Pay attention with free Wi-Fi access
- +Free Wi-Fi, why??
- Many organizations today give free Wi-Fi while you visit. This is of course to attract customers. It’s easier to go to a restaurant where you can find wi-fi to stay connected than to a restaurant that doesn’t. This case is not a specialist in Wi-Fi, but does this to make sure you get to them.
- +What can happen with the free Wi-Fi?
- It’s usually not the owner who has bad intentions. No, he just installed this Wi-Fi to keep you in his business. But you don’t know who else is in this restaurant, or who’s around the corner. Because the Wi-Fi doesn’t stop at the doors of the restaurant. And that’s where the danger is. It’s easy to intercept what you’re doing on the network, so just imagine that you’d like to use your smartphone to pay the restaurant’s bill via Wi-Fi. There’s a good chance that your data will be misused.
- +Are there alternatives?
- Yes, our phone data subscriptions are no longer that expensive and our data connections are quite large. So switching to 3G or 4G connection of your phone makes everything a lot more difficult to intercept.
If it doesn’t work out just like that, you can also use the hotspots that are often made available by your provider. These settings come directly from them and do comply with the necessary security levels. On these, someone with bad intentions can’t just watch what others are doing. And if so, you can quickly find out who did all this.
- +Tips from PaSMaN?
There is no such thing as free, and if it is free anyway, it means that they try to make their money in other ways. And this is also true here. If you get free Wi-Fi in a hotel, cafe or other place, then this is very sympathetic from the owners. But these owners are good at keeping a hotel or cafe open, and not necessarily IT specialists, so there is a real chance that their Wi-Fi network is not optimally protected. And if you get easy access, so do others. And you never know whether they have good or bad intentions.
Pay attention to free Wi-Fi access
Today, we can go anywhere online via a Wi-Fi connection. Just at home, at the cafe on the corner, the sandwich shop, shops and airports, in some cities you can even connect to the city’s network. However, there are a few points to keep in mind.
Surfing on a Wi-Fi network is not necessarily safe, if your wireless connection at home is properly secured with a strong password it is relatively safe because only you and a limited group of friends and family that you trust use it.
The free Wi-Fi connection of the corner café is often not secure, even if it is password protected. Anyone who comes can use it, so you don’t know who else is connected to that network. The password has probably not changed in the last year, is known by many people and so there is a good chance that there is someone among them who don’t always have a good time with someone else. On a network, it is possible to receive and read all communication, which means that every website you request, every photo you look at, every mail you send or questionnaire you fill in can be read along with it. The only way to safely use such networks is by using an encrypted connection (SSL or VPN) or by switching to the 3G/4G data connection of your mobile phone subscription. A data connection of your GSM subscription is always personally linked to you and makes a direct connection between your phone (or other devices) and the provider. This is not just shared in a public space and will, therefore, be much more difficult for people with bad intentions to access.
