Description
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.
ℹ️ Check
Verify that the "/etc/passwd-" file has mode "0644" or less permissive with the following command:
$ stat -c "%#a %n" /etc/passwd-
0644 /etc/passwd-
If a value of "0644" or less permissive is not returned, this is a finding.
✔️ Fix
Change the mode of the file "/etc/passwd-" to "0644" by running the following command:
$ chmod 0644 /etc/passwd-
