No. of bitstreams: 1 PABLO GULIAS RUFINO DE FREITAS.pdf: 2140333 bytes, checksum: 1e937a0df855e15ff38bbf36da286844 (MD5) Previous issue date: 2017-05-02 / Pontif?cia Universidade Cat?lica de Campinas ? PUC Campinas / Traditionally, Information Security (IS) and Quality of Service (QoS), which means the capacity of a service to satisfy the needs of a user, have been considered separately, with different purposes and needs. However, the service levels that are advertised and expected for both are strongly linked. In this sense, despite the improvement in the performance of communication and of the confidentiality, integrity and the availability of data trafficked having greater premise, there still is no standardization for the joint and efficient use of IS and QoS. There are also no defined metrics or indicators that allow for this grouped measurement. This study proposed and tested a model for the management of communication networks, based on the best practices of the library for Information Technology Service Management (ITSM), Information Technology Infrastructure Library (ITIL), having the novelty of using the information security risk management process, from the 27005 (Risk Management) standard, in conjunction with a list of requirements checks of QoS and controls from the 27002 (Code of Practice) standard. This study looks to find the equilibrium between IS, performance and productivity. The results obtained showed the effectiveness of this proposal decreasing by approximately 16%, the number of incidents directly linked to IS and QoS, detected and solved in a proactive manner. / Tradicionalmente, Seguran?a da Informa??o (SI) e Qualidade de Servi?o (Quality of Service (QoS)), que significa a capacidade de um servi?o para satisfazer as necessidades do usu?rio, t?m sido consideradas, separadamente, com diferentes prop?sitos e necessidades. No entanto, os n?veis de servi?os anunciados e esperados por ambos est?o fortemente ligados. Nesse sentido, apesar da melhoria no desempenho da comunica??o e da confidencialidade, integridade e disponibilidade dos dados transportados serem premissas maiores, ainda n?o h? uma padroniza??o para um uso conjunto e eficiente entre SI e QoS. Tamb?m n?o h? uma defini??o de m?tricas ou indicadores que possibilitem essa medi??o agrupada. No presente trabalho, prop?e-se e testa-se um modelo de gerenciamento de redes de telecomunica??es, baseado nas melhores pr?ticas da biblioteca de Gerenciamento de Servi?os de Tecnologia da Informa??o (GSTI), Information Technology Infrastructure Library (ITIL), tendo como novidade a utiliza??o do processo de gest?o de riscos de seguran?a da informa??o, da norma 27005 (Gest?o de riscos), em conjun??o com uma lista de verifica??es de requisitos de QoS e controles da norma 27002 (C?digo de pr?ticas). Este trabalho busca o equil?brio entre SI, desempenho e produtividade. Os resultados obtidos mostraram a efetividade da proposta com uma diminui??o aproximada de 16%, da quantidade de incidentes diretamente ligados ? SI e QoS, detectados e solucionados de forma proativa.
