During the 18th century when Western powers invaded China, the Chinese troops were still using flintlock rifles and cannons. At the end of the 14th century a Chinese named Wan Hu fitted a chair with 47 prototype self-made rockets and held a large kite in his hands. His plan was to fly into space and then float back down to the Earth using the kite. The rockets ended up exploding and killing Wan Hu but in his honor In the 1970s, the International Astronomical Union named a lunar crater after Wan to commemorate the first person who attempted to fly using rockets.

...An ISS Technical White Paper Wireless LAN Security 802.11b and Corporate Networks 6303 Barfield Road · Atlanta, GA 30328 Tel: 404.236.2600 · Fax: 404.236.2626 WWireWireless Lan Security 802.11b Wireless LAN Security Introduction Although a variety of wireless network technologies have or will soon reach the general business market, wireless LANs based on the 802.11 standard are the most likely candidate to become widely prevalent in corporate environments. Current 802.11b products operate at 2.4GHz, and deliver up to 11Mbps of bandwidth – comparable to a standard Ethernet wired LAN in performance. An upcoming version called 802.11a moves to a higher frequency range, and promises significantly faster speeds. It is expected to have security concerns similar to 802.11b. This low cost, combined with strong performance and ease of deployment, mean that many departments and individuals already use 802.11b, at home or at work – even if IT staff and security management administrators do not yet recognize wireless LANs as an approved technology. This paper addresses the security concerns raised by both current and upcoming 802.11 network technologies. Wireless LAN Business Drivers Without doubt, wireless LANs have a high gee-whiz factor. They provide always-on network connectivity, but don’t require a network cable. Office workers can roam from meeting to meeting throughout a building, constantly connected to the same network resources enjoyed by wired...

...Topic 1 a) Discuss any 3 key skills and characteristic should an information system manager posses. b) Today’s Point of Sales – Electronic Fund Transfer (POS-EFT) system requires several components to function. List and discuss the function for these components. a) An Information System (IS) manager has two principle roles within an organization. He has to be able to manage the change processes that are inevitably initiated by the introduction of technology into his workplace, and he has to manage the operational aspects of business and organizational activities founded on computing and communication technology. Hence an IS manager is a leading figure in both organizational change and performance. From this definition, it is a natural deduction that for IS manager to work effectively, they must have or need to be: * Detailed knowledge of the organization’s mission and vision, its peculiar business strategies and implementation skills. With these understanding, the IS manager will then be able to design an information system which can help the organization to achieve its goal. * Skilled in inter-personal management. This consists of communication skills both written and oral, people oriented and also negotiation skill. Regardless of how an organization structures its information system department, system development is a team effort. So learning how to work and communicate effectively with other team members is important for any information system professionals...

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...

...| Network Administrator | Memo To: John Smith From: Felix Pino CC: Richard Pierce Date: 4/27/2015 Re: Site Survey Benefits Dear Sir, It has come to my attention that we have not been allocated time and money to do a proper site survey. I feel this is a detrimental path for your new system. A site survey is the precursor to a successful wireless network implementation. Like with many things, upfront planning and documentation facilitates the smooth deployment of the new network. With a site survey an engineer completes the physical check and identifies the best locations for the wireless access points, then creates a site report. The throughput of the access points is then fine-tuned using specialized training of those doing the evaluation. The final report will include a hardware list, where to install the products, the configuration of the devices, and suggestions for antenna placement for each device. All of these things can and will save the company money in the long run. Some of the things that can go wrong without a proper site survey are not getting optimal performance from our new network, over purchasing of equipment or under purchasing of equipment, not getting full coverage inside the buildings, potential interference that you would not know about beforehand, unauthorized access to your network and so on and so forth There are three types of tools needed for a site survey, wireless tools, measurement tools, and documentation tools. Wireless tools are such...

Protecting Wireless LANs…………………………………………...13 V. Wireless LAN Security Summary……………………………………18 I. Introduction a. The 802.11 Wireless LAN Standard In 1997, the IEEE ratified the 802.11 Wireless LAN standards, establishing a global standard for implementing and deploying Wireless LANS. The throughput for 802.11 is 2Mbps, which was well below the IEEE 802.3 Ethernet counterpart. Late in 1999, the IEEE ratified the 802.11b standard extension, which raised the throughput to 11 Mbps, making this extension more comparable to the wired equivalent. The 802.11b also supports the 2 Mbps data rate and operates on the 2.4GHz band in radio frequency for high-speed data communications As with any of the other 802 networking standards (Ethernet, Token Ring, etc.), the 802.11 specification affects the lower layers of the OSI reference model, the Physical and Data Link layers. The Physical Layer defines how data is transmitted over the physical medium. The IEEE assigned 802.11 two transmission methods for radio frequency (RF) and one for Infrared. The two RF methods are frequency hopping spread-spectrum (FHSS) and direct sequence spread-spectrum (DSSS). These transmission methods operate within the ISM (Industrial, Scientific, and Medical) 2.4 GHz band for unlicensed use...

...convenient access for customers and other users. WLAN provides users many benefits such as portability, flexibility, reduced hardware need and lower installation cost. Without a doubt, the benefits of WLAN enhance an organisation’s overall productivity. However, WLAN is not without its own security problems. WLAN infrastructures that are not secured would actually affect the security posture of the LAN environment as well. Having an unsecured WLAN can result in a loss of service, or can be used as a staging area to launch attacks against other networks. The significant challenges faced today in securing wireless LANs are maintaining privacy, data confidentiality, and preventing unauthorized access using proper access control mechanisms. This paper will mainly focus on the wireless access points (APs) as devices that act as a central transmitter and receiver or WLAN radio signals. It will begin by introducing the concept of WLAN. The introductory section gives brief information on the WLAN components and its architecture. In order to examine the WLAN security threats and vulnerabilities, this paper will look at Rogue APs, Ad-Hoc Networks, MAC Spoofing, Honeypot APs and Denial of Service.

...Reis Barrie Research Paper CNT4514 Wireless Vulnerabilities The world of wireless networks as we all know is one of the most rapidly growing areas in our world today. With the massive amount of data that is going on, “the cloud” the security of all of our data is questioned. As well with so many of our day to day tasks relying on our wireless capabilities it make you wonder how safe is it to rely so heavily on something. We have to ask the questions what are the key vulnerabilities of wireless networks and even just of networks in general. Different types of networks have different levels of safety and it is a good idea to know not only which are safe but the vulnerabilities of said networks to keep our information out of the wrong hands and keep our day to day life moving as smoothly as possible. Unlike wired LANs the wireless LAN users are not restricted to the physical area of a wired system. While this may feel beneficial to the user it is also very beneficial to sniffing and eavesdroppers who are listening to the radio waves that are broadcasted through the air. Intercepting these packets they can pick up messages that may contain sensitive information. Seeing how the range of a wireless LAN can extend beyond the building the eavesdroppers don’t even need to be inside the building. A simple thing you can do is open up your wireless adapter on your computer and see how many open wireless networks are around you. From my house I currently have 4 open wireless networks...
