Trojans do not attack from the internet, they attack from the inside.
I greenied Jinxy for this post because you will have to forgive me if I sound like I'm spontaneously channelling the spirit of Catch, but post after post after post I've seen in my brief time here the advocation of firewalls as a pancea without a concomitant education programme on drilling in to users to adopt secure practices i.e. do NOT open or run attachments/executables unless you can verify the source as trustworthy and have scanned the attachment/executable through your AV software.

We can tell users to slap up a firewall, run AV software, yada yada yada, till we are blue in the face but it will not have any effect unless we continually remind users to educate themselves on the purpose and role of AV's, firewalls, IDS's, Routers, etc, as well as how to adopt best practice in ensuring that they operate using secure principles, or at least keeping these principles in mind.

Please forgive my Steve Gibson haranguing, but I think it is of the utmost importance to educate users like comp_custom (and myself, for that matter) on not what to do i.e. install a firewall, run AV etc, but why i.e. you need to install a firewall because of x and y, but not of z, for which you need AV to deal with. Then once suitably armed with basic information, they can then peruse these forums to educate themselves in greater detail.

This post was not directed at anyone as there is some useful and educational advice contained here, but ... Jesus! Doesn't anyone feel a stab of existential angst, a sense of Groundhog Day and that feeling, 'Here we go again ..' when a user has installed a firewall (phew) but gives the impression of opening up attachments without any thought whatsoever to their source? Apologies comp_custom if I sound like I'm flamming you (or anyone else, I'm not) but I'm worried that we've all been brain-washed into thinking that a firewall, AV, etc allows us to adopt bad practices without consequence.

That's it. I'm finished now :P
