The TOSS 5 /etc/passwd file must be owned by root.

The "/etc/passwd" file contains information about the users that are configured on the system. Protecting this file is critical for system security.

Verify the ownership of the "/etc/passwd" file using the following command:

$ sudo stat -c "%U %n" /etc/passwd

root /etc/passwd

If "/etc/passwd" file does not have an owner of "root", this is a finding.

Change the owner of the file /etc/passwd to root using the following command:

$ sudo chown root /etc/passwd
