Elements of Network Security Louis Kibby Network / Datacom I TCM 537 Mr. Stuart Sandler November 28‚ 2005 Elements of Network Security Introduction The primary objective of a network security system is to‚ in a cost effective manner‚ balance convenient access to legitimate users and inaccessibility to attackers. In a nutshell‚ the goal is to prevent connectivity to anyone intending to cause harm to the network. The harm to which this paper refers can come in the following forms: 1. Application-level

1. Frequency Division Multiplexing Frequency Division Multiplexing is a technique that can be applied when bandwidth of the link is greater than combined bandwidth of signals to be transmitted. Frequency Division Multiplexing technique is the process of translating the frequency of individual channel into per-assigned frequency slots within the bandwidth of the transmission medium. Different carries frequencies are assigned to different users. We can use any modulation scheme to assign carrier

Kirchhoff’s Law Kirchhoff’s current law (KCL) imposes constraints on the currents in the branches that are attached to each node of a circuit. In simplest terms‚ KCL states that the sum of the currents that are entering a given node must equal the sum of the currents that are leaving the node. Thus‚ the set of currents in branches attached to a given node can be partitioned into two groups whose orientation is away from (into) the node. The two groups must contain the same net current. In general

Millions of teens participate in social networks. According to the 1997 Pew Research report Teens and Social Media‚ 93 percent of teens are active online. Fifty-five percent have created a profile on a social networking site. What are teens doing on these sites? Why are they spending so much time connecting with others online? HANGING OUT MOVES ONLINE Ask teens what they do on social networking sites and chances are their answer will be "just hang out." In fact‚ hanging out with friends is nothing

Chapter 1 1. INTRODUCTION Artificial Neural Networks are being touted as the wave of the future in computing. They are indeed self learning mechanisms which don ’t require the traditional skills of a programmer. But unfortunately‚ misconceptions have arisen. Writers have hyped that these neuron-inspired processors can do almost anything. Fig. 1.1 Neural Network These exaggerations have created disappointments for some potential users who
