Wireless Network
The increased demand for wireless networks in the recent period, but we can say we are in transition from traditional to Web radio network, and because they provided such networks easier and freedom of movement inside the building one without affecting the operation of the fully mobile phone network, which You can campaign wherever they want. The low prices have also contributed to the proliferation of these technical terms are no longer the costs of building a network of wireless expensive as in the past, competition between companies contributed to the acts cost to less than half, and you can now build wireless network in your house an internal 50 riyals only.
Wireless networks are an excellent choice for places that are difficult delivery closed wires, or might not wish to deliver wire from the base to maintain the general appearance, or those where a lot of architectural changes. We note the proliferation of wireless network in many cafes and shopping centers in the Sultanate.
Factors that must be considered during the construction of the wireless network is to know the relevant criterion to be used in the network, and there are a lot of criteria established by the Institute of Institute of Electrical and Electronics Engineers (IEEE), including : 1-standard 802.11b, which provides the data transfer speed up 11 megabytes / second. 2-standard 802.11g, which offers the highest speed I hit 54 megabytes. A choice of the appropriate standard for wireless network, which intends to build is very important, and in all cases, I advise the second criterion is if there is financial possibilities.
When it starts to talk about the security aspect of computer networks We are adjusting our meeting and take a deep breath and begin to focus more of this side of importance, and I think that the situation would be even worse if all the talk about wireless networks, and the reason for that is that the feeling that our information and our Stsubh in the sky will fall like rain and possibly in the hands of those do not want them, which is a violation of our own, it is not so bad, wireless networks with standards of protection to help them gain the confidence of its clientele, a criterion X802.1 responsible for the protection of the network for adoption the principle of control users entering the network and ascertain their suitability in the access to available data it. To add further protection to the wireless network protocol has been adopted encryption called Wired Equinalent Privacy and abbreviated (WEP). Here identify the necessary steps to protect the wireless network :
1-determining the appropriate place for access points : the radio frequencies easy access from the walls, so that the thick, to reach a point near one of the walls of the building could easily spread to the vibration abroad, which helps others to pick up. Try to choose a proper place in the middle of the building.
2-activate encryption protocol for wireless networks (WEP) : This technical provide 40 bit and 128-bit encryption levels, helps you to prevent infiltrators from entering the network, and recommend more protection through the promotion to (WPA), which refers to access protected the Wi-Fi network, which is the new generation of protection.
3-change service ID (SSID) : As is known, the access point labeled own is usually determined by the manufacturer, we recommend changing the name to any particular name immediately after operation of the network.
4-Disable DHCP : is equipped with a DHCP IP tariff figures regardless of all devices that relate to the network to be able to identify each other, and in spite of the many privileges afforded equipped with a DHCP but it is not recommended in high levels of information security protection, so orientation the exchange identification numbers manually.
But if you are looking for higher levels of safety Vansahk threw this article aside, I am not obliged to focus again, because I am not personal beliefs in every swim in the broad space for fear that captured the criminal hands, so that the Governments of the countries of the world to prevent the exchange of information on wireless networks .
