Even if a lower-ranking employee loses a device, problems can arise, Mullen noted. That employee may have information stored on the device including contacts, photos, call history, and notes and personal information about contacts.

If the employee works in the healthcare field, theft of such information could trigger Health Insurance Portability and Accountability Act (HIPAA) violations, Mullen said.

Mullen pointed to another emerging risk tied to mobile devices: a “bring your own device” philosophy developing at many companies. He says there are some advantages to such a policy, such as cost savings if employees are spending their own money on smartphones and tablets that are constantly evolving and being updated.

However, he said such a policy can raise questions regarding who owns the data on the phone when company data is mixed with personal data. For example, Mullen asked if the company would have the authority to wipe the information from the phone when the employee leaves the company.

Mullen said that if an employee connects a personal device to a company network, the company just inherited responsibility for that device.

Despite the risks, though, Catherine Mulligan, senior vice president at Zurich NA, said that in an age where employees take advantage of 24/7 connectivity, a mix of personal and company information on personal devices “feels pretty inevitable.”

In order to address the risks around mobile devices, the webinar panel said companies must enact comprehensive risk-management plans that include training employees on how to respond if a device is lost or stolen.

Mulligan said C-suite executives and risk managers cannot assume that IT departments will be responsible for all security measures. Plans have to be enterprise-wide, she said. Risk management, she explained, starts with IT controls such as VPN (virtual private network) usage, encryption, and having a plan to track down lost devices and react.

But beyond the IT department, employees should know who to call if a device is lost or stolen, and the person the employee calls should know what to do once notified, said Mulligan. She said companies should provide regular training in which all employees using personal devices must participate on annual basis.

Mullen added that response to a lost device can become “surprisingly simple” if a company has the proper procedures in place.

Mulligan said insurance for devices is also available. Coverage, she said, is not much different for mobile devices than for any other type of data breach. She said there is liability coverage that deals with legal costs and third-party expertise such as forensics firms to analyze a breach and call centers to provide information and public relations. Coverage also may include services, such as access to tools to estimate costs, a checklist for a company's planned response, and access to experts who can answer questions and review a company's policies and procedures.
