Introduction to Network - Course 15

10.1.2.5 Lab - Researching Peer-to-Peer File Sharing


Lab - Researching Peer-to-Peer File Sharing
Objectives
Part 1: Identify P2P Networks, File Sharing Protocols, and Applications
Part 2: Research P2P File Sharing Issues
Part 3: Research P2P Copyright Litigations
Background / Scenario
Peer-to-peer (P2P) computing is a powerful technology that has many uses. P2P networks can be used to share and exchange files, and other electronic materials.
The use of P2P networks to upload, download, or share copyrighted material, such as movies, music, and software, can violate the rights of copyright owners. In the P2P file-sharing context, infringement may occur when one person purchases an authorized copy and then uploads it to a P2P network to share with others. Both the individual who makes the file available and those making copies may be found to have infringed the rights of the copyright owners and may be violating copyright law.
Another problem with P2P file sharing is that very little protection is in place to ensure that the files exchanged in these networks are not malicious. P2P networks are an ideal medium for spreading malware, such as computer viruses, worms, Trojan horses, spyware, adware, and other malicious programs.
In this lab, you will research available P2P file sharing software and identify issues that can arise from the use of this technology.

Device with Internet access
Part 1:     Identify P2P Networks, File Sharing Protocols, and Applications
In Part 1, you will research P2P networks and identify popular P2P protocols and applications.
Step 1:     Define P2P networking.
a.     What is a P2P network?
____two or more computers connect over a network and share resources without having a dedicated server________________________________________________________________________________
____________________________________________________________________________________
b.     Identify at least two advantages that P2P provides over client-server architecture.
____ In P2P networks, clients provide resources, which may include bandwidth, storage space, and computing power. This property is one of the primary advantages of using P2P. As nodes arrive and demand on the system increases, the total capacity of the system increases and the likelihood of failure decreases. If one peer on the network fails to function properly, the whole network is not compromised or damaged. In contrast, with a typical client–server architecture, clients share their demands with the system but not their resources. In this case, as more clients join the system, fewer resources are available to serve each client. If the central server fails, the entire network is taken down. The decentralized nature of P2P networks removes the single point of failure that can be inherent in a client server  based system. _____________________________________________________________________________

c.     Identify at least two disadvantages of P2P networks.
______ A P2P network is decentralized, which makes it difficult to administer. ______________________________________________________________________________
____________________________________________________________________________________
Step 2:     Identify P2P file sharing protocols and applications.
a.     Identify at least two P2P file sharing protocols used today.
_ Ares, BitTorrent, Direct Connect, FastTrack, eDonkey, Gnutella, MANOLITO/MP2PN
____________________________________________________________________________________
____________________________________________________________________________________
b.     Identify at least two popular P2P file sharing applications available today.
Many Gnutella client applications are available, including gtk-gnutella, WireShare, Shareaza, and Bearshare._____________________________________________________________________
____________________________________________________________________________________
c.     What P2P file sharing protocol is attributed to producing the most P2P traffic on the Internet today?
_____ most of the P2P traffic is likely from BitTorrent._ Today BitTorrent was utilized by 150 million active users______________________________________________________________________________
Part 2:     Research P2P File Sharing Issues
In Part 2, you will research P2P copyright infringement and identify other issues that can occur with P2P file sharing.
Step 1:     Research P2P copyright infringement.
a.     What does the acronym DMCA stand for and what is it?
_________ The Digital Millennium Copyright Act (DMCA) is a United States copyright law that implements two 1996 treaties of the World Intellectual Property Organization (WIPO). It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures (commonly known as digital rights management or DRM) that control access to copyrighted works.___________________________________________________________________________
____________________________________________________________________________________
____________________________________________________________________________________
b.     Name two associations that actively pursue P2P copyright infringement?
____________________ The Recording Industry Association of America (RIAA) and the Motion Picture Association of America (MPAA) have instituted legal actions against a number of P2P file sharing sites and individuals.________________________________________________________________
____________________________________________________________________________________
c.     What are the penalties for copyright infringement?
____________ Penalties, both civil and criminal, can be severe. Civil penalties may include actual damages and profits, or statutory damages (maximum amount of $30,000 per work that is infringed). The court can also award reasonable attorney’s fees and costs and increase the damages in the case of willful infringement (maximum amount of $150,000 per work that is infringed). Criminal penalties can include fines and imprisonment.________________________________________________________________________
____________________________________________________________________________________
____________________________________________________________________________________
d.     What are the file sharing copyright laws in your area? Are they more strict or less strict than those in other areas of the world? How aggressively do enforcement agencies in your area pursue those who share copyrighted material?
__________Vary Depends on local settings.________________________________________________________________________
____________________________________________________________________________________



Step 2:     Research other P2P issues.
a.     What types of malware can be transported through P2P file sharing?
_______ adware, computer viruses, spyware, Trojan horses, and worms._____________________________________________________________________________
____________________________________________________________________________________
b.     What is Torrent poisoning?
___ Torrent poisoning is the act of using the BitTorrent protocol to intentionally share corrupt data or data with misleading file names. _________________________________________________________________________________
____________________________________________________________________________________
c.     How could identity theft occur through the use of P2P file sharing?
________ If the P2P client software is incorrectly configured, it may provide access to the personal information and files stored on your computer.____________________________________________________________________________
____________________________________________________________________________________
Part 3:     Research P2P Copyright Litigations
In Part 3, you will research and identify historical legal actions that have occurred as a result of P2P copyright infringement.
a.     What was the first well-known P2P application that specialized in MP3 file sharing and was closed by court order?
____________ Napster was originally released in 1999 and then closed by court order in July 2001. It was co-founded by Shawn Fanning, John Fanning, and Sean Parker. At its peak, there were 25 million users, 80 million songs, and the system never crashed.________________________________________________________________________
b.     What was one of the largest P2P file sharing lawsuits ever?
___________________ In May of 2011, the law firm Dunlap, Grubb, and Weaver (U.S. Copyright Group) sued 24,583 BitTorrent users for sharing the film titled “Hurt Locker.” The case was the largest BitTorrent lawsuit._________________________________________________________________
____________________________________________________________________________________
Reflection
How can you be sure that the files you are downloading from P2P networks are not copyrighted and are safe from malware?

___________ There is no firm assurance that P2P files do not contain malware and are not copyrighted. Use P2P file sharing applications at your own risk.____________________________________________________________________________
