| Resumo: | The growing markets of Cloud services and IoT platforms have dramatically raised system flexibility and deployment options. However, increasing complexity and dependency on third-party providers make it difficult to assess the security and privacy levels that distributed systems can offer to their users. In the last years, machine-readable Service Level Agreements (SLAs) have been studied as an optimal method for copying with security and privacy policies. Still, the computation of the SLAs of applications distributed in diverse infrastructures remains a challenging task. This paper presents a methodology to compose security SLAs (SecSLAs) and privacy SLAs (PLAs) of Cloud-based IoT applications on top of standard controls. The composition considers individual components’ SLAs and the control delegation relationships between the components with respect to different types of controls (common, system-specific or hybrid controls). Furthermore, we propose a technique to calculate the Service Level Objectives (SLO) of the controls declared in the composite SLA based on the SLOs granted by individual components. Finally, the paper presents the validation of the methodology carried out to create the SecSLAs and PLAs of a real multiCloud-based IoT application in the eHealth domain. |
