Peer-to-Peer (P2P) is a file sharing method that connects computers so users can share files with each other. Files are shared directly from computer to computer without using a server. Napster and Limewire are examples of P2P sites. A virus on one computer can quickly spread to other computers on a P2P. Also, hackers can use a P2P to gain access to computers and then hack secure folders that may contain personal or company secrets. Copyrighted materials may be posted, which if used could subject the employee and company to legal prosecution. Thus, businesses should not allow their employees to connect to P2P networks.
