ITU-T recommendations on peer-to-peer (P2P) network security

Peer-to-peer (P2P) networks use diverse connectivity between participants in networks. P2P networks are useful for many purposes. Sharing content files containing audio, video, data or anything in digital format is very common, and real-time data, such as telephony traffic, is also passed using P2P technology. Because the P2P communication model differs from that of conventional server and client system, further security threats emerge, which are not applicable to server and client architecture. The Telecommunication Standardization Sector (ITU-T) developed network security Recommendations for P2P telecommunications on behalf of the International Telecommunication Union (ITU). This paper provides general survey of the Recommendations.
