hi,

i am new to ubuntu and would like to know about security programs in general.
in windows, a firewall and a real-time residential antivirus is recommended. is this also the case in ubuntu 8.04 hardy heron? we already have firestarter as a firewall and clamav as an antivirus, but don't know how to verify if they are serving their function.
can other av's be installed and ran as on-demand scanners without conflict? how is this done? newbie-newbies here.

Firestarter is pretty much dead now, but i have heard
it is a good app for firewalling. I tried it and had problems
so i went back to Shorewall.
As for AV, you really don't need a resident (real-time) scanner.
Some like clam and vexira are real-time in the sense that they
scan incoming email. They do not offer protection from downloads.
For on-demand scanning I use BitDefender. I have tried AVG for Linux
and while it offers a GUI for easy scanning it did not detect some files
that BitDefender did. See the results here:

raw,
it is evident to me that i am wasting my time using an antivirus. i need to be focused on the firewall. i did a "shields up" and "leak" test yesterday and let's say it's "not secure".
if you have any insight about the firestarter program (i think it's iptable that is the actual firewall) please indulge me. i don't think i have it configured properly. i don't remember installing iptables at all.
thanks for the reply.

What exactly did Shields-Up report? Are you behind a router?
Firestarter is just a GUI for configuring "iptables" which is installed
by default. Here is a link to the Firestarter guide, hope it helps.

Personally I do not agree that AV is a waste of time. While it's true
that virii and other malware are coded for Windows, we are likely to
start seeing new malware targeting Linux. Never hurts to run an
occasional scan even if just for that "my system is clean" feeling.
