What should we know about public Wi-Fi and its potential dangers

Why You Should Avoid Public Wi-Fi

While making the traveling to-do list, some people prefer to skip “Buy international travel SIM card” part, hoping for free public Wi-Fi connection in the destination country. Free Wi-Fi sounds great, but let us decide, is it really worth the hassle?
In the modern world, cybersecurity is a global challenge, it is not only an IT problem.

Using public Wi-Fi can seriously put your data at risk. The problem of public Wi-Fi is the open nature of the network, and connecting to public Wi-Fi can very often be incredibly dangerous for your shared information. Even the Wi-Fi in your favorite pub or coffee shop seldom uses strong encryption technology, as having a secure connection is rather expensive. So, anyone can see what you are up to over that particular network. They can monitor what sites you are visiting and even what you are typing into those websites. In case you are accessing encrypted websites, they know exactly which ones you are visiting, although if the site is secure, they can’t know what you are doing there.
