Peer-to-Peer overlay network provide various services for the feature of storing, discovering and locating resources efficiently. P2P platform raise more security-related challenges while providing more services. WhenP2P security mainly focusing on the security problems on overlay, this paper first shows the how to the authors classify threat and how to they provide the security mechanisms to that network. This paper also discuss about the various security services. Peer-To-Peer (P2P) is a kind of distributed technology characterized by its self-organization ability. P2P network is an overlay network built upon the traditional underlay IP network. Its main function is to store, discover and locate resources efficiently.
