I would like to point something out which folks may not understand, but
find a little interesting about the relationship ICSA Labs has with its
vendors (our customers):

Assume a vendor is participating in our program, and attains certification
(many do not). From that point in time, going forward until when the
product is withdrawn from the market, or the the vendor withdraws from the
program, the certified product is under ICSA Labs scrutiny and subject to

If we find (through our own investigation, or with subtle assistance like
that provided by Mikael Olssen) that the product is no longer in
compliance with certification requirements (see criteria link below), we
communicate this to the vendor and ask for configuration assistance,
assuming that we have misconfigured the product. 8-)

In the event that the product actually has a problem, the vendor is given
a formal deadline to bring the product back into compliance, or face loss
of certification.

In the past, and I have been personally involved with the firewall testing
and certification program at ICSA Labs since early 1997, this has proved
to be VERY effective. Unfortunately, this all happens "behind the
curtain" in almost every case, so the security community may not be aware
of it going on.

I would also like to point out that because we have a business
relationship with our customers, ie money changes hands, we have good,
current lines of communication with our vendors almost all of the time.

While we cannot make a blanket offer to test any and all issues reported
against any and all of our vendor's products (we juggle finite resources
like everybody else), we WILL offer to engage in a dialog with any
researcher who thinks she has found something "interesting" related to
one of our customer's products, and will offer to broker communications
between any researcher and any of our customers. said:

If is isn't already obvious, I work for ICSA Labs

Firewall Criteria:
We are currently testing against the 4.0 version of the criteria.
