How to use public WiFi safely
WiFi is a service that appeals to anyone seeking internet access, whether with a laptop or a smartphone. Private WiFi networks require a password and are limited to users that the administrator allows to connect to the network.
On the other hand, public WiFi networks are open to everyone and can be used by anyone in the router’s coverage area. Although they are easy and free to use, public WiFi is not the safest place to connect to the Internet.
Tips for staying safe when using public WiFi
1. Verify the source
In public places such as hotels, cafes, schools, universities, etc., it is common to find public WiFi networks. At the same time, there are also people who create fake WiFi hotspots to steal your data. In a coffee shop or hotel, ask an employee about the available WiFi and its name before connecting.
2. Use a VPN
Using a VPN is a highly recommended solution and the best option when using a public WiFi network. Try one of the preferred VPN applications and activate it while using public WiFi. This helps keep your data encrypted and ensures that your browsing is private between you and the server.
3. HTTPS connection
If for some reason you can’t use VPN applications while on a public WiFi network, there is another way to stay secure. Use websites that have encryption so that your data doesn’t go anywhere except to the server. The HTTPS protocol tells you that the website is secure and that your data is kept between you and the server.
4. Activate your device’s firewall
Firewall protection is also an aspect you should rely on to keep you safe from potential attacks. Activate the firewall when connecting to a public WiFi network to protect your data and prevent unauthorized access.
5. Keep your system and security software up to date
It is essential to keep your operating system and security software, such as antivirus and firewall, up to date. Updates usually include security patches that protect your device from vulnerabilities and threats. By keeping everything up to date, you minimize the risk of falling victim to cyber-attacks while using public WiFi networks.
6. Avoid performing financial transactions or accessing sensitive sites.
When connecting to a public WiFi network, avoid activities that involve confidential information, such as banking transactions, online shopping or accessing sites with personal data. It is always better to perform these actions in private and secure networks, where the risk of exposure is lower.
7. Disable file sharing
Some devices have options to share files, printers and other resources on the network. Be sure to disable these options while on a public WiFi network to prevent other users from accessing your personal files or sensitive data.
8. Use trusted websites and applications
When surfing the Internet on a public WiFi network, it is important to use only trusted and verified websites and applications. This way, you reduce the risk of downloading malicious software or exposing your personal information to cybercriminals.
Using a public WiFi network can be convenient and useful in many situations, but it also involves certain security risks. By following these tips and taking extra precautions, you can enjoy the convenience of connecting to these networks without compromising your security and privacy.
