Discussion

The "/etc/passwd-" file is a backup file of "/etc/passwd", and as such, contains information about the users that are configured on the system. Protection of this file is critical for system security.

Check Content

Verify the group ownership of the "/etc/passwd-" file with the following command:

$ stat -c "%G %n" /etc/passwd-

root /etc/passwd-

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

Fix Text

Change the group of the file /etc/passwd- to root by running the following command:

$ chgrp root /etc/passwd-
