It is very common to browse the internet through mobile devices nowadays. In fact, they have even replaced computers in many cases, as we can browse, use social networks, make purchases, or use various applications just as we would on a PC. However, this convenience also comes with risks. One of them is that we may connect from insecure Wi-Fi networks when we are on the go. Is there anything we can keep in mind to determine whether these networks are trustworthy?
What to do to see if a Wi-Fi is safe on the mobile
It is important to be aware of certain factors when connecting to a Wi-Fi network using a mobile device. The presence of a password and the type of encryption used are crucial to determining the network’s reliability. While the type of encryption used does not guarantee complete security, it provides a good indication of the network’s level of protection.
It is advisable to avoid connecting to open networks, as anyone can access them and they may be set up as traps to steal data. For instance, networks labeled “Free WiFi” at airports could be fraudulent.
To determine if a Wi-Fi network is secure on an Android phone, go to Settings, then Connections, and click on Wi-Fi. From there, click on Settings to view important information, including the network’s security details.
The image above shows that the mobile device is connected to a Wi-Fi network that uses WPA/WPA-2 Personal encryption. Although WPA-3 would be the most secure encryption, WPA/WPA-2 is still considered strong and makes it difficult for an attacker to crack the password and gain unauthorized access to the wireless network.
However, if the encryption used is outdated, such as WEP, the security of the network can be compromised. In such cases, an attacker can launch an attack to break the password and gain malicious control over the network.
Use VPN, best for public networks
To ensure complete security while browsing through public Wi-Fi networks, it is best to use a VPN. This software encrypts your connection, creating a secure tunnel through which your data is transmitted. Even if there are intruders on the network, they won’t be able to see your data.
However, it’s important to be careful with VPNs and avoid using free ones that can compromise your privacy. Make sure you choose a reliable and trustworthy VPN by doing some research on the internet.
When using public Wi-Fi networks, such as those found in airports, malls, and libraries, it’s best to avoid sending sensitive information, making payments or purchases. But if you need to do so, using a VPN can provide an extra layer of security.
