Concrete proposals on how to eliminate conditions conducive to the commission of cyber fraud are made and ways of effectively countering fraud committed through computer and telecommunications devices and computer networks are proposed. The prerequisites for the birth and development of the World Wide Web are studied, and the dynamics of the growth in the number of users in the world, Europe, Asia, USA, Ukraine are analyzed. Conclusions about the credibility of statistics on the number of active users of computer and telecommunication networks are drawn, the way they are counted, factors affecting data corruption, along with consideration for their most effective use. The reasons for passivity, lack of effectiveness of the security structures of the private sector in the fight against criminal encroachments using computer networks and technologies are identified.

A lot of companies have a problem with the selection of the type of computer network, because each of them has different characteristics and specifications. A businessman often does not know what he can expect from them and which type of network will allow him to fully exploit the potential of its business. The main objective of the work is to build a decision support system in this area. Intermediate target is to specify the characteristics or criteria which will be guided by a businessman in this selection. A comparative analysis of the type of access to the network using a case study was made in the work. The paper also developed the concept of a decision support system on the issue in question. As a result, six benchmarking criteria were specified and analyzed: security, data integrity, price, mobility, performance and configuration. As a result of the analysis, the final ranking was presented. Having used AHP method it showed which type of access to the network according to the given criteria provided by a businessman was the most suitable for him.
