Without a bring your own device policy in place, companies will often struggle to keep a handle on all the devices using the corporate network. A recent report by Blue Coat found that even after implementation, employees and the IT department don't exactly see eye to eye on BYOD, according to CIO.com.

Numbers from the report, according to the news source, showed:

- 83 percent of companies allow employees to use BYOD for email and 56 percent for instant messaging, but other apps are used more sparingly
- 77 percent of IT managers think there is a risk of malware spreading into the corporate network via these mobile devices
- Only 24 percent of employees are willing to let IT log corporate data access from personal mobile devices and even less (19 percent) said they'd be willing to let the IT department log any web content from personal devices

"People who are accessing these corporate networks are being logged and they don't realize it," Timothy Chiu, director of product marketing at Blue Coat, told CIO.com. "And the regulations have come down pretty clear on this: The corporate network is a corporate-owned resource and companies are allowed to log what they want."

TechTarget said two keys to forming a great bring your own device policy on a business level are asking the right questions about how the network will be monitored and what limitations there are. Businesses should also be assessing how mobile employees will be using the network, to figure out where holes in coverage may exist.
