Experts, vendors search for PCI’s holy grail

The First Data-RSA partnership is pitted against the Heartland-Voltage E3 project in the payment industry race for securing transactions.

Like the Betamax vs. VHS format war or the Blu-ray vs. HD DVD scuffle, the transaction processors in the payment industry are wrestling with how to secure credit card data without affecting transaction times or strapping merchants with additional costs. So far there are two options on the table: Format-preserving encryption vs. in-motion encryption and token technology.

In June, Heartland Payment Systems Inc. announced that it would work with Voltage Security Inc. and others to design a credit card masking service called E3 that uses format-preserving encryption. Heartland CEO Robert Carr briefly mentioned the E3 project at a Sept. 17 Senate panel hearing on his company’s breach. He told the Senate Homeland Security and Governmental Affairs Committee that the goal is to make credit card data unreadable to outsiders at the point of the swipe.

Another processor is working toward the same goal. Last week, while payment industry experts met at the Mandalay Bay Resort and Casino in Las Vegas for the Payment Card Industry Security Standards Council North American Community Meeting, First Data Corp. made a broad announcement, telling the industry that it planned to take a different route. First Data said it would partner with RSA to use its tokenization technology and provide end-to-end encryption and tokenization for merchants.

Which method will win the industry’s favor is anybody’s guess. But it’s likely to be a combination of the two. First Data hasn’t provided the cost of its service, but claims it won’t slow transaction times by issuing tokens. The First Data implementation should be fairly easy for merchants. Most of the work will take place on First Data’s servers. The Heartland E3 service consists of new payment terminals. Beyond the costs associated with buying and deploying the terminals, Heartland says there would be no monthly encryption maintenance fees, no key management fees, and no activation fees. Heartland has a good website describing the E3 project and its status.

Experts largely agree that these offerings are a step in the right direction to better protect sensitive payment data. Our site experts have written extensively about tokenization. Tokenization technology is a cheaper way to comply with PCI DSS, but by no means is it a silver bullet. Experts say it helps scale down the scope of a PCI assessment by making network segmentation easier. Expert Mike Chapple explained how to implement a PCI network segmentation.

One of our best pieces of advice came last year from a former certified PCI quality security assessor (QSA). He said merchants should focus on eliminating data, not securing it. The faster the data is purged from a merchant’s systems, the less likely it will have to deal with a costly data breach.

Until a solution is embraced by the entire payment industry, attackers will continue to find holes that give them access to those coveted credit card numbers. For now, we’ll have to take a step back until a method is found that satisfies both merchants and payment processors. Maybe the winning solution hasn’t been invented yet.

CISOs seek frugal ways to secure systems

It is budget cutting time. Companies in all industries are looking for ways to save money in a down economy. Security analysts say companies are slowing ongoing projects and delaying others signaling the acceptance of more risk.

Security pros that attended the two day SecureWorld Expo on March 25-26 in Boston learned about a number of ways to keep sensitive systems locked down while trimming their already tightening budgets.

Candy Alexander, CISO at Long Term Care Partners LLC, urged attendees of her session, “Security compliance program on a shoe string budget,” to develop a framework by using guidelines outlined by NIST. Alexander said NIST would be a cheaper source over the ISO standard. Although the benefits of ISO over NIST or vise versa is debatable, ISO is also not a widely adopted standard in the U.S., she said.

While much of the information doled out during the 45 minute presentation was basic, it certainly could serve as a starting point for some security pros looking for ways to keep systems secure despite a tightening budget. The most important piece of the talk: Know your data. Know where it is. Know how it flows through your systems. It’s so simple, yet time after time I hear that many data breaches happen because an attacker found a hole in a database that IT didn’t even know existed.

A friend who works for a major university in Massachusetts told me that in the first few weeks on the job he followed the basic steps of identifying the most sensitive information, where it was and how well it was protected. During the process he found a database containing thousands of credit card transactions in a small office off one of the university’s dining facilities. It had been there for years. Few knew it was there and those that did — dining facility staff with little technical expertise — didn’t realize the data residing on it was so sensitive.

Having a sound security policy and enforcing that policy was also one of the takeaways from the expo. Although it’s another fundamental part of being a security professional, we’ve heard countless times that some organizations have policies that they downloaded off of a website and rarely refer to them or educate end users about them. Charles Cresson Wood, a consultant at InfoSecurity Infrastructure Inc., a Mendocino, Calif-based consultancy, gave the SecureWorld keynote, urging those listening to rethink their security policies. If an organization doesn’t have policies that align with business objectives then they should be written with that in mind, Wood said.

Wood advised attendees to conduct an annual risk assessment tying it into the company security policies. He said some of the best security programs also create an environment that fosters higher security standards among employees. Management plays a big role, he said.

Finally, an information security officer tag team of Leilani Lauger of Loyola University and Morey Straus of NHHEAF Network Organizations tackled ways CISOs can do their job frugally. Straus said CISOs can consider managed security services and should also take a look at the company’s existing contracts with third-party vendors. Some of them may be able to be renegotiated at a cost savings, he said. Straus said CISOs can also help foster the culture of valuing information security by acting “less as a cop and more like a guide.” Lauger said security pros should also design training programs that are interesting and replace outdated posters and material with fresh content on a regular basis. Send out security messages in multiple forms, not just weekly email messages or security posters, she said.
