I suspect that we will see demand for DNSSEC the first time that a bank
sees a poisoning attack and their customers get redirected to a fake
site and their accounts drained as a result. Phishing attacks can be
alleviated since you can tell technologically that the site is not what
it claims. Their customers will demand it, the bank will be afraid not
to do it, the insurance companies make it a condition of coverage of
losses, etc. Then of course the military have a need for it. Of course
that still leaves the issue of validating resolvers being not being
widely deployed (okay, so only a handful of people have deployed them).
That means that Microsoft needs to implement and deploy them as fast as
possible, since they will have, by far, the biggest affect on making
this happen. They are not the only ones of course but it will have the
biggest impact. So where does Microsoft stand in all of this?
