Wi-Fi allows users to connect to the internet or a network without a wired connection. A computer with a Wi-Fi card can connect to the internet with a router, which is an access point. A router connects directly to the internet or to a network with the help of a broadband or DSL, which is in-built. There are 2 types of network and these are open and closed Wi-Fi networks. With a closed network you need to fill in a password before you access, but open networks can be accessed by everybody. A wireless hotspot is an area that has an open Wi-Fi network. These hotspots can be found in a lot of restaurants and libraries. So, now the question comes “Is Wi-Fi Secure? or Not?”. Let us discuss and find out some specific points about this topic below.
Problems with Wi-Fi :
When you log onto a Wi-Fi network at the office or at home it is not the same as logging on at a public area. You cannot trust that your data will stay confidential when you log in at a public place and these places do not take responsibility for their users personal data. Therefore, users need to make sure that they protect their data when accessing the internet in a public area. A good way to keep data safe is by using a personal VPN.
Personal VPN’s :
A VPN makes sure you can access the internet securely, as all the data you move between the network and the computer is encrypted. A VPN prevents communication over a public network being viewed, intercepted or stolen by other users. Also possible incidents of hacking are prevented when you use a VPN.
You can see a VPN as a tunnel through which data moves. Because the data is encrypted and nobody but you can intercept this. When data does get intercepted, it looks like codes that nobody understands. Only when you use a decryption key will you be able to understand it.
Nowadays, many firms give their employees a personal VPN and this enables them to browse the internet a lot safer.
