How easy a hacker can steal your profile, password and important data? With the advance of technology, there are now many simple software or even a browser plugin enable any person to do so. Even a teenager can read your profile and password with those programs when you are using Wi-Fi. For example, there is a famous Firefox browser plugin called “Firesheep Extention”. This is a very easy way to give you the ability to read other people’s profile and password when they are using Wi-Fi. In addition, there are also many other eavesdropping freeware for Wi-fi available which serve the same purpose.
Some experts say that around 95% of the Wi-Fi data traffic is unencrypted. Since it is very risk using public Wi-Fi, any solution available to overcome this?
Firstly, we should try to use https as long as that website support. Https connection is a secure connection which data was encrypted. Thus, even a hacker get the data, they will not know what that is about. For example, you can set Gmail to always connect that with https. Then it is safe even using public Wi-Fi. Yet it will only protect your Gmail profile and password. There are still many other web services you use may not support the https connection. Facebook, Twitter and many other web services does not support the https. In other words, we are still at risk
The most powerful method is using VPN. It is also known as Virtual private network. This would be the safest way you can connect to the net in public. The transfer of data will be encrypted with advanced method and it is like a private network for you. This will protect your profile, password and important data even you are using public Wi-Fi.
