Use well-known networks, if you must connect.
Try to use as few public networks as possible. In a pinch, when looking for Wi-Fi to connect to, stick to more well-known networks. These would be found at popular restaurants, hotels and stores you may be visiting or near, and will be less likely to be operated by bad actors. While no public network is 100% secure (especially those that aren't password protected), they will generally be more reliable than a network operated by someone you've never heard of.
Also, be on the lookout for fake networks. A key thing to watch out for is the misspelling of a common network name. Keep your eyes open for suspicious signs, like an interface not matching the branding of the location, or the access point asking you for a lot of personal information to join. If something seems fishy, don’t join the network or exit from it right away.
Turn off file sharing and Wi-Fi when you’re not using the internet.
Some devices like laptops have a file sharing option. This allows people to share files and see each other’s files when they're on the same network. Make sure you disable this feature if you don't need to use it. That way, if you connect to a public network, you'll be able to control what your device is sharing.
Also, keep your devices in airplane mode and/or turn off the Wi-Fi function when you are not using them. Your cell phone may be set to automatically join networks, so turning off Wi-Fi will make sure you have control over which networks you join.
Look for HTTPS.
Don’t access sensitive data on public networks.
Buy a data plan or use a VPN.
If you are traveling internationally, consider checking in with your mobile carrier to see what options you have. Many plans include data usage in certain countries, which allows you to use your cellular data without extra cost. There are also additional plans you can purchase that provide limited data usage for when you can’t connect to a secure Wi-Fi or have an emergency.
You can also consider purchasing a virtual private network, or VPN. A VPN is essentially a private connection between your device and the websites you visit. It adds an extra layer of security that encrypts your data. When selecting a VPN, make sure you know how many devices can be used, that it works in the countries you'll be visiting, and that you understand the limitations and costs associated with the purchase. You can find many options by searching your mobile app store for a VPN.

Prep for your trip.
Before you leave, add a tech check to your to-do list. Make sure your computer, cell phones and tablets are in tip-top shape with the latest software updates, including your security software. Having the latest technology updates will give you a fighting chance if a hacker attempts to gain access to your hardware.
Also, if you haven’t updated your passwords in a while, now is a great time to do so. See our article on creating a strong password for advice on how to get started.
If you know you'll have to send banking or credit card info over the internet while traveling, consider contacting your bank and credit card companies to see if there are limits you can put on spending. In addition, many of those companies can help you set up alerts that will notify you when accounts are used in suspicious ways, so you'll be able to take action if needed.
