Indeed we should. It's easy to compare numbers, but that's not the real story. Almost by definition an ISP has no administrative control of the computers its customers use to connect via its service. Corporates are totally different in this regard -- in fact, diametrically opposite. Corporates own and thus are responsible for the control of all the computers they attach to their LANs and should be responsible for the actions of all those machines. So, in answer to your question, yes, we definitiely should expect more -- a great deal more. Will they be perfect? Sadly, no; partly because of human fallibility and partly because too many of them take what seems to be your view -- "controlling all this is a hopeless task so why even bother trying". And finally, I don't think SI's efforts show that any F500s are as bad as a "typical ISP". SI is, however, showing that at least some F500s have lazy arse/stupid/otherwise incompetent admins and/or oversight procedures and/or policies driving the whole mess of their IT systems, and as a result the rest of us pay for their incompetence. > Also, as a side note, I would like to add that just because SPAM is coming > from a certain gateway does not necessarily mean that the machines on > their network are infected. ... Did you read any of their reports fully? They don't assume that. They track the mail back "behind" the gateways and they know what forms of what spam are being sent through bot-nets because of other systems they run (honeypots, etc) and analysis they perform. > ...
