Stands for "Peer to Peer." In a P2P network, the "peers" are computer systems which are connected to each other via the Internet. Files can be shared directly between systems on the network without the need of a central server. In other words, each computer on a P2P network becomes a file server as well as a client.
The 7 Steps of a Successful Risk Assessment
- Step 1: Identify Your Information Assets.
- Step 2: Identify the Asset Owners.
- Step 3: Identify Risks to Confidentiality, Integrity, and Availability of the Information Assets.
- Step 4: Identify the Risk Owners.
- Step 5: Analyze the Identified Risks and Assess the Likelihood and Potential Impact if the Risk Were to Materialize.
What are the risks of file sharing?
- You could unknowingly give others access to your computer while file sharing, who could potentially copy private files.
- Downloading viruses, malware and spyware to your computer without you knowing it.
In June 1999, Napster was released as an unstructured centralized peer-to-peer system, requiring a central server for indexing and peer discovery. It is generally credited as being the first peer-to-peer file sharing system.
A.what types of malware can be transported through p2p file sharing
- Software viruses.
- Worms.
- Trojan Horse.
- Rootkit malwares.
- Ransomwares.
- Keyloggers.
- Graywares, such as adwares or spywares.
Installing P2P software allows anyone, including criminal hackers, to access your data. This can result in data breaches, credit card fraud and identity theft. pdf.” He would then download tax returns, bank statements, and other sensitive documents and use them to steal identities.
While Network Based Firewall filters traffic going from Internet to secured LAN and vice versa, a host based firewall is a software application or suite of applications installed on a single computer and provides protection to the host. However when it comes larger networks, Host based Firewalls are not enough.
An “Attack Vector” is the industry's term for describing the path that a hacker or a malware application might follow to compromise your data. Your “Attack Surface” is all the publicly and privately-exposed nexus points between your company's data and the human or software-driven interfaces of your company.
Advantage of peer to peer network
- The main advantage of peer to peer network is that it is easier to set up.
- The peer to peer network is less expensive.
- In peer-to-peer networks all nodes are act as server as well as client therefore no need of dedicated server.
Since it is very easy to change the port for these P2P applications it is very difficult to block this traffic. It is strictly not advised to have P2P application allowed in your network. Enterprises should take measures to prevent P2P clients from being installed on any computers on the network.
Characteristics of Peer to Peer Computing
Peer to peer networks are usually formed by groups of a dozen or less computers. These computers all store their data using individual security but also share data with all the other nodes. The nodes in peer to peer networks both use resources and provide resources.The primary goal of peer-to-peer networks is to share resources and help computers and devices work collaboratively, provide specific services, or execute specific tasks. As mentioned earlier, P2P is used to share all kinds of computing resources such as processing power, network bandwidth, or disk storage space.
The two basic LAN models are client-server and peer-to-peer. In a peer-to-peer network, all computers on the network share each other's resources, including disk storage and attached printers.
A peer-to-peer (P2P) economy is a decentralized model whereby two individuals interact to buy sell goods and services directly with each other or produce goods and service together, without an intermediary third-party or the use of an incorporated entity or business firm.
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.
Peer-to-peer (P2P) software provides direct access to another computer. Peer-to-peer software can bypass firewall and antivirus systems by hiding activities of users, such as file transfers. It creates an open channel for malicious code to enter the system.

- The peer to peer network is less expensive.
- In peer-to-peer networks all nodes are act as server as well as client therefore no need of dedicated server.
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 absolute assurance that P2P files are free of malware and not copyrighted. Use P2P file sharing applications at your own risk.
Disadvantages of Peer to Peer Network
- In this network, the whole system is decentralized thus it is difficult to administer.
- Security in this system is very less viruses, spywares,trojans, etc malwares can easily transmitted over this P-2-P architecture.
- Data recovery or backup is very difficult.
However, the most common use case for peer-to-peer networks is the sharing of files on the internet. Peer-to-peer networks are ideal for file sharing because they allow the computers connected to them to receive files and send files simultaneously.
Usually, you can get 3-5 times faster on a peer-to-peer architecture than on client-server. Another issue is distributing build within a single office from a central server. As we discussed above, a peer-to-peer approach is better when many clients need access to the data.
Wi-Fi Direct (also known as peer-to-peer or P2P) allows your application to quickly find and interact with nearby devices, at a range beyond the capabilities of Bluetooth. The Wi-Fi peer-to-peer (P2P) APIs allow applications to connect to nearby devices without needing to connect to a network or hotspot.
20 Best Peer to Peer (P2P) File Sharing Programs
- uTorrent. The little and lightweight downpour customer accessible for Windows, Mac, Linux and Android cell phones, uTorrent tops the rundown of document sharing project.
- BitTorrent. This is one of best, speediest, safe and generally utilized p2p program.
- Soulseek.
- Shareaza.
- eMule.
- KCeasy.
- Ares Galaxy.
- WinMX.
Peer-to-peer networks can be as small as two computers or as large as hundreds of systems and devices. Although there is no theoretical limit to the size of a peer-to-peer network, performance, security, and access become a major headache on peer-based networks as the number of computers increases.
Most people pay no income tax, because peer-to-peer lending is included in the Personal Savings Allowance. You pay tax at your own income-tax rate on any interest earned above the savings allowance.
Because, unlike depositors in banks, peer-to-peer lenders can choose themselves whether to lend their money to safer borrowers with lower interest rates or to riskier borrowers with higher returns, in the US peer-to-peer lending is treated legally as investment and the repayment in case of borrower defaulting is not
