Peer-to-Peer File-Sharing

Peer-to-Peer (P2P) file sharing is the use of a P2P software for swapping and sharing digital media such as music, films, TV shows, and computer games with others across the internet. P2P file-sharing software is an easy, convenient, and inexpensive way to acquire digital media. However, the process of downloading files and making it available for others to upload from your computer can result in an illegal distribution of copyrighted material, which is a violation of Penn Copyright and Acceptable Use policies, and of the Digital Millennium Copyright Act (DMCA).

P2P File-Sharing Risks

If you are considering P2P File-Sharing software, you need to understand the security and privacy risks associated with it. There are risks associated with using P2P that include:

  • Installation of malicious code (malware). When you are downloading files from P2P applications, it's difficult to verify the source. These applications are often used by malicious individuals to transmit malicious codes incorporated or attached to files. Unknowingly, you could install a virus, spyware or a trojan on your computer when downloading a file or media from P2P application. 
  • Compromise of privacy. Sharing files using P2P applications may provide unauthorized individuals access to personal information and sensitive data (similar to your financial and medical records) stored on the P2P application or on your computer.  
  • Prosecution. If you download pirated software or copyright material, even unknowingly, you may be subject to legal actions and heavy fines. 

Minimize the Risk

The best method to eliminate the risk is to avoid using P2P applications. However, if you are planning to use one, make sure to:

  • Install and run anti-virus software. Anti-virus software detects malware on your computer, software, and files. As malicious individuals work diligently to release new and sophisticated malicious codes, it is important to keep your anti-virus up to date with the latest definitions by regularly installing new updates. 
  • Know the P2P Filesharing software you are installing. When you load a P2P file-sharing application onto your computer, changes you made to the application's default setting may grant the application's users access to your personal folders on sub-folders. To protect your privacy, read carefully about the P2P file-sharing application and its features before loading it onto your computer, and only enable features you need to use.
  •  Install and enable personal computer firewall. A firewall can block some malicious traffic from reaching your computer. By installing and enabling a personal computer firewall you are adding a second layer of security in protecting your computer and data. 
  • Exit the program. The best method to close a program is by clicking exit. In some cases clicking "X" on the application doesn't close the application allowing it to run on your computer consuming your Internet bandwidth while granting access to your folders. You may also need to adjust the file-sharing program's controls to prevent it from opening automatically. 
  • Back up sensitive data. Back up all files and software you need access to in the event your computer crashes or when you lose access to these files in a clear readable format. Store the backup disk in a secure and safe location, e.g. locked file cabinet.
