Outline Definition of P2P P2P vs. Client/server Sharing Large Files Security and Risks Applications Discussion: current P2P issues Survey results

Peer to Peer Networks (P2P) “A method of file sharing over a network in which individual computers are linked via the Internet or a private network to share programs/files. Users download files directly from other users' computers, rather than from a central server.” -Harvard information technology Department

P2P structure  Nodes ( computers )communicating to each other through with out dedicated servers or hierarchy  Nodes work as both clients and servers to the other nodes in the network  Users decide what can and can’t be accessed

VS. P2P vs. Client/Server Networks

Using P2P to share /large files To share large files from one node to another would use too much bandwidth and take to long. To solve that BitTorrent is a method of distributing large amounts of data widely without the original distributor incurring the entire costs of hardware, hosting and bandwidth resources The more nodes in a network the quicker and more efficient the file will travel

Risks of P2P poisoning attacks polluting attacks freeloaders insertion of viruses to carried data malware in the peer-to-peer network software itself denial of service attacks filtering identity attacks spamming

How to Protect Yourself Don't Use P2P On a Corporate Network Beware The Client Software Don't Share Everything Scan Everything

How to protect your Business Attempt to control your desktops to prevent P2P software from being installed Limit the traffic at the firewall Educate your users!!! Ex: Japanese PolicemanJapanese Policeman

Applications Limewire - File Sharing Limewire BitTorrent – File Sharing BitTorrent Joost - P2P TV Joost Skype - P2P Phone Skype
