Architecture of the system of intelligent information security services in critical infrastructures
The paper describes the overall architecture of the system of intelligent information security services (SIISS) for usage in critical infrastructures, as well as its constituent components. In the overall architecture of SIISS the event level, the data layer and applied level are determined. Structural and functional models of the SIISS overall architecture are outlined to highlight the main functional mechanisms for selected levels. As key components of SIISS, which provide a more detailed description of their architectural design, we consider the event correlation management module, the prognostic security analyzer, the component of attack and security system behavior modelling, the decision support and reaction component, the visualization module, and the repository.
