 | # It is critical to ensure that the /etc/shadow- file is protected from |
| 12 | # unauthorized access. Although it is protected by default, the file |
| 13 | # permissions could be changed either inadvertently or through malicious actions. |
| 14 | # |
| 15 | # Audit |
| 16 | # ===== |
| 17 | # Run the following command and verify Uid and Gid are both 0/root and |
| 18 | # Access is 600 or more restrictive: |
| 19 | # |
| 20 | # # stat /etc/shadow- |
| 21 | # Access: (0600/-rw-------) Uid: (0/root) Gid: (0/root) |
| 22 | # |
| 23 | # Remediation |
| 24 | # =========== |
| 25 | # Run the following command to set permissions on /etc/shadow- : |
| 26 | # |
| 27 | # # chown root:root /etc/shadow- |
| 28 | # # chmod 600 /etc/shadow- |
| 29 | # |

| 31 | linux: |
| 32 | system: |
| 33 | file: |
| 34 | /etc/shadow-: |
| 35 | user: 'root' |
| 36 | group: 'root' |
| 37 | mode: '0600' |
