This port can be opened by enabling FTP. Authentication is performed on port 21 and defined by the FTP protocol. Port 21 is the control port on which the FTP service listens for incoming FTP requests. Allows alert notifications through SFTP (FTP over SSH). SFTP is a client/server protocol. Users can use SFTP to perform file transfers on an appliance on the local subnet. Also provides outgoing FTP control connection. If closed, FTP will not be available. Used to transmit DNS queries to the DNS server. If closed, DNS name resolution will not work. Required for SMB v1. Required for Kerberos authentication services. Opened by the standard portmapper or rpcbind service and is an ancillary appliance network service. It cannot be Port usage 27
