This diploma thesis is concerned with simulating information security management within a university environment. It is divided into three parts. The theoretical part focuses on describing the assets which could be part of a faculty network, attacks that could target it, security processes which could protect it and users that are active within it. The analytical part then applies these segments on a real faculty network. Based on this analysis, a set of specific assets, attacks, security processes and other tasks is created in order to simulate a simplified version of the analyzed network using a sophisticated cybernetic polygon. The security of the network is then assessed after several iterations of the simulations. Its parameters are adjusted in the effort to increase its security and the module is tested on an academic employee in order to assess its effectiveness. The conclusion evaluates the possibilities of increasing the security of the simulated network as well as the usability of the cybernetic polygon in practice.
