Dr. Yasser Elmalik Ahmed Seleman Abstract-Network is a technology used to connect computers and devices together. They allow people the ability to move easily and stay in touch while roaming the Internet in the coverage area. This increases efficiency by allowing data entry and access to the site. Comparing wireless networks wired networks in terms of cost, we find that wired networks are more expensive due to the cost of the network connections of electricity and running and add computers and change their positions to suit the network supply.\par
As a result, the use of widespread wireless networks. But there are security gaps in these networks may cause problems for users Security holes intended problem or weakness in the wireless network system may make it easier for hackers to penetrate and steal sensitive data and causing material losses to individuals and companies.\par
Knowing security holes and contributes significantly to the wireless network is immune from attempts to infiltrate and penetration design.\par

\section[{WIRELESS NETWORKING PROBLEMS}]{WIRELESS NETWORKING PROBLEMS}\par
Piracy operations on wireless networks in the recent period have become very many and varied the discovery of serious piracy operations targeting wireless routers (routers) to conduct malicious those changes, as the number of devices that have been controlled so far to 300 thousand sets of various types, including D-Link, Micro net, Tend, TP-Link, and other network routers. Hackers have resorted to the use of a variety of techniques that helped them access to these devices and make changes on the DNS system which is used to translate domain addresses and routed to the IP device user address of the computer to determine the device-specific Web servers, according to the published report pointed out last Monday by researchers at security firm Team Cymru.\par
This allows the penetration process to hackers planted a blank password in the wireless routers for users of type TP-Link words, in addition to the other way allows them to control the passwords for wireless network WPA / WPA2 remotely, So far, these attacks, involving more than 300 thousand sets in a wide range of countries, include India, Italy, Thailand, Colombia, and Vietnam. The ultimate goal of this process is to redirect end users to malicious sites trying to steal your bank accounts passwords.\par

Volume XVI Issue II Version I professional breaking this protocol over a short period, and are advised to use protocol (WEP) with key length of 128 bits, because it provides protection better than the shorter 64-bit key, and the key is created in the access point can then be copied to any device that is connected to the wireless network, and called this kind of common key encryption key (PSK).\par
Second Protocol (WPA) is the best protocol of the previous protocol, which provides the strongest encryption level, and often access and calling cards in the devices available in the market points of support over the past three years of this Protocol, and the availability of new operating systems support for the use (WPA), and can be used with an encryption key is shared (PSK) and with the encryption algorithm (TKIP), in Windows XP called Protocol (WPA -PSK), where should the user to copy the encryption key for the device to be connected to the wireless network, and can be used on a larger scale in institutions using Documentation / EAP 802.1 and in which the use of electronic certification mechanism.\par
Third Protocol (WPA2) which is an enhanced protocol (WPA) features that uses AES algorithm for encryption, it is also used in the bilateral networks, adhoc, and is available in a way (PSK) or using documentation / EAP 802.1 mechanism during which he can use the electronic certificates. necessary to fill these gaps exposed millions of users at risk. 
\section[{III. PROTECTION FOR WIRELESS NETWORK}]{III. PROTECTION FOR WIRELESS NETWORK}\par
Researcher explains a number of actions that should be applied to protect wireless networks are summarized below: 1. must be protected access as a user point and password are brought in whenever the user wants to change the settings of the access point, it should be noted that the new access points (or which has been to restore the default by the settings) be password-protected recognizable by the manufacturer, so be on the initiative to change the user password in order to avoid hackers to enter a network and controlled by changing the settings of the access point, and in general should the user choose the appropriate password consists of at least seven boxes to be a mixture of letters and numbers. 2. The most important protection methods are concentrated in the wireless network is encrypted, and there is more than one system (or so-called encryption protocol), a different protection force. 3. must wireless network ID change (SSID) so that does not imply access point type or her whereabouts, the default in new access points indicating the access and manufacturer her point type, allowing hackers an opportunity to attack the access and control points, taking advantage of the special gaps, You should also disable the announcement of the access point identifier option (Broadcasting SSID). 
\section[{Researcher also adds steps to protect your wireless network 1. Encrypt wireless network}]{Researcher also adds steps to protect your wireless network 1. Encrypt wireless network}\par
This step is the most important action taken to protect the wireless network. Used encryption means today is (WPA2) and (WPA-PSK) and (WEP). Without that go deeper in the encryption techniques (WPA2) is the latest in the world of encryption cry very favourite to buy Router supports this technique. By this encryption can be used for complex password consisting of 64 box (large and small letters, numbers, signs) and recommend everyone to exploit all available fields at secret word set. But how you will remember the pin number composed of 64 boxes? There is no need to write a PIN every time you want to enter the wireless network because it will remain preserved in the network settings, but preferred to write a PIN number on file Txt and keep it on an external USB memory card. Older routers used type of encryption technology (WPA) Note that the previous encryption (WPA2) better than him. For encryption (WEP) never think about using it because it is considered a weak encryption and can penetrate the network within 4 hours (maybe a few minutes) using special software. 
\section[{Use the MAC Filtering}]{Use the MAC Filtering}\par
On each network card there is a special code called Pal Mac Address distinguishes it from other network card. I picked up a picture of your network card so you can see the Mac Address. In the router settings you can adjust most settings, so that this does not fall on the wireless network, but according to a specific list of Mac Address. Year 2016 ( ) E Fig.  {\ref 2} : Piracy aimed at wireless routers (routers) 1. Use a firewall Firewall software on your mobile device. 2. Free hot contact points are often less secured than that paid. Points are paid to follow-up and protection of process and change all safety requirements have with encryption. 3. Turn off file sharing feature on the device to prevent the arrival of any person to own your files or even open the field to participate to do so, remove the property from the files in the Tools menu Folder Options. 4. If in your private and important files then tightly closed with a password. How easy Compress the files you want protected and in the options you'll find a special option put a password for the file even though the person taking the file from your computer will not be able slot and always use a password consisting of numbers, letters and punctuation and a low of eight characters it difficult to decrypt. 5. There are also programs you place after the files and folders words and also programs. To limit their use. 6. Turn off the wireless network card on your mobile device. It has not been operating mode button on the mobile device messes. But he was placed in order to close it after the completion of use. This will save you a first energy and will prevent other people from entering or even access to your device. 7. If you are working on a wireless network card remove the card from Mahmul. albages some tips to protect: 8. Do not connect to a wireless network and your device does not contain a virus protection program. Once you connect to the wireless network there is the possibility that either infected with HIV or electronic worm within 15 seconds if your computer did not contain the anti-virus software modern IV.
