Aplicarea modelelor NATO pentru constituirea infrastructurii informaționale în situații de criză

The effective functioning of the national security system during disasters, accidents and other crisis situations related to cyber security and cyber defence requires the realization of opportunities for inter-institutional interaction of all elements of the system. This paper presents certain opportunities as part of the methodology to apply NATO models to develop the system design of information infrastructure with capabilities to achieve the required levels of operational interoperability to respond to cyber threats to national security. For the architectural configuration, the NATO Technical Reference Model (NTRM) is applied and the NATO Common Operating Environment Component Model (NCOECM) is used for defining the information infrastructure components of the system design. By implementing the proposed methodology, a model of architectural configuration of an information infrastructure of a Security Operations Centre component has been developed – the Security Information Event Management (SIEM) Server. A specification of the technical and software configuration of the SIEM server is developed.
