Wireless Network Security

Nowadays possessing a computer has become a real necessity since most of the cultural activities are being carried out by means of computing.

Via Internet connection people gain information on different spheres(news, weather, sports, recipes, yellow pages and a million other things) thus emphasizing the existing of computer as not only a luxury but also a necessity.
The term Wireless network connection itself dictates that it is a type of computer network connected by no cables. Wireless telecommunications networks are generally applied and implemented using a transmission system called radio waves. Radio waves may occur naturally-as a result of lightning or by astronomical objects and artificially-generated radio waves which are applicable for mobile radio communication, broadcasting, navigation systems, computer networks and other applications at the physical layer of the network structure.
Wireless Personal Area Networks (WPANs) are implemented within a relatively small area, i.e. within a person’s reach and is called personal area network (PAN).
Personal area networks may be connected with USB and FireWire. By means of bluetooth data is exchanged over short distances by means of short wavelength radio transmissions from mobile devices.
The Bluetooth Core Specification provides the liason of two or more piconets to form a scatternet, in which certain devices serve as bridges, simultaneously playing the master role in one piconet as primary and in the other a secondary role.
Most WLAN hardware has got easy enough to set up that many users simply plug it in and start using the network without taking care of security. Nevertheless, taking several measures to configure the security features of your wireless router or access point is time well spent. Several measures should be taken in order to disable broadcasting;
1. Enable Encryption: encrypt your data so that only the intended recipient is supposed to be able to read it.
2. Unnecessary Traffic needs to be restricted allowing only incoming or outgoing traffic.
3. Change the Default Administrator Password. It is well known that if not changed the default passwords are easily obtained
Wireless network security is important in the home for the same reasons why it is important in corporations. If you have an unsecured wireless network in your home, anyone in close proximity can spy on your online activities. Depending on how your home network is configured, someone could even gain full access to your computer’s hard drive over an unsecured wireless network.
Wireless security can be broken into two parts: Authentication and encryption. Authentication mechanisms can be used to identify a wireless client to an access point and vice-versa, while encryption mechanisms ensure that it is not possible to decode data.
What You Need To Know is To Secure Your Wireless Network.

BlueAuditor enables the user to save the data of the detected mobile devices in an .xml file and supports the most Microsoft drivers available on the market. All the mentioned features are provided with a user friendly graphical interface.
The downside of a wireless network is that, unless you take certain measures, anyone with a wireless-ready computer can utilize your network. A hacker can apply an insecure wireless network to spy on you, or even to steal Internet .
In this article I have explained that unless you take some basic security precautions, your wireless network is very susceptible to intrusion. The Internet represents a new market, a new market of currency, and a new way for businesses to conduct operations electronically. While new technologies often increase opportunities, they also bring about controverse measures to undermine those opportunities. Let’s hope that in the aftermath all these efforts will not be in vain but only promising.
