The holiday season is the busiest shopping time of the year. Shoppers are forking over money and retailers know they need to be at the top of their game to make sure they don't miss a single sale. However, criminals are also aware of the fact that the greenbacks are flowing and merchants need to make sure their entire point of sale process is secure.

Regardless of what your organization does, security is key. According to a statement released by the company, Target is the latest victim of a breach. Between November 27 and December 15 2013, approximately 40 million credit and debit card accounts were impacted. Criminals were able to steal customer names, card numbers, expiration dates and CVV codes.

The exact nature of the breach is still unknown, and the company is currently working with a third-party forensics firm to investigate the incident and strengthen its overall credit card processing system.

"Target's first priority is preserving the trust of our guests and we have moved swiftly to address this issue, so guests can shop with confidence. We regret any inconvenience this may cause," said Gregg Steinhafel, Target's chairman, president and chief executive officer, in a statement. "We take this matter very seriously and are working with law enforcement to bring those responsible to justice."

Target is just another example of a company having its customer credit information stolen because of a cyber security breach. Merchants need to be aware of how the changing landscape of the cash register is effecting the levels of security that businesses require.
