Back up your files so that you have a copy in case your device is stolen or infected with a virus.
Update your devices with the latest security software.
Use strong passcodes. A strong password should be at least eight characters long, include a combination of upper and lower case letters and at least one number, and include at least one character that is not a number or letter.
Protect Yourself While Travelling
Wi-Fi hotspots sure are convenient but they are also often unsecure networks and available to anyone. Don't shop or bank online using a Wi-Fi hotspot, and be very careful about what you send and receive.
Don't leave devices unsecured in your hotel room. If there's a hotel room safe, use it.
Avoid charging your phone at public charging kiosks or using USB ports on devices you don't own. These are untrusted devices and could leave you open to malicious software.
If flying to your destination, do not pack your devices into luggage you're going to check; instead put it in your carry-on luggage.
Be aware of your surroundings. Always assume others can view your screen or keyboard in public areas; shield passwords when entering and log out of any account.
