Attention: How to protect your data from WiFi dangers while on vacation!
Public Wi-Fi networks are particularly tempting when on vacation, as they offer a convenient way to go online. However, Tino Melzer, the Thuringian State Commissioner for Data Protection and Freedom of Information, warns of the security risks associated with the use of these hotspots. Whether in hotels, holiday apartments or cafés, connecting to unsecured networks can have serious consequences. Eisenach Online reports that great caution is required not only on vacation, but also in everyday life.
“These WLAN networks offer convenience, but pose security risks,” explains Melzer. The dangers posed by unencrypted and password-free networks are diverse. It is often unclear whether the WLAN actually belongs to the operator or whether it is a “WLAN phishing”. In addition, hackers can easily gain access to such networks and spy on sensitive data.
Take security measures
Melzer recommends deactivating automatic WiFi connection on devices. This prevents unwanted connections to unsecure networks. When consciously using public Wi-Fi, you should also make sure to select the network directly and surf carefully. Downloading unknown links or documents should be avoided.
Recommended security measures also include using VPN connections to encrypt data and mask location. How PC world As explained, many VPN services are chargeable, but there are also free options, for example in the Microsoft Edge or Opera browser.
PC-Welt also advises making various settings before connecting to public WLANs. This includes enabling a changing MAC address, which makes it difficult to identify the device. Changing the profile to “Public Network” also deactivates file and printer sharing.
Technical tips for Windows users
There are specific recommendations for Windows 11 users to increase security when using public Wi-Fi:
- Wechselnde MAC-Adresse aktivieren: Dies kann in den „Einstellungen –› Netzwerk und Internet –› WLAN –› Eigenschaften von [WLAN-Name]“ eingerichtet werden.
- Profil umstellen: Auf „Öffentliches Netzwerk“ wechseln, um die Datei- und Druckerfreigabe zu deaktivieren.
- Anpassung des DNS-Servers: Um Manipulationen zu verhindern, wird empfohlen, bevorzugte DNS-Server wie Quad9 (9.9.9.9) zu nutzen.
The availability of free WiFi networks is constantly growing, especially in cities, train stations and cafés. But the security of these networks should always be a priority. With the right precautions, surfing the Internet can be made safer, even while on vacation.
