Now that we know how to use free public Wi-Fi, let’s lock out the bad guys from your mobile devices, which contain all sorts of private, sensitive information, including photos. This data can be hacked into remotely or accessed directly if someone steals an unprotected device.
1. Customize your mobile device.
If someone grabs your device, make sure they can’t get your information. Use a custom lock screen and ambiguous application icons and names, not “Finances” and “Party Pics.” Delete default apps you don’t use.
2. Disable your GPS.
Keep your location hidden until you need it for a navigation app.
3. Don’t download unofficial versions of popular apps.
These sites are not secure.
4. Be careful with Google Maps.
If you use it, disable or don’t enter your home address.
5. Don’t stay online indefinitely.
If you’re not using the Internet, get offline.
6. Read app permissions carefully when downloading and consider whether the app really needs permission to do what it is asking.
When in doubt, don’t download.
7. Don’t save passwords in your browser.
This is convenient but not secure. Use a password manager.
8. Put a passcode on your mobile device.
Customize the lock screen if you have an Android. Use a longer passcode, not a PIN, on an iPhone.
9. Vet your apps.
Check that they don’t have personal info you don’t want to share. Read text next to the checkboxes you click when you install apps. Audit your apps monthly.
10. Never save a password for financial apps.
This includes apps for banks and anywhere you make a purchase.
11. Use cloud encryption for personal information.
Android allows this for all device data.
12. Update operating system and app software.
These often include security upgrades.
13. Use anti-theft software.
These help you locate a lost or stolen device and wipe it remotely.
14. Back up your entire device’s data.
