Abstract: “Too often, the unified security programs, based on comprehensive analy ses of unified information from across the IT infrastructure, are costly, complex, difficult to implement and inefficient. As a result, most organizations lack accurate threat detection and informed risk - management capabilities. Therefore, the response to new information security threats can be a “security intelligence” approach. It is based on art ificial intelligence and the use of its methods to protect from cybercrimes. The aim of this study is to present and compare different methods of artificial intel ligence for fighting the crime in cyberspace, or rather their application in systems for detecting and preventing intrusions”
