TOSS 5 must not have the ypserv package installed.

The NIS service provides an unencrypted authentication service, which does not provide for the confidentiality and integrity of user passwords or the remote session.

Removing the "ypserv" package decreases the risk of the accidental (or intentional) activation of NIS or NIS+ services.

Verify the "ypserv" package is not installed using the following command:

$ sudo dnf list --installed ypserv

Error: No matching Packages to list

If the "ypserv" package is installed, this is a finding.

Remove the "ypserv" package using the following command:

$ sudo dnf remove ypserv
