The real problem is that Covad claim (second hand) that they can't
identify the perpetrator(s).
I've been nudging an operator at Covad about a handful of
hosts from his DHCP pool that have been attacking -
relentlessly port scanning - our assets. I've been informed
by this individual that there's "no way" to determine which
customer had that address at the times I list in my logs -
even though these logs are sent within 48 hours of the
incidents.
One shouldn't need to have to get the indentities of the perpetrators
to get AUP enforced. Port scanning is against 99.9% of AUP's.
