When traveling, electronics security is very important. Some tips:
Use secure Wi-Fi. Be wary of public Wi-Fi. They are unsecured connections and you run the risk of having your personal information tracked or collected when browsing on unknown networks. Be especially careful when entering passwords or accessing personal and financial information online. Avoid public computers when possible too.
Use VPN (Virtual Private Network) when you can.
Disable Wi-Fi, GPS, and Bluetooth. Disable these functions and unused apps on your device when not in use. These services can be used to potentially launch attacks against your device, and can be used to locate and introduce malware.
Keep your devices safe. Small devices such as cell phones, laptops, hard drives, or flash drives, and tablets are susceptible to theft or loss, especially while traveling. When unattended, keep your devices secure or locked up. Create unique passwords or passcodes for each of your devices. Enable two-factor authentication (2FA) when you can.
Travel with less data. Be sure your laptop and drives are encrypted before you go away.
Make data and device backups before you go on your trip.
Have a plan in the event you do have a loss of some sort.
When you return, change all your passwords/passcodes.
