How to use a VPN for online privacy and data encryption
VPNs & Public Wi-Fi Security
VPNs are valued for online privacy, but you can also use them to provide security for your online activity while using public Wi-Fi hotspots. Threats in this area include different types of man-in-the-middle attacks.
In Man-in-the-Middle or MITM attacks, cybercriminals get in the middle of the computer or mobile device and the website you’re trying to access, and intercept your connection to eavesdrop or even tamper with it. Examples of MITM attacks include:
snooping and sniffing
The hacking software on other users on the same public Wi-Fi is easily available on the internet. With this software, other users can see the online activity of anyone else on that network.
“Evil twin” Wi-Fi hotspots
Cybercriminals can set up malicious Wi-Fi hotspots to trick people into connecting to the wrong network. These hotspots are often called “evil twin” networks, because they are often set up to look like the real thing, such as “Wi-Fi in a coffee shop” vs. “Wi-Fi at a shop WiFi” or “LA airport Wi-Fi” vs. LAX” Wi-Fi at the airport. “
In these types of hacks and attacks, cybercriminals can gain access to your online activity and valuable information that you may enter, such as your login credentials or credit card numbers.
This is why using a VPN is important when using public Wi-Fi networks.
A VPN protects your Wi-Fi activity, to help protect against snooping and cybercriminals from accessing your information. So even in an unsecured network, you can help keep your information safe with a VPN.
