PCI Gurus?

Hello,

Regarding to your problem, let me introduce you how the PCI DSS works.
First, the PCI DSS requires that all systems, including those that are
not par of the company but are connected to it's network should be
compliant with PCI. therefore, if in this scenario company a us
installing a device in company b, the dvice and services provided by
this dvice should be compliant too. So here is the big question,
should company a be PCI compliant or just the devices? Or what
specific things from the device.
If company a installs the device and also manages it, then company a
should comply with  PCI requirements 2, 4, 5 (if applicable), 6, 7, 8
and parially 10, 11 and 12.
If company a just installs the device but company b manage it, then
company b should add some caveats to the contract with company b
detailing that and then determine the responsibility on the device

Regards,

Daniel

Heres a little scenario that I wanted to throw out there and get an opinion on by someone who knows PCI. I am 
starting to learn but couldn't help with this problem because I've never assisted in a PCI audit...

(I would think this problem has been encountered by many small companies that make network appliances)

====== Background =======

1) Company A is a small company (only 5 employees)

2) They provide a service which requires their customer, Company B, to install a small network appliance on their LAN 
in order to collect data from their onsite mechanical equipment.

3) Operating data is then pulled from these mechanical systems and then dumped to a remote server which processes the 
data and provides a dashboard for the customer to view (via SSL).

4) Company B bought a license for this service and was also handed over the keys to administer accounts and decide 
which employees it would like to give access to.

5) Now let’s say that Company B typically processes credit card payments locally and sends transaction data through 
their local LAN on its way out to their payment processor.

====== Problems =======

1) Company A does not take credit cards and is not required to be PCI compliant however they do provide a service 
which requires their network appliance to be installed on Company B’s network.

2) In recent days Company A has come to the conclusion that in some of Company B’s newly acquired satellite offices, 
credit card data is being forwarded across the LAN in a variety of ways (some of which do not look to be 
secure/encrypted).

3) In addition, several of these satellite offices are running consumer grade routers (ie: Linksys, Netgear) 
providing little in the way of segmentation.

4)Company A would like to avoid being “In Scope” and having to charge the client for consulting fees.

====== Questions =======

1) For the smaller satellite offices what might be a simple fix?

2) Does segregation provide an easy way to kick devices out of scope for PCI audits?

3) Would it be recommended/possible to have a firm produce a report which could be handed to an auditor and prove 
“Out of Scope” prior to being dragged into one of these audits?

4) Could the network appliance be designed/situated in such a way as to be “out of scope” or at least easily 
verifiable as compliant even if it was sitting on the same logical subnet where the card data traffic was moving 
across?
