Does anyone have a contact at Brentwood, TN-based Secure Identity
Systems?  They just issued a press release touting their new
anti-phishing services
F4-B130-57BF8F55D698}&siteid=nbkh), and might have useful data for this

        Secure Identity Systems is the leading provider of managed,
total identity theft protection systems that safeguard  financial
institutions, businesses, individuals, and households.  SIS'
anti-phishing services enable banks, credit     unions, and other
financial organizations to track the occurrence of their name, brands,
trademarks, and slogans on      the Internet.  

        The service identifies phishing attacks, where e-mails and Web
sites that display the financial        institution's   brand are used
to trick unwary consumers into providing account and logon information.
The technology uses     extensive Internet surveying, which works by
comparing the authentic Web site with a continuously updated database
that includes over 172 million Web sites and domain names, SSL
certificates, and feeds of phishing data from   multiple sources.
That's only the beginning: after a phishing site is detected,
countermeasures are launched to         take down the phishing site.
First, access to the site is restricted in popular browsers and security
products,       reducing its ability to lure and entrap consumers.  The
service then contacts the site owner, the ISP responsible       for
hosting the site, the domain registrar, upstream provider, and law
enforcement to have the phishing site taken     down.  Once a site is
taken down, the service will continue to monitor the site from various
monitoring points       around the world.

services, please visit www.secureidentitysystems.com    or call

Many thanks to Joe St Sauver for putting me in touch with Jose Nazario
of Arbor Networks.  "Arbor Networks is a leading provider of secure
service control solutions for global networks. Arbor's customers include
over 70 percent of the world's ISPs and many large enterprises. By
providing unmatched network-wide visibility, Arbor solutions deliver
best-in-class network security, traffic management, network monitoring,
bandwidth management and broadband service optimization " (from their
web site).

Jose has offered to help us out on the fact-gathering front.  here's his
email, responding to some very general questions that I just posed to
him.  I wanted to share this with the group as a great 
example of a helpful partnership and resource.   Many thanks Jose!

I asked Jose whether these numbers are a good representation of the
total numbers, or are they sub-totals (based on the networks that 
they're monitoring).   He says it's independent of their sensors.  He 
goes on to say that they get candidate domains from an internal spam
feed, malcode URLs and a few blacklists.  They screen for "fluxy" 
characteristics and then track the live ones.

Here's a presentation to FIRST (last month) that he shared with me.  I
found it very interesting, all the way from data-presented to issues
that we're charged with looking into.  Worth the read IMHO;


Here's his email response to my broadly-framed questions (I promised him
that our questions would get more carefully-crafted);
