The adoption rate of mobile devices continues to soar, with Android leading the way. The open-source operating system that is led by Google is now found on more than half of all smartphones. This massive user base has caught the attention of cybercriminals, who have begun to double down on their efforts to illegally obtain personal information from Android owners. While most mobile malware is found in countries like Russia and China, users from Europe and the United States aren't completely immune.
There are a few simple steps you can take to avoid getting your data locked up in an encrypted jail.
1. App source
Only download apps from trustworthy sources like the Google Play Store. Be wary of any site that allows you to download paid apps for free.
Even when downloading from the Google Play Store you need to be careful. Check the permissions the app asks for. Often, apps that include malware will ask for a lot of permissions so that they can quickly gain control of all of your phone's data.
Google includes numerous settings in the Android operating system that can prevent malicious attacks. Devices running Android 2.2 or higher, which essentially means nearly all Android devices, have access to Google's malware scanner. Prior to installing an application, you downloaded outside of the Play store, Google will scan the app and warn you of any potential threats.
4. Software updates
While this may not be an option for most users, if there is an update for your device make sure you download and install it. Manufacturers, carriers, and Google are constantly pushing out updates with bug fixes, enhancements, and new features that can make your device more secure.
5. Antivirus apps
The Google Play store is also home to hundreds of antivirus apps that can offer an extra layer of protection. Companies like Avast, AVG, BitDefender, Kaspersky, Sophos, Symantec (Norton), and TrendMicro have long and established histories as some of the most trusted brands in the industry.
6. Back up your data
Keep your device backed up. You can do this:
• On your computer.
• Using a cloud based back up service like Google Drive.
• On a portable hard disk like a USB pen drive.
