There is no doubt that wireless internet has increased productivity and improved communications. Users can join wireless networks at school, in airports and hotels, and even restaurants. However wireless connections may not always be safe. Many public Wi-Fi spots are not secured and users are at risk of exposing sensitive information and data.
The information you send over an unsecured Wi-Fi network is not encrypted. Always keep that in mind when decided what information you are sending. A user should always know what network you are joining. In an Evil Twin attack, a user is tricked into joining an imposter network that mimics the authentic public access network. Once the user joins, the attacker can easily intercept sensitive information.
