Managerial simulators enable us to experiment easily with all possible variants of alternative decisions. This facilitates the process of assessing the effective policies and strategies formed by the managers. The creation of simulators based on the principles of system dynamics in the background is the main point of interest of this diploma thesis. This paper is focused on building a simulator which would simulate policies of communication from the position of Information manager, depending on the variable settings of its parameters. The structure of the model and the parametrization of the simulator comes from practical experiences from the company called NETservis s.r.o., which specializes on the development of internet applications for large international companies. The simulator is therefore intended for the simulation of policies in this particular company, however can also serve as a referential model and be used by other companies.

The aim of the diploma thesis it is a promotion of the system works and mainly the advantages of system thinking in the praxis of the information manager, system thinking limits setting as unique and necessary way of thinking, learning and tremendous potential prezentation of system thinking for the information manager job. There is emphesized the need of connecting the paradigma of system thinking knowledges with psychology knowledges potential. The system thinking presents collection of mental practics and system steps leading towards systems functions understanding, model creation and variants selection .It is really necessary the information manager would be able to do a quality process analysis where he would be able to map all transformation spots with data objects and would be able to propose the information strategy the information manager has to have many years of experiences and manage the system thinking skills.

The Intrusion Detection Systems (IDS) have appeared as a solution for detention and correction of intrusion of pro-active way. Thus, some models of SDIs have appeared to diminish the probability of compromising of on computational systems connected in net, identifying, reporting and answering to these incidents. In face to that diversity of solutions, they lack proposals of standardization of the information used for these Systems, as well as of mechanisms of interoperability and exchange of information between the solutions in use. This dissertation, proposes a model, an architecture and an implementation of a SDI´s Information Manager, using the technologies of Multi- Agents Systems and Web Services. The objective of the Information Manager is to keep the information that are necessary to the development of the inherent functions of a SDI, in a safe and updated way. We also propose a standard of format for storage of these data to insert requirements in the environment, as: Unified Storage, Transparent Access, Uniform Generation of Data and Friendly Interaction. / A Segurança digital tem se tornado fator inegociável para instituições de diversos domínios. Os Sistemas de Detecção de Intrusão (SDIs) têm surgido como uma solução para detecção e correção de intrusão de forma próativa. Assim, vários modelos de SDIs têm surgido para, identificando, reportando e respondendo a estes incidentes, diminuir a probabilidade de comprometimento dos sistemas computacionais ligados em rede. Diante desta diversidade de soluções, faltam propostas de padronização das informações utilizadas por estes Sistemas, bem como de mecanismos de interoperabilidade e troca de informações entre as soluções em uso. Esta dissertação, propõem um modelo, uma arquitetura e uma implementação de um Gerenciador de Informações para SDIs, usando as tecnologias de Sistemas Multiagentes e Web Services. O objetivo do Gerenciador de Informações é manter de forma segura e atualizada as informações que são necessárias ao desenvolvimento das funções inerentes a um SDI. É proposto também, um padrão de formato para armazenamento desses dados, de forma a inserir no ambiente requisitos como: Armazenamento Unificado, Acesso Transparente, Geração de Dados Uniforme e Facilidade de Interoperabilidade.

The main goal of this work is the application of system thinking in computer networks design and use of the systems thinking as a unique way of thinking and the presentation of the big potential which the systems thinking has in complex problem solving. Advanced network technologies are also described with their benefits for any organization. This thesis brings a whole new sight at the computer networks as a complex system and describes procedure of making a computer project in detail which can be used as a general reference model in the field of computer technologies. Solution include strong accent on how the basic knowledge of computer networking is important for information manager profession.
