PCI Compliance for Retailers from the Cloud Perspective

PCI Compliance for Retailers from the Cloud Perspective
One of the key drivers to IT security investment is compliance. Several industries are bound by various mandates that require certain transparencies and security features. They are designed to mitigate aspects of risk including maintaining the sacrosanctity of customer information, financial data and other proprietary information.
One such affected vertical is retail. No matter if you’re Wal-Mart or Nana’s Knitted Kittens, if you store customer information; if you process payments using customer’s credit cards, you are required by law to comply with a variety of security standards. Although there are several auditing agencies and mandating bodies, today we will concentrate on the one compliance agency that is typically applicable to every retailer-PCI.
PCI (Payment Card Industry) enforces Data Security Standards that looks to ensure that ALL companies that process, store or transmit credit card information maintain a secure environment. Now of course, not all merchants are created equal. Nana obviously doesn’t process the volume or the dollar amount of a national or even a high traffic regional retailer. However, this doesn’t let Nana off the hook. Her online shopping cart still needs to be Payment Application DSS validated (PCI compliant). She still is required to pass security audits of her network…just not as often.
But for the sake of this example, let’s assume you are a retailer who processes more than 20,000 transactions a year and the administrative burden of PCI is a real concern. In fact, it is a business necessity to maintain merchant accounts with VISA, American Express and MasterCard. And it is hugely important to keep the confidence of your customers. Fines for non-compliance aside, a breach of your network could cost millions of dollars. And that doesn’t begin to calculate the cost of customer defection through loss of trust.
Most, if not all, retailers have some sort of PCI monitoring in place. However, they are often cumbersome, expensive and resource heavy. Additionally, too many retail organizations don’t employ a compliance officer, much less a dedicated security person. This doesn’t mean these functions aren’t part of someone’s job description. Typically, they are yet another line item in a plethora of competing priorities and mission critical initiatives. In that security can be considered a cost center, the move to simply do the bare minimum to meet compliance is often an attractive alternative. Until now. Until the cloud. More specifically, a holistic enterprise security initiative deployed and managed from the cloud.
So how does cloud-based security/security-as-a-service meet the requirements of PCI while driving down costs, freeing up personnel resources and providing an easy-yet-comprehensive suite of capabilities and functions? The easiest way to illustrate the potential is to look at the individual PCI requirements and how they are addressed from the cloud:
1.    Protect Data: A cloud-based SIEM offering can accomplish the most important feature of this requirement: the ability to instantly recognize any change, intrusion or activity to your firewall IN REAL TIME. That’s the key. There isn’t the lag of looking at all the logs a week later when the damage has been done, or not being able to tell a suspicious action from a white noise false positive. Whereas many SIEM products can do just this, ones from the cloud provide the additional benefit of 7/24/365 monitoring across the entire enterprise. And, you get a scope of visibility of Fortune 500 class protection for literally pennies on the dollar.
