What are the disadvantages of employee use of mobile systems at work?

What will be an ideal response?

Employee use of mobile devices has significant disadvantages. First, there is the real danger of lost or damaged data. When data is brought into employee-owned computing devices, the organization loses control over where it goes or what happens to it. Also, if an employee loses his or her device, the data goes with it, and when employees leave the organization, the data on their personal devices needs to be deleted somehow. The disadvantages are data loss or damage, loss of control, compatibility problems, risk of infection, and greater support costs.
