The winter holidays offer big potential for retailers, with some companies earning around 30 percent of their annual revenue during the season, according to the National Retail Federation. Big sales numbers, however, also drive increased risks of fraud and theft, and businesses are now spending on extra security measures to keep physical stores safe.

But this is only half the battle. With retail stores moving online and hiring seasonal staff to bridge the holiday gap — not to mention handling employees who are more focused on holiday breaks than network breaches — it’s worth taking stock of retail security hygiene and revisiting how to protect consumer data from opportunistic cybercriminals.
