Mmmm read the article and although it seems well intentioned, is a little naive. What happened if I wanted to send a .pif,exe,bat or scr with no intent of harm?
Another problem then arises, what I call the Volvo (or US the SUV) syndrome. They make them bigger and safer and as a result, the owners decide they no longer need to indicate, stay in lane or bother to take care at junctions, becuase as they see it, their car is safe, so there is no need.
Look at it this way, if the users belive that all virus and worm threats are done by the ISP then they will open everything,because everything has been scanned hasn't it?
As a major company, we tend to get hit by viruses within seconds of them going live. More often than not firewalls, mailsweepers etc pick them up, but sometimes, the attack is so new and quick, that there are no detection facilities availible, so we have to rely on some common sense on the users behalf.
What is needed is a balanced approach, which involves everyone.
Microsoft are doing there bit making the firewall on by default in XP sp2 and releasing patches.
Companes and end users need to practise caution in opening attachments. Our company has a simple attitude to these problems. We force their pc off the network and inform their manager of the situation. We then make them wait for us to fix it.
ISPs can do more, maybe scan for Viruses, but not block harmless files. I'd say more important than this, is look for machines that are scanning networks (either port scanning or pinging) and block their access untill they supply the isp with a good reason for doing it.Maybe go as far as saying that you are no allowed to have access until you have a firewall and even some form of av in place. It would cost them much to supply these as part of the package the give you when joining. After all many worms now no longer rely on someone opening an attachment.
