Setting Up Your Defenses | Maintaining Your Defenses | Defending Mobile Devices

Mobile devices, like smartphones and mp3 players, are really like tiny computers. They can send emails, they can surf the Web, and they can get really nasty malware just like their bigger cousins. They also hold a lot of personal information that you wouldn't want in the wrong hands.

Protecting Your Mobile Device

Here are some tips for protecting not just your mobile devices but also portable computers like laptops, netbooks and tablet PCs:

  • Install anti-malware software and a firewall.
  • Don't send data over an unsecure connection - Malware and cyber criminals can lurk in Wi-Fi networks and can steal data sent through them. Don't text or email anything personal or sensitive or log in to any accounts unless you're absolutely certain the network you're using is secure.
  • Think twice about storing your log in information or password in apps - If you ever lose your device or even lend it to someone else, they can access your accounts and your personal information.
  • Take care of your device - It's like an egg, very fragile and something you don't want to sit on or drop. Unlike eggs, you shouldn't expose your mobile device to extreme heat or cold. Dirt and crumbs can really mess up the way the buttons and battery work, so be sure to keep it clean too!
  • Don't leave your computer or mobile device lying around unsupervised or bring too much attention to yourself when using it in public. If people see it, they might try to steal it.

Changing the limitations of a device so you can do something that the manufacturer didn’t want you to do. People jailbreak mobile devices so that they can change settings or download programs that are normally unavailable to them. Although it is not illegal to jailbreak a device, it usually voids your warranty, so if something happens to it, the manufacturer doesn’t have to replace it. It can also make it easier for hackers to break into your mobile device.
