The Dark Side of Free Wi-Fi: 8 Rules to Protect Yourself on Public Networks

Free Wi-Fi can be a real lifesaver when your mobile data runs low. Many users value it for convenience and the absence of any commitments. But what about the flip side? Those Wi-Fis pose many security risks. Want to keep using them? Learn and adopt these eight techniques for unparalleled safety.

8 Rules to Help You Stay Safe on Public Networks

1. Use a Proxy

A proxy server takes the role of a middleman between your device and the internet. It can effectively mask your IP address and so make your connection more anonymous. While it does not encrypt data like a VPN, it helps hide your location and identity from attackers.

But beware — not all proxies are created equal. Use sites similar to proxybros.com to find the best options on the market. Similarly, don’t get overexcited about free proxy services — their speed and quality are usually much lower.

2. Disable Automatic Wi-Fi Connections

Many devices automatically connect to saved networks. Hackers exploit this by setting up fake networks with familiar names. Although the function is quite handy when dealing with familiar networks, it can cause much trouble when in new places. 

The solution? 

• First, read the network’s name carefully.
• Second, better turn off the auto-connect feature.
• Third, check the box “forget network” after you use a public Wi-Fi (we’ll discuss this one a bit later in more detail).

3. Avoid Logging into Sensitive Accounts

Public Wi-Fi is not the place to check your bank account or enter passwords. If an attacker is monitoring the network, they can steal your credentials. Thus, if you have to deal with sensitive details, switch to your mobile data. It’s an extra step, which, however, will guarantee your security.

4. Turn Off File Sharing and Bluetooth

Leaving file sharing or Bluetooth active makes your device vulnerable. AirDrop is just one popular example of a feature you’d like to turn off. Here’s how you can do this, depending on your operating system.

For PC

• Open Network and Sharing Center.
• Click Change advanced sharing settings.
• Disable File and printer sharing.

For Mac

• Open System Preferences.
• Select Sharing.
• Uncheck all options.
• In Finder, go to AirDrop and set Allow me to be discovered by: No One.

For iOS

• Open Control Center.
• Locate AirDrop and switch it off.

5. Stick to HTTPS Websites

Sites using HTTPS encrypt your connection, adding extra protection. HTTP sites do not, making it easy for hackers to intercept and manipulate data. Thus, they are more likely to serve malevolent purposes.

It’s good practice to always check the website’s connection — the information appearing before “www” in your browser. Although HTTPS connections won’t wholly guarantee your security while on a free network, they still serve as a good sign of trustworthiness.

6. Use Two-Factor Authentication (2FA)

Even if a hacker steals your password, 2FA blocks access. It requires a second verification step, like a one-time code sent to your phone. Without this code, an attacker cannot log in.

Enabling 2FA may require some time; however, the step is worth it. Complete it for all important accounts — email, banking, and social media. For extra security, it’s advisable to use an authenticator app instead of SMS.

7. Forget Networks After Use

Your device saves Wi-Fi details to reconnect faster. This convenience can be risky if someone spoofs a saved network name. Here’s how you can forget the public network, depending on your device.

On iPhone

• Open Settings and go to Wi-Fi.
• Find the network you want to forget on the list.
• Tap the “i” icon next to it.
• Select Forget This Network and confirm.

On Android

• Open Settings and go to Network & Internet.
• Tap Internet, then find the Wi-Fi network.
• Select the Cog icon next to the network.
• Choose Forget to remove it.

On Windows 10

• Open Settings and navigate to Network & Internet.
• Click Wi-Fi, then select Manage known networks.
• Find the network, click on it, and select Forget.

On Mac

• Click the Apple menu and open System Preferences.
• Go to Network Preferences and select Wi-Fi.
• Click Advanced, then navigate to Manage known networks.
• Select the network and click the Minus (-) icon to forget it.

8. Install a Strong Antivirus

A good antivirus can detect and block malicious software distributed by hackers before it can cause damage. Once you download and install a reputable antivirus system, you add an extra shield of protection.

But remember to keep your antivirus program updated for the best protection. Additionally, launch automatic security scanning to detect and address any suspicious issues promptly.

Conclusion

As you can see, free networks can harm your devices and data. So, whenever you use them, be sure to employ these eight tips for better security. Remember that your online safety starts with your actions.
