Credit Card Data
Credit card and other customer information is the most frequently targeted data type, making up 89 percent of breach data investigated by the Trustwave SpiderLabs' forensics investigators in its 2012 Global Security Report. According to the report, industries with franchises, such as the food and beverage and hotel industries, had the highest percentage of breaches. Those firms typically lacked IT teams, making satellite locations especially vulnerable, Trustwave said. Credit card data should be protected by end-to-end encryption and never be stored, according to the Payment Card Industry Data Security Standards (PCI-DSS).
