Mathematical Modelling in Cyber Security Management

Cyber security is the most critical aspect of the technological-based lives. The increasing interest in it leads to adopt computer architectures, with a close relationship between hardware, sofware and security. The paper presents the case of applying a Multi- Attribute Decision Making model and Onicescu solving method, in order to select a hardware - software infrastructure used to acquire and process the information concerning computer security incidents. Each pair hardware - software infrastructure is evaluated using a set of characteristics. The pair with the greatest evaluation value is the optimal solution.
