Hello,
I am planning to install ubuntu 12.04 on my laptop. What I usually do for security is to lock the root account, edit the file /etc/hosts.deny and add the line ALL: ALL , set up a firewall (ufw/Gufw in this case) with default rules of Incoming:Deny, Outgoing:Allow. Is this enough for providing reasonable security for my laptop? If you have ideas about what else I can do to secure the planned ubuntu 12.04 installation on my laptop, please let me know.
