About WiFiWireless networks, often referred to as "WiFi", make it possible for computers and other communication devices to connect to each other using shortwave radio signals. A wireless network is open by nature. This means that anyone can simply tap into it and "listen" to the data being exchanged. Do you recall the story of the baby alarm that picked up the neighbours kids walkie-talkie, listening in on a wireless network is that easy. This is a heavenly situation for hackers the world over and can lead to some serious damage in terms of loss or personal information. In order to make your wireless network secure you will need to make some changes to how it works. First off you must know that the wireless signal can be picked up by any device equipped for reception at that frequency. This means the moment the network goes "up" all devices in the vicinity, which incidentally are always in stand-by mode waiting for the signal, will become part of the network. Here are some of the dangers that you face when using an insecure wireless network. BandwidthNearly all wireless networks have to share the bandwidth when connecting to the internet. A "freeloader" is someone who is an unwelcome part of the network that is using your connection to use the internet eating away into your bandwidth. This means that your internet connection will be working at a diminished capacity. If you find a sudden slow down in your internet speed then someone may be leeching off a healthy chunk of it for their own purposes. Several home based internet services put a limit to how much data you can download in a given month. In such a case you might end up paying a huge bill for things you have not done. The worst part about all this is that the "freeloader" could use your internet connection to do something illegal and that could come back to you. The authorities will trace back the internet signal to your computer and you will have to answer for whatever was done.EavesdroppingEavesdropping is when someone is doing nothing but listening to whatever you are doing. Listening here actually means monitoring your network activity. This means if you enter your banking account username and password over an unsecured network then someone can trap that information and then you are in trouble. Corporate information and personal information are both at risk when it is exchanged over an unsecured network.HackingHacking can happen even with a secure network when the hacker is determined to hack. However, unsecured networks are easy money for them and since most people are unaware of the dangers of wireless networks they make easy targets. This can be especially dangerous if you hook into a corporate network because then they can use your login credentials to access sensitive information. The danger becomes paramount because once a hacker enters the network he can then get access to administrator rights and can manipulate literally anything in the network. Standard precautions taken against hackers are useless in this case because the hacker has already bypassed all such security checkpoints. Wireless network equipment when used out of the box is especially vulnerable because no manufacturer enables the various safeguards that are a must to keep a network secure.
