Any employee-owned devices that are not sanctioned by the employer are known as shadow IT, and these pose a security threat to the organization. Devices not visible to stakeholders cannot be monitored or protected from malware and other security risks. Therefore, a strong device policy will identify which personal devices may be used for work as well as when employees should rely on company-owned assets.
Another risk of BYOD is the fact that employees will bring their devices with them everywhere. While it's unlikely people will carry their work laptop with them on a night out, they will definitely bring their personal smartphone. This increases the risk that a device with company data could be lost or stolen.
All of these concerns can be prevented and planned for, but it requires the employer to take precautionary steps ahead of time. Corporate policy should outline contingency plans for reducing risk and reacting to data breaches as they occur. Making it clear to employees what their responsibilities are will help them understand how to leverage their personal devices for business purposes.
BYOD policy is best implemented when company stakeholders understand the pain points they’re addressing. Stakeholders should build a security policy around the problem, then work with employees to implement the solution in a mutually beneficial manner.
