abstract
Some history of networking is included, as well as an introduction to TCP/IP and internetworking. We go on to consider risk management, network threats, firewalls, and more special-purpose secure networking devices. This is not intended to be a frequently asked questions” reference, nor is it a “hands-on” document describing how to accomplish specific functionality.
It is hoped that the reader will have a wider perspective on security in general, and better understand how to reduce and manage risk personally, at home, and in the workplace. Network security is a complicated subject, historically only tackled by well-trained and experienced experts.
However, as more and more people become “wired”, an increasing number of people need to understand the basics of security in a networked world. This document was written with the basic computer user and information systems manager in mind, explaining the concepts needed to read through the hype in the marketplace and understand risks and how to deal with them.

CHAPTER ONE
1.0 Introduction
In certain cases, it might be possible for the attacker to see or redirect the response to his own machine. The most usual case is when the attacker is spoofing an address on the same LAN or WAN. Hence the attackers have unauthorized access to computers.
the basic protocol for sending data over the Internet network and many other computer networks is the Internet Protocol (“IP”). The header of each IP packet contains, among other things, the numerical source and destination address of the packet.
The source address is normally the address that the packet was sent from. By forging the header so it contains a different address, an attacker can make it appear that the packet was sent by a different machine. The machine that receives spoofed packets will send a response back to the forged source address, which means that this technique is mainly used when the attacker does not care about the response or the attacker has some way of guessing the response.
1.2 STATEMENT OF PROBLEM
Network administrators face many threats from both inside and outside the walls of their infrastructure. This paper discusses the risks that everyone faces along with ways to mitigate the exposure and resulting damage from such an attack. It will also focus on new devices being produced to provide increased security.
Despite their slipping market share in router sales to Juniper, Cisco remains the largest provider of Routers, which are used to provide the backbone for the majority of companies today [10]. Because of the large role Cisco routers play in the infrastructure of the internet and the nature of the protocols these routers use; it has placed a large target on them from hackers wanting to exploit these vulnerabilities.1.3 PURPOSE OF STUDY
In order to protect our computers from the network security threats that it is exposed to, we need to first understand the different types of threats that exist, only then we will be able to safeguard our computer. The most common kind of network security threats that computers are exposed to, are the threat of “Viruses”.
It is important to know that a virus is usually sent as a downloadable attachment which is in the form of an executable file. Once a person downloads a file and runs it, that’s when the problem starts. The moment the executable file is “run” the computer gets affected by the network security threats and a virus has now been downloaded by the user.
1.4 IMPORTANCE OF STUDY
Local area networks (LANs) have become a major tool to many organizations in meeting data processing and data communication needs. Prior to the use of LANs, most processing and communications were centralized; the information and control of that information were centralized as well. Now LANs logically and physically extend data, processing and communication facilities across the organization
