ANALYSIS OF SECURITY PROBLEMS OF PEER-TO-PEER NETWORKS

Abstract

The basic concepts of peer-to-peer networks are analyzed. The current areas of their use are indicated, namely file-sharing services, teleconferencing systems, gaming and trade services, etc. The types of structural organization are considered, and their advantages and disadvantages are determined. According to the degree of centralization, pure, hybrid and federal architectures are distinguished. The classification of peer-to-peer peer networks by connection method and function is also given. Analysis of the prevalence of peer-to-peer networks in the modern world has proved the demand and relevance of the use of decentralized network technology, especially in the field of finance. Possible types of attacks on peer-to-peer networks are analyzed. Both general and specific attacks are highlighted. Specific attacks are oriented on user, application or network. Methods and mechanisms of protection for each of the studied types of attacks are given. The results of the analysis are systematized, namely for each attack the impact on the data, the degree of danger and the level of protection is determined. It also indicates the direction of violation of information security of each attack, namely the integrity, accessibility, confidentiality. It turned out to be no less interesting for malefactors, as evidenced by the significant number of hacks. The research of attacks on P2P networks showed a wide range of both general and specialized. At the same time, attacks are differentiated according to the degree of danger and the aspect of security breach. The most dangerous were attacks that could violate the confidentiality and integrity of data. These include the following attacks: distributed denial of service, index poisoning, sibyl attack, eclipse attack, botnets, masquerade. The research is the basis for further study of the shortcomings of the protection of peer-to-peer networks and the development of new secure mechanisms for data exchange in decentralized structures.
