Segurança e mobilidade em redes IEEE 802.11

: modelo de suporte à decisão na escolha de arquitecturas e tecnologias de redes sem fios

Abstract

The use of wireless networks based on IEEE 802.11 standards are today a wide used solution [1] for data communication in diverse environments, ensuring access of all kinds of devices to software platforms, applications and Internet platforms. The installation on public areas and large institutions involves the creation of infrastructure for access, the implementation of security models and the correct dimensioning for the service level desired [2], in order to reach the quality and reliability required for the users. The escalating use of mobile platforms (tablets, laptops and smartphones), inside and outside the corporate environments [3], represent new challenges and security concerns, which companies need to consider before making available their business applications with acceptable levels of risk. In these environments, the security requirements, performance and quality of service are especially relevant when business applications are involved, mainly because confidentiality, integrity and privacy of information are critical aspects for companies in a competitive world. This thesis presents a detailed study on the specificities of this type of networks at the physical level, access control, architecture, security models and also discusses the latest developments with a perspective of their use in business environments. In addition to an overview of problems and solutions, we propose a methodology for decision support in the selection of architectures, technologies and security services, based on a security and a risk analysis process that guide the architectural design model, the implementation and operation processes to a wireless network
