Data breaches are going to happen. The important part, says ACI Worldwide's Seth Ruden, is how an association chooses to handle them

Unless you’re been living under a rock in North America, it’s pretty hard to have missed news of recent high profile data breaches.

[Incident response matters]

I’d venture to say these stories have made their way into the wider, global purview (note: as I write this, another report regarding a massive data breach in South Korea affecting 20 million cardholders was released). While the number of retailers and account holders impacted by these events continues to increase and make headlines, issuers and merchants alike must address ways to instill confidence in their customers in short order.

Upon hearing this type of news, cardholders immediately think “Was I impacted? What do I need to do? Will my account be closed? Will I get a new account number and new debit or credit card?” These and many more questions likely flood the support lines as customers want to understand their real-life implications and steps they need to take to protect themselves.

When associations, banks, issuers and retailers identify significant and/or high profile data breaches, they must first identify the nature of the problem, recognize the potential impact, and then develop the correct course of action for their institution. Following this, they need to best determine how to communicate with their impacted customers.

When financial institutions have a well-coordinated strategy (i.e. email, SMS, voice, mobile app, etc.) in making their customers aware of the institution’s vigilance, posture and plan, they win. It goes beyond just reassuring a customer; it is an opportunity to assert a distinctive leadership role in the marketplace.

In instances where a mass block and reissue event is warranted, proactive communication – identifying the problem, how it’s going to impact your customer and what you’re doing to put it right – can be an opportunity to stand out as a financial institution, distinguished in your customer relationships. When a breach is made public, the ability to keep your customers informed via multiple channels can be a true differentiator in customer satisfaction and speed to response. For banks and processors who are solely evaluating high profile breaches through the lens of a risk or security response, this can be a segmentation opportunity.

An unfortunate reality of being in the payments business is fraud. Most in the industry accept that these events can and do happen. A lot. I would estimate that there were many hundreds (if not well into the thousands) of data breaches last year of varying size, some of which were never reported, some which were reported and then intentionally buried.

In fact, a recent Infosec study suggested that 57% of malware self-detected in business was not reported. Further, law enforcement believes they only have visibility to a fraction of these breaches. These incidents happen to businesses of all sizes, in many geographic locations and when you are in the trenches of fraud monitoring, these are constant issues that may require your attention. They’re exhausting and so common; recently “breach fatigue” was coined to describe the condition.

The expectation that breach fatigue is something new, however, shouldn’t be. One of the most sound things said over the last few weeks came from a sage veteran law-enforcement officer who now only consults for banks…and we’ve heard this before; the working assumption should be that all cards may already or at any time be breached, at risk and carry the potential for fraud.

Using this as a baseline assumption, and then utilizing another industry standard of layered security/controls, issuers should be able to assume the posture to manage this situation effectively. The position is this: that the financial services industry can set controls that are tied to this specific breach, as well as controls that are tied to the one that came before it and finally create controls that will protect us from the next one. Deploying a risk-based, compromise-centric and layered framework is one way to prevent data breaches from stunning us in the future.

Coupling that with a proactive customer communication management plan is paramount and elevates that framework. This combined path best positions the institution in support of its customers and against the fraudsters who are trying to exploit the system. Breaches are now quite common, but the response to them is what makes an institution uncommon in the environment.
