Information

OL 9 /etc/shadow file must have mode 0000 to prevent unauthorized access.

GROUP ID: V-271817
RULE ID: SV-271817r1092163

The "/etc/shadow" file contains the list of local system accounts and stores password hashes. Protection of this file is critical for system security. Failure to give ownership of this file to root provides the designated owner with access to sensitive information, which could weaken the system security posture.

Solution

Change the mode of the file "/etc/shadow" to "0000" by running the following command:

$ sudo chmod 0000 /etc/shadow
