Growth of Wifi networks is still on going world wide this huge growth raises security issues. Wifi is the most widely used network world wide and many organizations transfer their sensitive data using Wireless networks. Increased use of Wireless network increases potentially risks of the security of the users or organization. Wireless network carries data of every type, that can be normal data in bits of information or it can encrypted or even highly sensitive. Wifi security mechanism insures the certain level of data integrity and confidentiality just as wired network provides. However if proper security measures are not adopted properly intruders can attack the network and can cause major damage to not only network but privacy of users also.
There was a time when cables were used to network many computers together. Hardware like routers, hubs, switches etc were required for communication between computers, but Wifi brought high tech change in communication of computers by providing wireless connectivity features. It just keeps things very simple without much hassle and networks can be made far more easily. No wires are required. Wireless network keeps environment very neat and clean. There are many other features of Wireless LANs for example high speed connectivity. Wifi provides high speed connectivity and faster communication where cables are not feasible to install for example in remote areas. The list of the Wifi features is long some other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, End user mobility and easy access through Hotspots.
Wifi supports two different types of modes; they are known to be infrastructure and the other one is ad hoc. In Ad hoc Wireless connections can be made without central device called router or access point. Most network administrators prefer ad hoc over infrastructure mode. Ad hoc how ever have issues also. Wifi devices connected using Ad hoc mode offers less security against unauthorized users. Ad hoc mode configured devices cannot disable SSID broadcast in contrast to infrastructure mode, this brings hackers into play, and using ad hoc mode it is not very difficult to prevail into the wireless network. There are two major differences between these two modes that is the rate at which they transfer data. Wife network standard 802. 11g requires Ad hoc mode of communication to support 11Mbps bandwidth in contrast to it 54Mbps data transfer is supported using infrastructure mode. Hence Ad hoc mode is considered much slower than Infrastructure mode.
