Over 90 Percent Of Companies Regularly Expose Data

Employee and customer data is exposed, and potentially within the reach of hackers, at a whopping 91 percent of companies monitored by a security firm.

According to the second monthly Insider Threat Index generated by Reconnex, a Mountain View, Calif.-based enterprise risk management vendor, 91 percent of the companies undergoing assessment in July exposed credit card numbers, and 82 percent exposed employee Social Security numbers.

"The origin of the vast majority of these disclosures stemmed from human resources departments," said Reconnex's July index report. "[These departments] often accidentally exposed employees' personal information when they communicate with partners in health insurance, payroll, workers compensation, and other third-party processors."

In other cases, claimed Reconnex, employees are exposing data by sending files using Web e-mail services such as Hotmail and Yahoo Mail.
