Thesis statement: Users of Peer to Peer networks must be aware of the security and how to deal with the attacks.
Introduction
Technologies are getting more advance each day, in this assignment will be sharing and discuss about the security in peer to peer networks. Security run an important role in every network applications because this is the place where people and the systems are all link up together and can access each other data and also programs. According to Madron (1992) points out that:
One of the primary objectives of computer networks (and especially of local area networks) is to provide easy and convenient access to computer systems within an organizations, and it is that same ease of use that can sometimes conflict with security needs. (p.3)
This being the case most of the peer to peer networks can remote the systems to access the nodes in the peer to peer network and programs are often transferred in the systems in remote locations and also because of the usefulness of the networking it really attracts people all around to use and at the same time problems of security happens. So it is crucial for the users to ensure their security in the networking. The problems usually started from modification of messages in transit, denial of services attacks and interception of messages, “perhaps the most obvious active threat faced by a communication system is an attack that can destroy or delay most or all messages” (Madron, 1992, p.63). In order to secure the systems of peer to peer network there is three basics requirements of security, integrity and authentication, it seems evident that “Data integrity ensures that data have not been altered or destroyed in an unauthorized manner. Both data integrity and authentication rely heavily on encryption as a primary security mechanism” ( Madron, 1992, p.71). For this security the operating system level and application level is used. As to ensure the security for every users, the helps support security needs to be posted to the peer to peer network and also to be specified.

Peer to peer (P2P) file sharing networks have become wildly popular. The first major file-sharing network example was NASPSTER, which designed to allow music fans to share MP3 music files and so on. P2P actually is all about sharing resources like files, storage or processing time, with ev...

...In the end, the use of technology is probably the only way we can secure information. The investment in information that individuals and organizations have made, are making, and will make in the future is enormous, however, and security systems aid us in protecting that investment.” (p.235). Aware of the security and protection.

Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
A network can be based on either a peer-to-peer level or server-based, also referred to as domain-based. To distinguish the difference, a peer-to-peer network, also known as a workgroup, is a network in which a group of computers are connected together to share resources, such as files, applications, or peripherals. The computers in a peer-to-peer network are peers to one another, meaning no single computer has control over one another. There is also no central location for users to access resources, which means that each individual computer must share their files in order for other computers to have access (Muller, 2003, p.411). “In a peer-to-peer environment, access rights are governed by setting sharing permissions on individual machines.” (Cope, 2002) On the other hand, in a domain-based network, the computers connected together are either servers or clients. All of the other computers connected to the network are called client computers. The server is a dedicated machine that acts as a central location for users to share and access resources. The server controls the level of authority each user has to the shared resources. When logging on to the network, users on client machines are authenticated by the server, based on a user name and password (Lowe, 2004, p.13).

The computer is considered one of the most important technological advances of the twentieth century. Security and privacy issues have been in existence long before the computer became a vital component of organizations' operations. Nevertheless, the operating features of a computer make it a double-edged sword. Computer technologies with reliable error detection and recording capabilities, permit the invasion of a supposedly secure environment to occur on a grand scale and go undetected. Furthermore, computer and communications technology permit the invasion of a persons' privacy and likewise go undetected. Two forces threaten privacy: one, the growth of information technology with its enhanced capacity for surveillance, communication, computation, storage and retrieval and two, the more insidious threat, the increased value of information in decision making. Information has become more vital in the competitive environment, thus, decision makers covet it even if it viol!
Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
Peer-to-peer is a communications model in which each party has the same capabilities and either party can initiate a communication session. Other models with which it might be contrasted include the client/server model and the master/slave model. In some cases, peer-to-peer communications is implemented by giving each communication node both server and client capabilities. In recent usage, peer-to-peer has come to describe applications in which users can use the Internet to exchange files with each other directly or through a mediating server.

In this era when the Internet provides essential communication between tens of millions of people and is being increasingly used as a tool for security becomes a tremendously important issue to deal with, So it is important to deal with it. There are many aspects to security and many applications, ranging from secure commerce and payments to private communications and protecting passwords. One essential aspect for secure communications is that of cryptography. But it is important to note that while cryptography is necessary for secure communications, it is not by itself sufficient. Cryptography is the science of writing in secret code and is an ancient art; In the old age people use to send encoded message which can be understand by the receiver only who know the symbolic and relative meaning of that encoded message .The first documented use of cryptography in writing dates back to circa 1900 B.C. Egyptian scribe used non-standard hieroglyphs in an inscription. After writing was invented cryptography appeared spontaneously with applications ranging from diplomatic missives to war-time battle plans. It is no surprise, then, that new forms of cryptography came soon after the widespread development of computer communications. In telecommunications and data cryptography is necessary when communicating in any untrusted medium, which includes any network, particularly the Internet [1].Within the context of any application-to-application communication, there are some security requirements, including:
The first online peer to peer file-sharing application was Napster. Napster allowed people to copy music from their CDs onto their computers in mp3 format. They then allowed other members of Napster to download these songs onto their computers. Once this caught on, millions of people were downloading thousands of songs a day. And as you can imagine, this did not make the record companies happy with the idea that people were getting their music for free instead of buying the CD. It also caused a problem with some of the recording artists. Most notably Metallica.
All around the world people connected to the internet are downloading free digital content through P2P file sharing software.
Peer-to-peer (P2P) is a substitute network design to the conventional client-server architecture. P2P networks utilize a decentralised model in which each system, act as a peer, and serve as a client with its own layer of server functionality. A companion plays the role of a client and a server in the meantime. That is, the node can send calls to other nodes, and at the same time respond to approaching calls from other companions in the system. It is different from the traditional client-server model where a client can just send requests to a server and then wait for the server’s response.
Personal Development is a lifelong process that involves the assessment of current skills and talents and the enhancement of oneself based on that assessment which then leads to the realization of goals and an improved quality of life. To be able to assess yourself, you need to be able to reflect on your past which helps you to understand the attitudes you have developed and the foundation that you will be building your life on. Also, you have to reflect on your present to see if there’s room for improvement and reflect on your future so that you can achieve your aspirations.
The music industry started in the mid 18th century with Wolfgang Amadeus Mozart. Through the decades there has been a great increase in this industry; however, the revenues for this industry have declined by half in the last 10 years. This has been caused by music piracy, which “is the copying and distributing of copies of a piece of music for which the composer, recording artist, or copyright-holding record company did not give consent” . After 1980’s, when the Internet was released to public, people started to develop programs and websites in which they could share music, videos, and information with...
With the popularity of the Internet, sales for CDs, DVDs, Movies, and many other products have increased. Along with the increase of sales has brought forth an ever increasing problem of illegal media being downloaded. Programs such as Bittorent, Kazaa, and other direct-connect networking programs have allowed the transferring of such illegal media. Downloading song files from the Internet over a free peer to peer network is the moral equivalent of shoplifting music CDs from the local mall.
