Are the services on my laptop secured?
I was cautious about the security of the services on my laptops.
I have used
iptable
to restrictvnc
to be accessible local onlyAre
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.
