Description:
The /etc/passwd- file contains backup user account information.
Rationale:
It is critical to ensure that the /etc/passwd- 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 or
more restrictive:
# stat /etc/passwd-Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
Remediation:
Run the following command to set permissions on /etc/passwd- :
# chown root:root /etc/passwd-
# chmod u-x,go-rwx /etc/passwd-
Parameter:
[110000000, root, root]
Technical Mechanism:
Run the following command to set permissions on /etc/passwd- :
# chown root:root /etc/passwd-
# chmod u-x,go-rwx /etc/passwd-
