P2p clients

P2P Category DescriptionThis SonicWALL IPS signature category consists of a group of signatures that can detect and prevent network traffic associated with Peer to Peer (P2P) filesharing networks. These networks allow users to download and share music, movies, pictures, software, etc and are often used on corporate networks to take advantage of a broadband connection. Besides posing legal liabilities and decreasing productivity, P2P networks pose a variety of threats to network performance and security. Most obviously, P2P file sharing causes can clog a network by substantially increasing traffic. Not only do P2P applications allow users to download mutli-megabyte or gigabyte files, increasing inbound traffic; they also allow computers inside a network to function as servers, causing large increases in outbound traffic as well. This activity can choke bandwidth, slowing down legitimate communcation, and even resulting in denial of service.More seriously, P2P clients can compromise network security by effectively boring holes into firewalls. P2P networks send information over a port that is not usually used for network traffic, for example port 1214. Because most firewalls block these ports, P2P clients will often ask the user to disable security restrictions on these ports. Many clients also implement tunelling techniques where the P2P traffic is disguised as normal web traffic which many firewalls assume is harmless. In both of these instances, this unprotected port is an attractive target for attackers who can use it to establish a backdoor connection and take control of computers within the networks. P2P clients thus give users not

Mass at Amherst Mema Roussopoulos, Harvard University 2 What is P2P? P2P is a communications model in which each party has the same capabilities and either party can initiate a communication session. Whatis.com P2P is a class of applications that takes advantage of resources – storage, cycles, content, human presence – available at the edges of the internet. Clay Shirky, openp2p.com A type of network in which each workstation has equivalent capabilities and responsibilities. Webopedia.com A P2P computer network refers to any network that does not have fixed clients and servers, but a number of peer nodes that function as both clients and servers to other nodes on the network.
