Peer to Peer File Sharing (P2P)

What is P2P File Sharing?

Peer to Peer (P2P) file sharing is a method of sharing files between two systems directly.  Typically these computers list files available for sharing using a local file listing service that is incorporated into the software.  The most common use for P2P file sharing is related to the unauthorized and illegal sharing of copyright protected content such as music, licensed (by cracked) programs, and video content.

Is All P2P File Sharing Illegal?
Absolutely not!  There are plenty of legitimate uses for P2P file sharing.  Often open source programs are shared among the community using P2P. 

What is the Risk?
Far too often, the default configuration of P2P software shares far more than the user is expecting.  Although there are legitimate uses for P2P software, they are usually indicators of illicit activities.  If you find anything with "Torrent" or "Limewire" in the title, that is a possible indicator.  Far too often teen children will install this software to steal free music only to have their parents discover later the issue exists when they receive official notice from the RIAA.  Fines for digital media theft can exceed $150,000 USD.

Protective Measures:

1.  Unless you have a absolute requirement for P2P software, never install it.  If its installed now, discover why, who is using it, and remove it as soon as possible.

2.  If P2P software is required, check the set up of the software to ensure the discovery is locked down to only the a single folder, that we are aware of what is displayed.
