Detecting Wireless LAN MAC Address Spoofing Abstract An attacker wishing to disrupt a wireless network has a wide arsenal available to them. Many of these tools rely on using a faked MAC address, masquerading as an authorized wireless access point or as an authorized client. Using these tools, an attacker can launch denial of service attacks, bypass access control mechanisms, or falsely advertise services to wireless clients. This presents unique opportunities for attacks against wireless

article provides all the problems and methods for increasing the throughput in multihop networks by changing the MAC layer and enhancing it with IP packet forwarding and routing. In a wireless network packet forwarding involves reception in wireless interface, transfer of packet to IP layer where next hop IP and MAC address is determined using routing lookup. The current 802.11 DCF MAC either receives or transmits a packet but does not forward a packet (receiving and transmitting in the same interface)

INTRODUCTION Ethical hacking and ethical hacker are terms used to describe hacking performed by a company or individual to help identify potential threats on a computer or network. An ethical hacker attempts to bypass system security and search for any weak points that could be exploited by malicious hackers. This information is then used by the organization to improve the system security, in an effort to minimize or eliminate any potential attacks. For hacking to be deemed ethical, the hacker

A large LAN can accommodate thousands of computers. LAN divided into logical groups called subnets. LAN is divided by two: wired LAN and wireless LAN. The differences in terms of: - the medium impacts the design. - stations are mobile. - different MAC. - wireless LAN is cheaper to install and maintain. Single Building LAN Multiple Building LAN <>THE TECHNOLOGY’S APPLICATION<> What is use of LAN? LAN is used to share resources such as files, printers, games

An IP address serves two principal functions; host or network interface identification & location addressing. Its role has been characterized as follows: A name indicates what we seek. An address indicates where it is. A route indicates how to get there.The designers of the Internet Protocol defined an IP address as a 32-bit number & this system, known as Internet Protocol Version 4 (IPv4), is still in use today

be used as a "backdoor" into a network to stage an attack. This paper reviews some of the tactics used in wireless LAN network discovery and attempts to identify some of the fingerprints left by wireless LAN discovery applications, focusing on the MAC and LLC layers. This fingerprint information can then be incorporated into intrusion detection tools capable of analyzing data-link layer traffic. Introduction The growth of 802.11 networks has been met with the development of several wireless

high energy comsumption, but TMMAC instead needs only a single half-duplex radio transceiver on each node that the hardware cannot transmit and receive simultaneously, but can swtich the frequency dynamically. The two-dimension negotiation enables the MAC protocol to overcome the multiple channels advantage and produces better performance than IEEE 802.11. In addition to conventional frequency negotiation, this protocol also introduces lightweight explicit time negotiation.\ indent Since the time in

1.0 INTRODUCTION LAN (Local Area Network) is a connection that connected computer in certain area like school, laboratory, or office building. LANs usually connect workstations and personal computers. Each computer or called ‘node’ could access data anywhere on the LAN. For example, we could share network printer in the LAN computer network. LAN also used as a communication tool for user to communicate each other in the range of the network. 2.0 PROBLEM STATEMENT In a small LAN which consist of

Any network can be used with the module that supports TCP/IP and connecting to an Internet router enables communication to any Internet enabled device. Other supported protocols include ARP, BOOTP, DHCP, and ICMP. The MAC address is pre-assigned on every device, but the IP address can be assigned either fixed using EEPROM commands or dynamic from a DHCP server using the BOOTP protocol. Each module includes three 8-bit ports with twenty-four digital input/output signal lines which can be configured

example of IP addresses and how they are structured in their range is good to use. Machines are on the same network wire, but on separate networks which is what coins the term logical network. If there are IP address ranges such as 231.41.xx.x for approximately 20 machines, and IP address ranges such as 232.42.xx.x for 20 different machines, they are connected to the same network backbone but are on separate logical networks or in other words, have separate IP networks. The workstations on the

forwarding decisions. In addition, you will learn how devices on local-area networks (LANs) use Address Resolution Protocol (ARP) before forwarding data to a destination. You will learn what happens when a device on one network does not know the MAC address of a device on another network. You will learn that Reverse Address Resolution Protocol (RARP) is the protocol a device uses when it does not know its own IP address. Lastly, you will learn the difference between routing and routed protocols and how routers

you can see, the Physical address of the Wireless LAN adapter in all three cases is F4-B7-E2-F1-74-57 and also the Physical address of the Ethernet Adapter in both the cases is 3C-97-0E-91-C8-12. But the IP address is different. It is 10.0.0.57 for Comcast, 192.168.43 for Mobile Hotspot and 172.25.207.42 for UHSECURE WIFI. So, it is clear that IP addresses are Network specific while MAC addresses are device specific. Now, “Why do we need both IP address and MAC address to a Single device?” We analyze

TCP, or transmission control protocol, is one of the most fundamental aspects of guaranteed information transfer on the Internet. As the fourth layer in the OSI model, the TCP protocol ensures that all data sent from one IP address is, in fact, received by another IP address. If a packet did not make it the recipient IP, TCP would call for the packet to be sent again, until confirmation of reception. It is due to these reasons that TCP grants the user the capability of providing stream based transfer

The Struggle of Women in Lowell’s Patterns and Sorrell’s From a Correct Address "Woman is not born," feminist Andrea Dworkin wrote. "She is made. In the making, her humanity is destroyed. She becomes symbol of this, symbol of that: mother of the earth, slut of the universe; but she never becomes herself because it is forbidden for her to do so." Dworkin’s quote relates to women throughout history who have been forced to conform. Although women can be regarded highly in society, representing

phones, storage purposes such as storing music on a CD or for social purposes such as email. E-mail The first thing I will look at will be email. With email you can quickly talk to friends, work colleagues, basically anyone who has an email address. I have two email accounts, one at home provided by hotmail, which is useful because I can log-on to it anywhere via the Internet. I also have one at school provided by Solihull L.E.A, which I can only access at school; both have a unique log-on

Resource Locator;” an Internet Address. Each user on the Internet is identified by a unique IP address, consisting of four bytes (or 32 bits) from 0 to 255 separated by periods, such as 132.112.15.254. To avoid remembering such an unwieldy address, a domain name is used instead. When you type a domain name into your browser, it first looks it up in a “domain name server” or DNS, which is like a registry or telephone book that associates the name with the correct IP address. What are the parts

December 7th, 1941- a date which will live in infamy- the United States of America was suddenly and deliberately attacked by naval and air forces of the Empire of Japan” (1). These are the words Franklin Delano Roosevelt chose to begin his Pearl Harbor Address to the Nation the day after Pearl Harbor was attacked by Japan. FDR’s speech was a call to arms, and in his speech he expressed outrage towards Japan and confidence in inevitable triumph. The speech was a request to declare war against Japan and

Multinational organisations, defined as organisations with operations, subsidiaries or investments in more than two countries, are becoming more commonplace as the concept of globalisation and the global economy becomes more widespread in practice. It is evident that the globalisation phenomenon has dramatically advanced in the last twenty years, as globalisation is a more advanced form of internationalisation; which includes the connection of various practices within organizations and countries

'how do you solve problems to do with health and safety? Are there any issues you feel strongly about and feel something should be done?' she replied 'I believe health and safety is very important and my workplace feels the same and are keen to address and problems'. I then wanted to know 'if any health and safety issues affected her personally on an everyday basis and what was done about them?' she replied ' no I don't have any they affect me on a day to day basis' Next I wanted to know

Damsels in Address It is clearly evident that many fairy tales of childhood tend to shape the reader. Certain moral codes and ideals are tightly woven into the text of many fairy tales, promoting or denoting a character’s actions. In the Grimm’s fairy tales Cinderella, Brier Rose, and Rapunzel, the heroines of these tales exhibit strong behavioral codes, thus providing opportunity for the young female reader to relate to the damsel, or to model herself to behave in a similar fashion. In accordance
