RE: MasterCard backs off Security, Leave Cardholders at Risk

["Craig Wright" <cwright () bdosyd com au>]

There are levels to the PCI. The high volume clients have to be tested
in depth. Most have only a simple test.

Correct me if I'm wrong, but there is no such thing in PCI
as "a full scale in depth web application test", as nice
as that sounds.

IIRC, it's a generic BITS/Roundtable type checklist, "do
you have passwords" kind of stuff.

One of the checklist items is "was an assessment performed
that evaluated [insert OWASP Top-10]". Another checklist
item was "are a [smattering] of [software developer types]
trained on the [insert OWASP Top-10]?"

This is due diligence. Not a bad thing, to be true, but
how is a checklist auditor going to know if the group that
assessed the application knew how to test for blind SQL
Injection, and timing-based inference (SQL Injection or
otherwise), let alone buffer overflows, properly encoded
XSS/script strings, or if they just clicked "scan"?

That's a huge difference, and far from leaving me with
a warm fuzzy. I've seen such a huge variance in reports
from vendors performing webappsec assessments it's shocking
(or maybe not); at least two were worse than if they'd
just gotten a commercial webapp scanner and clicked "scan".

However, it's a start. To be sure. Gotta start somewhere.
