Keeping Tabs on Mobile Devices

With an increasing amount of sensitve data being stored on personal devices, the value and mobility of smartphones, tablets, and laptops makes them appealing and easy targets. These simple tips wil help you be prepared in case your mobile device is stolen or misplaced

  • Encrypt sensitive information. Add a layer of protection to your files by using the built-in encryption tools included on your computer’s operating system (e.g., BitLocker or FileVault).
  • Secure those devices and backup data! Make sure that you can remotely lock or wipe each mobile device. That also means backing up data on each device in case you need to use the remote wipe function. Backups are advantageous on multiple levels. Not only will you be able to restore the information, but you’ll be able to identify and report exactly what information is at risk. (See Good Security Habits for more information).
  • Never leave your devices unattended in a public place or office. If you must leave your device in your car, place it in the truck, out of sight, before you get to your destination, and be aware that the summer heat of a parked car could damage your device.
  • Password-protect your devices. Give yourself more time to protect your data and remotely wipe your device if it is lost or stolen by enabling passwords, PINs, fingerprint scans, or other forms of authentication. (See Password Guidelines.) Do not choose options that allow your computer to remember your passwords.
  • Put that shredder to work! Make sure to shred documents with any personal, medical, financial, or other sensitive data before throwing them away.
  • Be smart about recycling or disposing of old computers and mobile devices. Properly destroy your computer’s hard drive. Use the factory reset option on your mobile devices and erase or remove SIM and SD cards.
  • Verify app permissions. Don’t forget to review an app’s specifications and privacy permissions before installing it!
  • Be cautious of public Wi-Fi hot spots. Avoid financial or other sensitive transactions while connected to public Wi-Fi hot spots.
  • Keep software up to date. If the vendor releases updates for the software operating your device, install them as soon as possible. Installing them will prevent attackers from being able to take advantage of known problems or vulnerabilities. (See Understanding Patches and Software Updates.)

What can you do if your laptop or mobile device is lost or stolen? Report the loss or theft to the appropriate authorities. These parties may include representatives from law-enforcement agencies, as well as hotel or conference staff. If your device contained sensitive institutional or student information, immediately report the loss or theft to your organization so that they can act quickly.
