I am the only one using the computer and no one else has access to it but I am aware there is a firewall program included with Mint 13 & it's predecessors, should this firewall be set up in some way ?
Does anyone else use any sort of security program with linux apart from keeping it updated. ?
There is stacks of information about security and linux but much of it seems aimed at Business users or those with considerable knowledge of Linux so it's difficult to tell what the average home user needs, if anything .

Fedora has SELinux enabled by default to provide an extra layer of security - essentially it can stop programs and system services from doing things they're not expected to. It's supposed to "just work". I don't know if Mint or Ubuntu enable SELinux.
The Linux firewall is comparatively low level, dealing with IP addresses and ports, rather than the "Do you want to allow this program to access the Internet?" kind. You don't need to configure it unless you need to allow incoming connections to certain ports. A bit like opening some ports on a router, but without the "forwarding".

You only really need one if:-
you share the data with a M$ pc - shared folders etc
you run a mail server
You can install ClamAV and the front end for it to scan if you feel like it, or to keep to the word of the bank's instance you need an av program installed. ClamAV only runs on demand so no over head installing it.
Unless you run the pc 24/7 and have lots of programs running on it (torrents etc) there really isn't any need for a firewall other than the one in your router, that is enabled isn't it?

? Firewall in my router, I am assuming that is enabled by default, hope I am assuming correctly.
To link the router with my computer a password is needed but I also note there is a button on the router for WPS, have always left this switched off, should this be on ?

Almost certainly your firewall is switched on by default.
I suggest you play with https://www.grc.com/x/ne.dll?bh0bkyd2 - it's a site which demonstrates some internet security flaws - or lack of them.

Thanks for the link, I have used the program before but it was several years ago and could not remember the link.

In particular there is a very helpful bunch of guys in the grc.techtalk.linux group.
It's a private newsgroup, rather than usenet, but well worth joining IMHO

I don't run any firewall of anti-virus software on the netbooks. At first, I occasionally ran ClamAV but never found anything so gave up. I also ran an intrusion detection system which flagged up all the bits of linux that enables interoperability with windows so I turned them off.
I run iptables on the servers as I forward the HTTP and HTTPS ports from the router. Actually, apache 2 does a very good job of detecting and blocking access - as long as the configuration files are set for your site configuration. I use iptables to block traffic from external sites that are probing my network before it gets to apache.
The trick with linux is to only install what you need and only ever log in as a normal user. Then log into a terminal as the administrator to administer the system.

I enable ufw (uncomplicated firewall) on laptop / netbook when using public WiFi or a 3G dongle.
It has GTK and Qt front-ends as well as a CLI; you'll find Gufw in the Mint menu.
