Guest View Columnist David Taylor points out that PCI compliance has consistently generated larger security budgets, with little or no requirement for justifying them, other than “our bank told us we have to do it.” But with some acquirers being no better off financially than many retailers, it’s time to ask some hard questions: Is the risk of a security breach great enough to risk the financial health of our company?

Couldn’t rationality be achieved more easily if PCI were to mandate a specific encryption protocol at a specific point in the transaction, and equally mandating the acquirers to hold up their end of the protocol?
Place the encryption requirement (and keys) in the PCI PED approved device, and then DSS can be reduced to proper handling of the PEDs. That’s it. The data is encrypted before it gets into the merchant’s systems, and remains encrypted while passing through them. The merchants would then be relieved of the entire burden of securing their networks, and would stop being the target of attacks by hackers.
Verifone already has such a device available that Evan reported on a few months ago here: http://storefrontbacktalk.com/story/040408swipe
Today’s problems are caused because securing systems is left entirely up to the merchants. Few retailers have enough CISSPs on staff to inspect and secure every intermediate system, let alone the authority. And we certainly don’t want to pay for them all. But true securing of systems requires that depth and application of knowledge, and on an ongoing basis — anything less and you get an ad hoc collection of systems protected to varying degrees, any one of which might be subjected to an attack.
Instead, remove all those requirements from the merchants. Make it simple: merchants must buy and use a secure device from an approved vendor in order to use the network’s cards. And a member bank must buy and use an approved decryption appliance in order to participate in the network.
I know I sound like a broken record, but it’s true: if you remove the value of the information that the merchants handle, the merchants stop being the point of weakness.
