Weaknesses / Threats Network Wifi (Wireless Fidelity)

Security issues is very important in computer networks, especially in wireless networks. The presence of many vendors of wireless products serving a variety of products at prices affordable to drivers of contributing to widespread use of wireless technology. This wireless technology is not only suitable for use in office or business users. Home users can also use this technology for easy connectivity. This paper is directed to provide information on threats as well as quick and easy way to secure wireless network. As already discussed in the beginning, the wireless technology is relatively more vulnerable to security problems. As the name implies, wireless technology uses radio waves as a means of data transmission. Security processes will become more difficult because you can not see radio waves used for data transmission. Read the rest of this entry »

Flexibility and convenience are the connection of the most positive impact we feel when using Wi-Fi networks. However, Wi-Fi connection also keeps its own security risks. The nature of the wireless indirectly crack your PC open to anyone who participated and if necessary tap data traffic is transmitted in Wi-Fi networks.
Until now, two security standards in Wi-Fi networks are presented. Adalam first standard WEP (Wired Equivalent Protocol), followed by the WPA standard (Wi-Fi Protected Access).

Because the radio waves emanating kesegala hotspot direction, anyone around the hotspot will catch this wave and try the ? meliha t contains. Anyone can freely elihat ? ersliweran ? data on the network. This condition is similar to LAN switches sebuat lay public place, such as the corner restaurant or cafe. Whoever restaurant or cafe will be able to plug the network cable to him. If you have connected to the switch, the The access will be able to do a light into the local computer where the switch is connected. He can do lalau ? encurian activity data from the computer network. Such was the wireless network. Anyone can easily join, access, and even steal data available on these wireless networks. Wireless network model If so, what will be forbidden to interfere with the attacker do a wireless connection user, this depends on the model of wireless networks used by a hotspot, and security validation method used and the internal configuration access point. So far there are several models of wireless networks used in a hotspot, particularly in hotspot areas are common, such as malls, exhibitions, or other public places.
