Security of WiFi networks continues to be an issue. With an unsecured network, outside users may access signals without any authorization. This allows unwanted users to use WiFi. With a secured network, unwanted users from the outside cannot gain access without knowing a specified network key and password. This also prevents people from using another person's WiFi connection for free. Most business networks attempt to prevent outside access to their networks in order to protect sensitive and important information. This makes networks a target for "hackers" who aim to access important information for their own unauthorized uses.
