Wireless security is all about keeping your information safe and secure while you use a wireless internet connection. Think of it like a door that you put up around your house that only lets people in if they have a special key. Wireless security works in much the same way - only those with the right key can access your information. Wireless security can be done with passwords, encryption and other security techniques. All of these techniques help to make sure that your information is safe and secure while you are using a wireless connection.
