"Who's to say a retailer doesn't take what we say and toss it into the garbage?" says Barbara Mitchell, manager of security product marketing at Verizon. Along with Internet Security Systems and TrustWave, Verizon wins much of the assessment business for Level 1 merchants. "We should have some skin in the game, but if a retailer decides to not listen to our recommendations, it's a murky area," Mitchell says. "If we assume liability, we want to review all the stores, all the servers. That shoots the cost up to a prohibitive degree."
Retailers we spoke with were unclear about the liability question. "I think it would depend on whether our controls were deficient and on the audit process," says the network architect at the major clothing retailer. "I think there would be some level of liability, but we've not dug into that. There may be language in the contract I'm unaware of, but my focus has been on controls to prevent a breach rather than where we will point a finger." Unfortunately, finger-pointing is inevitable if credit card data gets stolen. "When a breach happens, if they see something out of whack, they will go back to the auditor, like Enron and Arthur Andersen," says Teri Quinn-Andry, product marketing manager for Cisco Security Solutions.
Then there's the problem of depending on what is, essentially, an honor system for Level 2, 3, and 4 merchants. There is no outside validation of a company's responses to the self-assessment questionnaire. "The reality is, you don't have to be compliant, if your business wants to take that risk," says the IT director of a Level 2 cruise ship operator.
"A lot with PCI is left to your interpretation," agrees Alan Stukalsky, CIO of Church's Chicken restaurant chain, also a Level 2 merchant.
