The number of personal mobile devices connecting to the corporate network has more than doubled in the past two years — with nearly half of devices storing sensitive data.

The report, The Impact of Mobile Devices on Information Security, shows 71 percent of businesses believe mobile devices have caused an increase in security incidents, citing significant concerns about the loss and privacy of sensitive information stored on employee devices, including corporate email (79%), customer data (47%) and network login credentials (38%).

Smartphones and tablet PCs continue to proliferate in corporate environments, presenting significant business benefits such as increased work efficiency and easy access to resources. While businesses are steadily accepting this trend, IT administrators struggle with securing the abundance of devices and operating systems, while also protecting their organization against data loss and the rise in mobile threats.

“The consumerization of IT is among the top concerns for CIOs this coming year and we wanted to assess from IT administrators the current security challenges they face when it comes to mobile computing,” said Juliette Sultan, head of global marketing at Check Point Software Technologies.

“The explosion of mobile devices connecting to the corporate network often creates greater opportunities for data loss and increased security management complexity. We anticipate this trend will continue to rise in 2012, encouraging enterprises to enforce the proper remote access policies to minimize the frequency, risk and costs associated with securing the mobile enterprise.”
