Free or Public Wi-Fi’s are a convenient way to stay connected to the web when you are on the go or not at home. But these types of connections are open and can pose risks to your device’s security. Here are some tips to keep safe when connecting to these types of Wi-Fi.

Verify the Network

When you are staying at a library or café the easiest way to stay safe when connecting to their Wi-Fi is to ask the staff for the name or SSID of the network you would connect to.

Customize your network settings

Another way to keep safe when connecting to public Wi-Fi’s is to turn off your file sharing and mark the Wi-Fi network as public. For Windows Users you can find these settings in the Control Panel > Network and Sharing Center > Change Advanced Sharing Settings.

For Mac users, open up your System Preferences and look for the Sharing icon then uncheck File Sharing. Additionally, you should also disable your guest account and remove unneeded share points to prevent others from accessing your Mac device. For disabling guest accounts and removing unneeded share points follow the steps below.

Disabling Guest Account — Go to Apple Menu > System Preferences. Click on Users & Groups. Click on the lock on the bottom left corner of the screen and enter your password to unlock. Click on the Guest User Account to select it. Uncheck Allow Guests to Log into the Computer. Click on the lock to re-lock the preference.
Removing Unneeded Share Points — go to the Sharing system preferences and select the File Sharing section. Here you will see the Public folders for each account. To remove these folders simply select them and click on the minus button.

Use a VPN

VPNs (Virtual Private Networks), aside from faking which country you’re in, provide additional security and privacy to your connection by encrypting and tunneling the data you send and receive and by replacing your IP address. VPNs can be used by PCs and Mobiles alike. Be wary though and only use trusted VPN providers as this could backfire and instead of protecting your device you might endanger it.

Stay on Secure Websites

Always check which websites you are visiting. Certain browsers, like Google Chrome, would send out warnings whenever you are entering a site with an unsecured connection or unreliable security certification. This would most probably be denoted by a red crossed out padlock on the address bar while secured websites would be denoted by a green padlock.

Enable any Extra Security Measures

If your device or app has extra security features like two-factor authentication or secondary pins then it would be wise for you to use them. In an event that you would be compromised due to connecting to a public Wi-Fi then at least you have another layer of security.

Forget Networks

Once you disconnect from any Public or Free Wi-Fi’s it is advised that you forget it, this would prevent your devices from auto connecting to these networks and any similarly named ones in the future. Below are the steps on how to forget a network connection.

• For Windows users – uncheck the “Connect automatically” box on the network’s name before connecting to it. Alternatively, you could go through the Control Panel > Network and Sharing Center click on the networks name then on “Wireless Properties” then uncheck the “Connect automatically when this network is in range.” Box.
• For Mac Users – Head to System Preferences look for Network then under the Wi-Fi section click on Advanced. Under the advanced section uncheck “Remember networks this computer has joined.” You can also remove any other registered networks by selecting them and pressing the minus button.
• For Mobile Users – Long press on the network’s name and select “Forget Network”

Being aware and cautious of these potential pitfalls can save you a lot of headaches. Just do the routine checks on a regular basis and just be mindful every time you ask for the WiFi password.
