Question What are the best ways to secure Ubuntu on a laptop?

I loaded Ubuntu on a Windows OS laptop and am finally figuring out how to connect wireless. Before I do what can I do that will protect me?
I am told I don't need anti-virus. Is this accurate?
Also, I want a really secure firewall...not one that an experienced hacker could see and just hop over.

Any help appreciated, thanks.

You really don't need to do anything aside from making sure the system is up to date (Ubuntu automatically checks for updates by default).

There is a firewall included, but it isn't enabled by default. If you want to turn it on, check out the Ubuntu documentation for ufw.

Encrypt the drive
use a ssh tunnel or vpn
Make sure you keep Ubuntu update including browsers and plugins
Install and use rkhunter, chkrootkit, tripwire


Securing Debian Manual :
written for Debian but most of the info applies equally to Ubuntu

I'd start with trying live cd's. Wireless may be an issue for a newbie maybe. A lot of words are different in linux but the though is similar. May have to play with it for a while.
