How to Avoid a Mobile Device Security Breach

Mobile device security

Mobile devices have become an integral part of everyday life, storing personal and important information, including pictures, emails, apps, and financial accounts. Almost anything that can be done on a computer can now be done from a mobile device. As mobile devices become even more robust, it becomes even more critical to maintain device security.

Here are some simple steps to prevent a device security breach:

1. Use a device passcode

Periodically back up data to the iCloud or Google cloud. Data that has been backed up can easily be restored if your mobile device stops working or is accidentally wiped.

2. Be aware of using public chargers

Charge your phone only on trusted USB ports like your computer and in your car. Using USB charging ports in public places like airports, public libraries, or coffee shops could expose your private data to lurking cybercriminals.

3. Only install apps from trusted sources

Apps collect a lot of information about you such as your contact list and browsing history, so you want to make sure you verify your app source before installing.

4. Do not attempt to “jailbreak” devices

When Apple users remove software restrictions imposed on Apple products, it is referred to as jailbreaking, which lets users install applications not authorized by Apple (van der Kleut, 2019). Jailbreaking a device can enable an attacker to easily gain unauthorized access to your phone.

The additional capabilities of modern mobile devices are subject to malicious attacks by cybercriminals. Our mobile security tips, combined with staying vigilant, can help mitigate your risk. For additional information and best practices, explore the rest of our Information Security posts.
