1) Eavesdropping: It can be defined as secretly listening to the private conversation of others without their consent. Here an attacker can choose to passively eavesdrop on the network communication and steal the data. Through passive eavesdropping attackers apparently eliminate their presence in the network and make such attacks difficult to detect. The goal of such an attack is to violate the confidentiality of the communications by intercepting the network and sniffing or listening to the routing packets. Also, an adversary can actively influence the communication channel by disrupting, jamming or modifying the network packets and/or inserting false packets into the network. Jamming happens at physical layer which can cause intermission and make the communication impossible. Using a strong encryption and decryption technique one can obtain strong protection against eavesdropping. Proper authentication and integrity mechanisms can also be useful. On the other hand, a standard defense against jamming includes various forms of spread-spectrum and frequency-hopping communications and maintaining a low-duty cycle, locating a jamming area, and rerouting transmissions. 2) Denial of Service: Dos is an attack where the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or…

A Home Area Network is an interconnection in which any networking apparatuses are accompanied with each alienation for allocating assets between them with the agency of internet. The central advantage of Home Area Network is that you bag allocate abnormal arrange of content i.e. videos, audios etc. among abnormal consumers. A computer with ample storage memory can be applied as server which can be adroitly accessed by the clients along with users can efficiently approach the data whenever they…

Technology Framework Design In this section, we combine the user domain needs described in Part 1 of this proposal, the physical framework requirements described in Part 2, and the technology selections described in Part 3 to create the final Digital Edge Manufacturing network infrastructure proposal. Choosing the Cabling Used in the Network We considered infrastructure costs, speed, and reliability for cabling and adaptors. Our network employed hybrid type of network sine we use Ethernet cable,…

Their machines could be infected by a virus, which they bring back onto campus,” said Dore. “Through Network Sentry we now force them to keep their machines fully updated, which effectively eliminates viral outbreaks.” “Network Sentry’s built-in scanning system, which includes a check for viruses as well as Windows patches, made it very easy for us to require updates and secure computers we don’t own. It’s a great help because it forces the user to update or risk losing network access. They…

Verizon’s Vision, Mission, and Strategic Objectives: Verizon Wireless (NYSE: VZ, www.verizon.com) is the largest provider of wireless products and services in the United States of America with 114.2 million subscribers [1]. Verizon Wireless was founded on June 30, 2000 when telecommunications giants Bell Atlantic Corp. and GTE Corp completed a nearly 65 billion dollar merger and are currently headquartered in Basking Ridge, NJ [2]. Verizon Wireless currently employs over 162,000 employees…

Adair and Peterson found out that these technologies have higher radiation levels more than the naturally occurring radiation from the sun. In their opinion, no radiation higher than the sun is healthy. This is an indication of the potential cause of cancers that are on the rise. A causative relationship has not been conclusively established. Annotated 2 Gortmaker, S.L., Must, V., Sobol, A. M. et al. (1996). Television Viewing as a Cause of increasing Obesity among Children in the United…

The history of computing technology can be organized into four distinct generations, each defined by a distinct transformation in technological innovation. The first generation stretched from 1947-1957, and is identifiable by its use of vacuum tube technology. This generation transitioned into the second generation during the late 1950’s with the use of transistors. Subsequently in the 1960’s the third generation began, classified by its use of integrated circuits. The fourth generation of…

1. INTRODUCTION Figure: Wi-Fi logo Wi-Fi stands for wireless fidelity. Wi-Fi is the wireless network that used to connect the internet without wires. It’s based upon the radio technology. Many computers can be connected to each other through Wi-Fi and we can share files data and many of the other things through Wi-Fi. A Wi-Fi network operated just like a wired network, but without the restriction of wires, it not only enable user to share the data but it also provide easy connection to the…
