    Implementation and Performance Analysis of Contex-Aware Role-Based Access Controls for Cloud-Based Iot Platform
    (Izmir Institute of Technology, 2019) Döşemeci, Mete Merthan; Ayav, Tolga
    IoT has received substantial attention in both industry and the scholarly world in the recent years. The main idea is to interconnect the physical world with the digital world. Sensors read physical world and present processible data. This data needs to be secured. Currently, most of the cloud based IoT platforms use some sort of Role-Based Access Control (RBAC) , which is one of the approaches to control access to the devices, hence the data. In some cases RBAC is insufficient for fulfilling constantly changing requirements of IoT. ABAC (Attribute Based Access Control) can be flexible enough for fulfilling. However ABAC requires higher level of maintenance. We wanted to implement a access control method that uses both RBAC’s and ABAC’s advantages. We called it OBAC(Operation Based Access Control). Authorization is being implemented in a plug and play manner. We implemented that way because; It is designed for cloud platforms and we wanted to switch between access control methods easily. The results of the experiment shows that proposed access control(OBAC) had minimum latency and management steps across other access control methods.

    Domain-Specific Modeling Based Feature-Oriented Automatic Test Generation Methodology for Software Product Lines
    (Izmir Institute of Technology, 2019) Şensülün, Sercan; Tuğlular, Tuğkan
    Cloud platforms are transforming to software product lines (SPLs) and testing of the customer-selected products are becoming increasingly important with this transformation. Acceptance Test (AT) is a testing variety to check acceptability of the software based on user requirements. While user requirements or customer’s selection are changing during the development cycle, cost of ATs generation is also increasing. In this study, a feature-oriented testing approach is proposed with a novel extension to Gherkin called SPL-AT Gherkin and a novel automatic test method generation technique that uses Test Next Generation (TestNG) framework. Applicability of the proposed approach is demonstrated with a case study that has different user interface (UI) components such as Page, Button, Text View and Edit Text in mobile application platform. Moreover, results for case study is presented. The proposed approach is open for improvement throughout any application that has UI components such as Web, Mobile with any testing framework.
