Free public WiFi is available almost everywhere these days, whether in coffee shops, hotels, airports, restaurants, libraries or other public places. When you are out accessing the internet, free time is very convenient. It enables you to work, communicate or use the internet without any interruption wherever you are.

But there are also public wifi security risks. When you are connected to a public network, you are leaving yourself open to hackers, snoops and cyber criminals who may also be connected to the same hotspot. With the right tools, your online activity could be snooped by a dangerous actor on the same network that could steal your personal information and login credentials, infect your device with malware, and more.

This does not mean to avoid public WiFi networks completely; they are too useful to avoid completely. But you have to be aware of the public wifi security dangers and take precautions for public WiFi security. This all-inclusive guide is related to public WiFi security and how to be safe while using public Wifi.

What is Public WiFi?

Public WiFi is something that most people have been using without even thinking about it in their everyday lives. It’s fast, free, and easy to obtain, but it will help you to use it more safely when you know what it actually is.

Public WiFi Explained in Plain Language

Public WiFi is any network that is public, or that many people can access simultaneously. You’ll commonly find it in places such as cafes, hotels, airports, libraries, malls, schools and restaurants, where anyone may connect with the help of a password or, in some cases, even without passwords.

Why Do People Rely on Public WiFi so Often?

In terms of why people choose to use public WiFi, people use it because it saves mobile data and also makes it easy to get online without additional cost. It’s especially useful when traveling, and it’s helpful for remote workers and students who are away from home. In some cases, it just becomes more convenient than creating a personal hotspot.

Public WiFi is Easy to Use, But not Always Easy to Trust

While public WiFi is fast and convenient, there are certain risks associated with using it that most users don’t think about and that’s why understanding how safe these types of networks really are is important to know before relying on them.

Understanding the risks is the first step; protecting yourself is the next. NordVPN encrypts your public WiFi connection and keeps your data safe wherever you connect.

The Public WiFi Security Risks

Before getting into the specific safety tips for public wifi security, it’s important to understand exactly why public wifi poses security and privacy risks, so you understand why you need to be careful.

Unencrypted Connections

The greatest problem is that public WiFi connections are not always safe. This means that anyone else on the network can view the information that you are sending and receiving. They have access to easy-spy tools to pry into what you’re doing on the Internet.

Man-in-the-Middle Attacks

Hackers are able to do a “man-in-the-middle” attack. This is when they secretly get in between you and the websites that you visit. They are able to see things such as your passwords or read your emails. They can even change the content of the site before it reaches you.

Rogue WiFi Networks

Sometimes, hackers will establish fake WiFi networks. They make them look like real ones and trick you into connecting. As you make a connection, they can steal your information or install malicious software into your device (called malware).

Malware Distribution

If the security of your device is not up to date, hackers can use public WiFi to put viruses on it with security. This poor software can then steal your data, spy on your activities or even lock your files, demanding you hand over money.

Snooping and Sniffing

With readily available tools, hackers can spy on what other devices on the WiFi are doing. They can see what you browse, files you send, and even access folders on your device. If you have to share, they can see everything.

How To Stay Safe Using Public WiFi?

While these threats may be alarming, there are various steps you can take to be safe when using public Wifi hotspots.

Use a Virtual Private Network

One of the best public WiFi security methods is to use a virtual private network (VPN). A VPN establishes a path between your device and a remote server for a secure, encrypted connection and all your traffic is routed through that path, so hackers cannot read/intercept your data.

It conceals your IP address, masks your location, and encrypts and secures your activity by using an encrypted tunnel that becomes much more difficult for people on the same network to spy on your activities.

Verify Public WiFi Networks

When you join a public Wi-Fi, you must ensure that you are connecting to the actual network and not a fake network created by hackers. These fake networks often closely resemble similar names to deceive their users, enabling these users to view everything you do online.

Always make sure you are connecting to the correct network by looking at official signs or asking staff to help you. Never connect to open networks if they are available and double-check when connecting to avoid walking into a trap.

Turn Off Sharing

When using public WiFi, it is crucial to turn off your file and folder sharing because other users on the same network may be able to access your information if file and folder sharing is turned on. Disable file sharing and printer sharing as well as network discovery on your device to avoid unauthorized access.

This is used to help keep your files hidden, as well as your device hidden from others on the network.

Enable Your Firewall

A firewall provides an additional layer of protection by monitoring and filtering the incoming and outgoing traffic investments, according to security rules. It serves as a barrier between your device and the potential threats that are on public WiFi and thus makes it more difficult for hackers to obtain access to your device.

While not entirely a solution, it does help you strengthen your overall security when your firewall is enabled.

Use HTTPS and SSL Whenever Possible

Always try to visit websites that use HTTPS, as it enables the encryption of the connection between your browser and the website, making it difficult for hackers to intercept your data. Look for “https://” and an icon of a lock in the address bar and don’t go to sites with plain old Google.

There are additional features that you can also use to make secure connections, such as DNS over HTTPS, or you can use browser extensions to enforce secure connections.

Be Careful Of Public Charging Stations

Public USB charging stations can be dangerous because of “juice jacking,” where hackers can use the public USB charging stations to steal your data or install malware on your device. Since USB ports can be used for data transfer as well as power, it is best not to use public chargers if you can avoid it. Instead, use your own adapter, power bank or USB data blocker in order to stay safe.

Disable Auto-Connect

Auto-connect function: Auto-connect can be used for your device to join networks that you are not aware of or that are insecure. Turn off this setting and manually select to which networks one connects. Also, forget about public networks to avoid the possibility of your device connecting automatically upon use in the future.

Keep Your Device Updated

Keeping up with updates of your device, apps, and browsers is very important for security purposes because updates will patch up vulnerabilities that hackers may attack. Make automatic updates so that you always have the most up-to-date protections. Updated antivirus and security tools are also helpful in the process of identifying and preventing new threats effectively.

Use Two-Factor Authentication

Two-factor authentication (2FA) is an additional level of security that requires you to go through a second system of authentication in addition to your password. Even if someone gives your password, on the public wifi, they won’t be able to get into your accounts without the 2nd factor. Enable 2FA on important accounts for improved security.

Log Out and Clear Browsing History

After using the public wifi, always remember to log out of your accounts and clear your browsing history, cache and cookies. This ensures that other people cannot access your data if they get access to the network. Closing all browser tabs/sessions to be sure that no sensitive information is left behind.
