Principles to remember when using public Wi-Fi

In the digital age, public Wi-Fi appears everywhere: coffee shops, airports, hotels, shopping malls... Although convenient, this is also an environment with many potential security risks. To avoid becoming a victim of cyber attacks, you need to remember the following principles:

Do not access financial services or enter sensitive information

One of the most important rules when using public Wi-Fi is to avoid accessing financial services such as online banking, e-wallets or websites that require personal information such as credit card numbers, email passwords. Public networks are often not fully encrypted, making data vulnerable to hackers. If you must access, use a virtual private network (VPN) for added security.

Only connect to Wi-Fi networks with clear names and provided by reputable providers.

Not all free Wi-Fi networks are safe. You should prioritize connecting to networks with clear names, provided by reputable organizations such as hotels, airports, and large coffee shops. Stay away from networks with generic names such as “Free Wi-Fi” or “Public Wi-Fi” because these may be fake networks created by hackers to steal user data.

Turn off data sharing and Bluetooth features

Before connecting to public Wi-Fi, check and turn off data sharing features like “File Sharing,” “AirDrop,” or Bluetooth. These features can be used to gain unauthorized access to your device, especially when you are in crowded places like airports, shopping centers, or conferences.

Use a VPN to encrypt your connection

VPN is an effective security tool that encrypts all data transmitted between the device and the server. When using public Wi-Fi, VPN will create a layer of protection, preventing information from being tracked or stolen. Currently, there are many reputable VPN services such as NordVPN, ExpressVPN or ProtonVPN that you can easily install on your phone and laptop.

Always keep your software and operating system up to date

Devices with outdated software are vulnerable to security vulnerabilities. Make sure your phone, tablet, and laptop are always updated with the latest versions of their operating systems and web browsers. Also, install anti-virus software for added protection.

Forget network after use

After leaving the location, select “Forget this network” to avoid the device automatically reconnecting next time – an easily exploitable vulnerability.
