I was cautious about the security of the services on my laptops.

• I have used iptable to restrict vnc to be accessible local only




• Are rpcbind, netbios, microsoft-ds, nfs all secured? Do I need to do something to secure them?




• How can I find out those "unknown" services? Is fuser supposed to find that out?




• I don't know if there is any program which needs to use mysql. Shall I kill the service, or restrict it locally?




• what about mysqlx?

Thanks.
