Abstract
End of the twentieth century and the beginning of twenty-first century has marked a great advancing period in technological world, especially Internet. Internet has allowed users around the world to communicate with each other very quick and fast. And with the development of Wi-Fi, these communication methods have been even more available. But Wi-Fi also brings its disadvantages with it since potential hackers can access the network faster than wired networks. In this research paper, our team has put forward a goal to observe and find information about the communications ways through the internet and how to improve the security of a wireless network. During our research our team members carefully researched and practiced all those communication methods. Our goal was to evaluate the best ways of communication. Our team members have also learned the threats that could affect Wi-Fi. Our next goal was to prevent all of those threats, to find security measures and evaluate which security measure would work the best. In order to experiment the Wi-Fi and its security we have taken a hotel in Djizak City, Afrosiyob Hotel, which has been opened in July, 2012 and does not have Wi-Fi system. We will implement a Wi-Fi network and we will suggest security measures for the network and propose our plan to the owner, Mr. Jahon Isakov.
Introduction
Since the invention of Internet, it has had numerous uses, from data analysis to communication, from entertainment to education and so on. This proves the importance of internet in today’s world. As technology is ever developing thing, there was no doubt that we would eventually move on from wired networks to wireless ones. Wi-Fi, short for Wireless Fidelity has emerged into our lives and now Wi-Fi hot spots became the first thing we need to know if they have it in restaurants or not. Wirelessly connecting to internet has given us the opportunity to be connected to the internet all the time everywhere. Internet’s most useful side is that it allows users to communicate. Of course there are various methods of communication over the Internet and each person chooses the best fit one for themselves. Each communication method has its own use and has weaknesses too.

With Wi-Fi becoming available in a lot of places and even homes and businesses, restaurants, to secure the wireless network has posed problems to many network users and owners. With various ways of breaking in into a network being developed by hackers, one would have to take few steps to insure the security of a network. The types of threats vary, thus types of security measures have to be used differently. Our potential client, Mr. JahonIsakov of Afrosiyob Hotel will be notified of our project plan and our suggestion, leading to his decision.
Background
We know that Internet has become an important part of our life. We use internet to communicate with friends abroad, to leave comments on their photos, statuses, we use internet to read news, watch movies, and listen to music. Internet’s number one use is it being a great communication tool that has connected billions of people around the world. In present day, internet has broadened our way of thinking to the next level with communication tools such as e-mail, instant chat, video conferencing and web pages. Internet was first developed as a communication tool for United States Army but soon became available to the whole world(Internet, 2012). Since its being made available to public Internet has given us so much, take for example one of the things we can do on Internet. E-mail, Chat or Video Call. A user can log in and see which of his friends or relatives or acquaintances are online and send them messages, talk with them via online phone call or even video talk with them. Also it allows employees in a workplace to talk and discuss matters online without getting up from their seats and going to each other’s offices.
Wireless LANS has made it easy for us to connect to the Internet and communicate, search information and do business even in remote areas. But as everything has its downsides, Wi-Fi is no exception. If wired LANS were a little bit easier to secure since all the cables are physically present and you can control them, wireless networks have no cables thus harder to secure. Wi-Fi faces many threats and improving the security of a wireless network has become the hot topic of today’s technological world.
There are different types of threats to a wireless network, including passive and active attacks. Just to state some of them; Clear Text Traffic which is the basic method for hackers to find out the information, it happens when the message you are trying to send is not encrypted, thus hacker can sniff out your information through data analysis. Next threat is the hacker attacking from a protocol level. In this case a hacker can send out authenticate message to a wireless network use and can disconnect the user from a network. In this case, a network owner may face denial of service and cannot log into his or her own network. The server might have to be reloaded or the password changed.
Afrosiyob Hotel is located in HalqlarDustligi 27, Djizak City, Djizak Region, Uzbekistan. It has been opened in July 2012 and is the first four star hotel in Djizak. However it does not possess Wi-Fi spot and guests were complaining about it. Thus the owner wanted special team to come up with the plan to set up a Wi-Fi system and to make sure that the network will be secure once the wireless network is on. Thus our team has conducted a research on available wireless network providers and the security measures that Afrosiyob manager needs to take in order to prevent from unauthorized access to the network

Recommendation
As we have given examples of ways of communication, it is time to briefly list out some details about these methods. First and easiest form of internet communication is e-mail. This was the first type of communication used since the internet was invented. Once a user would like to send a message to a recipient, he or she would have to type in the message and send it to the relevant mail address and the message will be delivered electronically in minutes of not seconds. If in the first decades it was not possible for you to view your e-mails from any computer, it has become possible with web based e-mails and companies like Microsoft, Yahoo and G-mail are ahead of this game with their free web based e-mail. These companies offer free mail, because they allow advertisers to promote their products and services. If in the beginning only text could be sent by e-mail, now user can attach files and media files to an e-mail and easily send it.
Next communication tool is chatting. This method allows you to have real time, live conversation with another user on a network or online. Chatting can be between two people or between a group of people. With so many chat services available on the internet, a user can download any of these web browsers and chat with their peers. Nowadays, users can actually chat on the web browser itself. In these chat services one can have private chat with a friend or be included in a chat room that is categorized by the hobbies of users like cars, medicine, technology and any other topics a person could imagine. Chatting is not only used by individuals but also at workplaces where employees can discuss work matters.
Internet’s evolution has also brought us video conferencing. You can actually video chat with a person as long as you and the person you are video chatting with have a web cam and a head set with a microphone. While some providers offer this communication method for free, others have monthly subscription fees. Video chat’s main advantage is that users can see each other while speaking, which telephone service lacks.

Current counter measures to Wireless in security 1. Changing the SSID. A wireless STA uses the SSID to find and connect to the wireless network. Since the ways to hide that from an authorized user, the only possible thing you can do is changing SSID so the potential hacker doesn’t make immediate association to your home or company.(Bahadur) 2. Configuring the AP correctly. After changing the SSID, you have to change the default password and SNMP community sting and at the end make sure that all the management interfaces are closed down properly. 3. Do not depend on WEP. Using substitute for WEP such as IPSec, VPN, SSH user can insure that once WEP is broken the hacker will face other obstacles to break into the network 4. Adopting another authorization mechanism. If a user uses 801.1 xs, VPN or certificates to authorize the wireless network users, then hacking in will become harder .This strengthens the security of a wireless network. 5. Segmenting the wireless network. A firewall or similar tools have to be installed in between the AP and the corporate intranet. This method insures that if the hacker broke into network damage is prevented. 6. Preventing physical access. A network owner can use directional antennas on your APS to restrict the directions of the signal.(Chris Weber, 2006)

Discussion
As we have mentioned all the methods of communication over the Internet, individual or a business may prefer one or the other. E-mail is of course the most preferred way of communication by businesses. Employees can send official letters, memos through the Internet. But instant messaging is more preferred by individuals as it allows users to talk fast in real-time. Video calls can be used as an efficient method for international business. Partners around the world can discuss business matter over video call services like Skype.
Security measures we have discussed are all advised by many IT professionals and they work best if they are administered in a proper way and proper place. The first measure that we have mentioned, which is changing the SSID is the most simple way to secure your network since any typical user can do it. If the SSID is changed the potential hacker will not know the network’s name and the password to it. But this method is the most simple, that’s why the easiest to cheat. Hackers have special programs that they use to find the SSID name and they can connect to the network. Next method, configuring the AP is done properly it will secure the network further, thus making it harder for hackers to break in. next method, installing a firewall between the corporate intranet and the AP is another method to secure the wireless network and when hackers will try to break in they will have trouble with it. All these mentioned methods have their own use. If a network owner uses them all with each other and together, the network will be fully secured.
These methods will be used in Afrisoyob Hotel in Djizak, and all the security measures will be used together. As Djizak is developing city in Central Uzbekistan, there are a lot of computer owners who have skills and knowledge in connecting to networks. Thus if security measures are not taken then unauthorized users will be able to connect to the wireless network of the hotel and download illegal material or eat up too much traffic. To avoid additional charges and to not get into legal trouble these security measures have to be taken. (Isakov, 2012)

Conclusion
During our research our team has fully inspected the possibilities of Internet, we have researched all of the methods of communication over the network, we have established that wireless network has more flaws in its security than wired LANS, and we have listed the threats and the ways to secure the wireless network. Our team has decided that if a business would need a communication tool between its employees than the best method is instant messaging. If management wants to send out official letters and memos to its employees, or individuals would like to send messages to each other then e-mail is the best option. If corporates and companies want to have discussions and meeting with each other without the hassles of flying and travelling then free or charged video calling systems are the best method.
In terms of wireless network security, the methods we have mentioned above have carefully been inspected and used by our team members, and we fully recommend all those methods to be used together. The reason for that is, all those methods have their flaws if used alone.
After our suggestion plan to the hotel owner, Mr. Isakov carefully looked through our plan and has agreed to set up a Wi-Fi system with TPS Internet Provider. He will implement all of the security measures we have suggested.
