With a bring your own device policy, protecting data must be the first and last thing a company thinks about, according to one expert. Jack E. Gold, principal analyst at J. Gold Associates, said that this is the biggest challenge companies face, so businesses may want to look at endpoint security and mobile device management to get more leverage in their security solutions.

"Employees usually are not very concerned about securing company data; instead, they complain when the corporation puts safeguards in place that interfere with how they work," Gold explained, saying this can cause some problems, including employees visiting websites infected by malware that can expose a system to hackers looking to steal data.

Enterprises need to know which operating systems they need to protect, and Gartner said Android seems to be looming larger. Gartner anticipates there being more than 1 billion open operating system devices sold by 2015, accounting for 47 percent of the market, so companies should start thinking about securing these devices better.

Gold told Network Computing that companies should have mobile device management or other security programs in place to make sure they can monitor and keep up with security. This can allow companies to wipe any stolen or missing devices if need be, among other features.
