Security tips for public Wi-Fi networks

Published

Today there are many public places that offer free Wi-Fi connections, such as trains, shopping centers, stations, or cafes. We explain the dangers of using them and how you should protect yourself.

The free Wi-Fi connections that you can find in public places offer us a practical way to connect to the network without having to consume data from our operator’s data plan. Sometimes it is the only alternative for your laptop or tablet.

However, these public Wi-Fi connections are not at all secure. Here we explain why, and also how you should proceed to make everything more secure and not expose your device and your data to hackers.

Many coffee shops seem to have become the open offices of the 21st century. Even before the COVID-19 coronavirus crisis, it was easy to visit any Starbucks store and come across a sea of users with laptops or iPads.

Now, although many try to seek some privacy in the work they are carrying out, the truth is that the Wi-Fi connection in a public place like the one they are using is not secure and will be exposing them to other types of dangers.

Why is public Wi-Fi not secure?

The free Wi-Fi connection has a hidden cost and is called security. While we like the idea of being able to roam around a city by connecting to multiple Wi-Fi hotspots at no cost, this is certainly dangerous, as most of these networks are not encrypted.

In order to facilitate connections and avoid administration or supervision, these access points generally do not require a password to connect. When you connect, a web page appears asking you to enter an email address.

The problem with this is that the connection between your device and the access point is not encrypted. Therefore, some data will be sent in the form of plain text, which means that anyone could spy on your actions.

Worse still, they could set up their own access point and call it something like “Starbucks wifi.” Then people will connect to it without hesitation, giving the criminal easy access to all your unencrypted data or relevant information from you.

What are the dangers of using free wifi?

These fake networks look real and allow you to access the Internet as you normally would, but all they do is spy on you. Sooner or later, they will ask you to download something innocent looking that will contain malware to take over.

Another danger is that the Wi-Fi provider you connect to does not securely store the data that you used when registering. Sometimes these servers store the information on an Amazon server without a password, exposing everything to anyone.

Please note that when you log into any network, the device will store those details so that you can automatically connect again when you are within range of the network or come back another day.

For trusted networks like those in your home or office, this is fine. But when you do it from anywhere, this can turn against you. The fake network can impersonate another network to get the relevant information from your phone or device.

How can I make the public Wi-Fi connection secure?

The answer seems obvious: using a VPN connection.

A virtual private network (VPN) creates an encrypted connection between your device and a secure network server. If this sounds complicated, it really is not. Just install the VPN app and then enter your login details

Almost all VPN apps have a quick connect button that selects the closest or fastest server and it only takes a few seconds to connect.

The best apps have an option in the settings to automatically connect whenever your phone connects to public (unsecured) Wi-Fi, so you’re protected even if you forget to enable the VPN.

There are many providers and a wide variety of options, but you will find a comprehensive buying guide for this year’s best VPNs with our recommendations.

Two of the services are NordVPN and ExpressVPN.

Of course, the ideal solution would be for access point providers to enable encryption on your service, but this is not as simple as it sounds. As always, the biggest security threat lies in the need for convenience.

Most of these venues are informal spaces for customers, meaning they want to log in and log out quickly and seamlessly. Having to enter a password (or worse, a username and password) may not be that easy for some.

Although some hotels, restaurants, and other establishments already use encrypted Wi-Fi, in many cases the responsibility for protecting personal data rests firmly in your own hands.

One option is to simply avoid using any website or app where sensitive data is used while using the public Wi-Fi connection. But since this is inconvenient, the most feasible will be to use mobile data on your phone instead of Wi-Fi.

This is an encrypted connection, and you can generally set up a personal access point so that you can share that internet connection with a laptop, tablet, or any other worthwhile device.

Finally, it should be noted that some applications will use encryption even if the Wi-Fi connection is not encrypted. Banking apps are a good example, plus there are also messaging apps and email services that use their particular encryption.
