Well\r\nknown P2P networks include for example BitTorrent and Spotify. P2P networks\r\nare an alternative to a traditional client/server model, which is used very com-\r\nmonly in data transferring within the Internet. Both P2P and client/server sys-\r\ntems are used most commonly to transfer information via an information net-\r\nwork. Information security is an extremely important subject, since the continu-\r\nously growing amount of electrical data processing and especially transferring\r\nconfidential data within in information networks is increasing the risk for data\r\ncorruption. In the wrong hands, important data can be used to create significant\r\ndamage to private persons and organizations. This thesis was conducted as a lit-\r\nerature review, and it explores the P2P networks in general and presents chal-\r\nlenges to the information security related to them. The objective of the thesis is to\r\nfirst create a clear image of what P2P networks are, how they work and how they\r\ndiffer from client/server models. Then, the information is discussed in general\r\nand within the context of P2P networks and the challenges to information secu-\r\nrity in P2P networks are highlighted. As a result of this research it is discovered,\r\nthat the greatest challenges for information security in P2P networks are network\r\nviruses, routing attacks, access attacks, malicious attacks and Sybil attacks.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Toni Miettinen (tomimiet) on 2016-01-26 10:22:16.314818.
