ISPs have had a rough day of it on the first day of Infosec.

No-one's had a good word to say about them on the floor of the show and it’s difficult not to see the point – we seem to accept quality of service from ISPs that we’d be up in arms about with any other utility.

A good credit card company calls you if your bills suddenly “show red” after large purchases are made. It’s a safe bet that if a home computer is sending hundreds of emails a day that’s something going on so why are ISPs abdicating their responsibility. 

There are technical fixes available to stop many security problems and the ISPs are missing a massive opportunity by not acting sooner. There’s a lot of residential and business users who would pay a little extra for a clean internet service and with a few million users that adds up to a lot.
