Mobile Computing Security: Keep Business Data Off the Device
Mobile computing lets people use company data in the office, at home and on the road. It also means devices get lost, stolen or shared. The safest approach is to keep business data on a central server and treat the device as a window onto it. This guide explains how that works and which controls to add.
Key takeaways
- With mobile computing, the main risk is business data stored on a device that can be lost.
- Keeping data on a central server limits the damage if a device disappears.
- Device management lets you lock, wipe and update devices remotely.
- Secure networks, strong sign-in and app control complete the picture.
The risk when data lives on the device
When files sit only on a laptop or tablet, losing the device means losing the data and possibly exposing it. A stand-alone computer holds its own copy, and nobody else can recover it. For how mobile devices fit into work more broadly, see how mobile computing works.
Keeping data on the server, not in the pocket
In a central model, the device runs an app or a session, while records stay on a managed server. Staff still see and update information, but little is stored locally. If the device is lost, the data is not. The server also holds the backups, so a broken device does not mean lost work.
Controls for lost, stolen or shared devices
Add a few controls to every device: a screen lock, encryption, remote lock and wipe, and a record of who holds which device. Mobility management tools apply these settings across the fleet; read enterprise mobility management for how that works. Shared devices on a shift should use individual sign-ins so actions are traceable.
Network and app safeguards
Use secure Wi-Fi and a VPN for connections away from the office, and approve the apps allowed on company devices. Update devices regularly, since old software is a common weakness. Teach staff to report a lost device at once so it can be locked.

Mobile computing security: common questions
What is mobile computing?
It is using computing devices such as phones, tablets and laptops while away from a fixed desk.
Why keep data on a server?
If a device is lost or stolen, the business data is not on it, so the loss is smaller.
Can I wipe a lost device?
Yes, if it is enrolled in a device management tool that supports remote lock and wipe.
Do personal devices need these controls too?
If staff use personal devices for work, apply the same protection to the work data on them.
