Abstract-Applying model-driven development methodologies provide inherent benefits such as increased productivity, greater reuse, and better maintainability, to ñame a few. Efforts on achieving model-driven development of web services already exist. However, there is currently no complete solution that addresses non-functional aspects of these services as well. This paper presents an ongoing work which seeks to intégrate these non-functional aspects in the development of web services, with a clear emphasis on security.

Abstract-Service-Oriented Architectures (SOA), and Web Services (WS), the technology generally used to implement them, achieve the integration of heterogeneous technologies, providing interoperability, and yielding the reutilization of preexistent systems. Model-driven development methodologies provide inherent benefits such as increased productivity, greater reuse, and better maintainability, to ñame a few. Efforts on achieving model-driven development of SOAs already exist, but there is currently no standard solution that addresses nonfunctional aspects of these services as well. This paper presents an approach to intégrate these non-functional aspects in the development of web services, with an emphasis on security.

Abstract. As a common reference for many in-development standards and execution frameworks, special attention is being paid to ServiceOriented Architectures. SOAs modeling, however, is an área in which a consensus has not being achieved. Currently, standardization organizations are defining proposals to offer a solution to this problem. Nevertheless, until very recently, non-functional aspects of services have not been considered for standardization processes. In particular, there exists a lack of a design solution that permits an independent development of the functional and non-functional concerns of SOAs, allowing that each concern be addressed in a convenient manner in early stages of the development, in a way that could guarantee the quality of this type of systems. This paper, leveraging on previous work, presents an approach to intégrate security-related non-functional aspects (such as confidentiality, integrity, and access control) in the development of services.

En los sistemas distribuidos modernos, como la Internet o Web de las Cosas, la seguridad juega un papel preponderante. Debe prestarse especial atención a la consideración de estos aspectos en las primeras etapas de desarrollo. En este contexto, el desarrollo guiado por modelos de requisitos no funcionales (NF) presenta especial interés, ya que aborda dichas características NF en la etapa de diseño, cuando todavía se pueden realizar análisis, y aún hay margen para modificaciones antes de queéstas sean muy costosas. El uso de estas metodologías guiadas por modelos ofrece beneficios tales como el aumento de la productividad, una mayor reutilización de los elementos de diseño, o una mejor mantenibilidad del sistema. Este artículo presenta una estrategia de desarrollo que permite integrar aspectos NF de seguridad (confidencialidad, integridad, y control de acceso) en los sistemas de software empotrado.
