MAKING CITIES INTEROPERABLE IN TURKEY

The population of cities is increasing rapidly day by day, and it is predicted that this increase will continue in the following years. Accordingly, population growth creates a significant pressure in many different domains of cities such as infrastructure, traffic, energy, and environment. Smart cities come forward as a useful option to struggle with the pressure on cities caused by overwhelming population growth and to make cities liveable and sustainable. Smart city approach creates gains in the fields of sustainable development, competitiveness and environmental sustainability with its ability to transform information into economic, social and environmental benefits. However, smart city services and applications are mostly designed as independent and unrelated units so this approach causes isolated and heterogeneous data and technology islands. As the result, data flow problem occurs between vertical applications and service suppliers, and this interoperability problem causes emergence of independent silos in smart cities. Such silos hinders data integration, prevent citizens and public administrations benefit fully from smart cities, and cause vendor lock-in. In order to use the full potential of smart city approach, it’s vital to secure interoperability systems and applications of smart cities. In this study, interoperability terms and their necessity for smart city ecosystem will be addressed. Afterwards, Smart City Interoperability Model’s (SCIM) contributions to semantic, technical and operational interoperability will be discussed.

Development of a Platform for Securing Interoperability between Components in a Carbon-Free Island Microgrid Energy Management System

The rigidity of information technology (IT) has been hindering the development of various businesses regarding energy management systems (EMSs) of power networks, although this area has become more diversified, resulting in changes of elements in the systems due to the introduction of renewable energy (RE) and the new energy industry. In order to effectively accommodate these changes, EMSs should be developed in a structure with a standard-based interface, which can secure interoperability between components in the EMS. In previous studies, the common information model (CIM) proposed by IEC TC57 has been utilized for developing EMSs of power networks, but there are gaps between the existing CIM and an information model for the EMSs of carbon-free island microgrids (MGs), which are a newly introduced form of power network covering multiple islands for reducing carbon emissions. This paper proposes a CIM-based software platform for a carbon-free island MG-EMS to efficiently operate the power network and secure interoperability between components in the MG-EMS. Concerning service restoration of the power network, use cases and business objects representing information exchanged between the components in the EMS are derived, and the existing CIM is extended based on the results of the gap analysis in order to provide necessary information on the MG-EMS. The validity of the proposed platform is verified by exchanging payloads between components in the MG-EMS based on the profile extracted from the extended CIM. Furthermore, the performance of the proposed platform regarding data size and speed of data exchange is presented. Based on the case study results, it is concluded that the proposed platform based on the extended CIM can exchange data between the components in the MG-EMS, achieving reasonable data size and speed of data exchange with the help of the interoperability between components in the carbon-free island MG-EMS.

Secure Interoperability in Cyber-Physical Systems

Transparency in control transactions under a secure network architecture is a key topic that must be discussed when aspects related to interconnection between heterogeneous cyber-physical systems (CPSs) arise. The interconnection of these systems can be addressed through an enforcement policy system responsible for managing access control according to the contextual conditions. However, this architecture is not always adequate to ensure a rapid interoperability in extreme crisis situations, and can require an interconnection strategy that permits the timely authorized access from anywhere at any time. To do this, a set of interconnection strategies through the Internet must be studied to explore the ability of control entities to connect to the remote CPSs and expedite their operations, taking into account the context conditions. This research constitutes the contribution of this chapter, where a set of control requirements and interoperability properties are identified to discern the most suitable interconnection strategies.

SYNTHESYS+ Molecular Collections in the Age of Genomics: Standards and processes

The aim of the Global Genome Biodiversity Network (GGBN, http://www.ggbn.org) is to foster collaboration among biodiversity biobanks on a global scale in order to further compliance with standards, best practices, and to secure interoperability and exchange of material in accordance with national and international legislation and conventions. Thus, key aspects of GGBN’s mission are to develop a network of trusted collections, establishing standards, and identifying best practices by reaching out to other communities. This is especially critical in the light of new international legislation such as the recent Nagoya Protocol on Access and Benefit Sharing (ABS). Biological repositories such as but not limited to natural history collections, botanic gardens, culture collections and zoos are facing a series of challenges triggered by the rapid acceleration in sequencing technology that has put added pressure on the use of samples, which just a few years ago were considered inaccessible for sequencing. ABS legislation applies to nearly all collection types, and with biodiversity biobanks increasing in number worldwide, there is an urgent need to streamline procedures and to ensure legislative compliance. Within Europe it is necessary to 1) reach common standards for biodiversity and environmental biobanks; 2) define best practices for the use of molecular collections; and 3) try to ease exchange of samples and related information, while staying compliant with legislation and conventions. Within the EU funded SYNTHESYS+ project (http://www.synthesys.info), GGBN is leading Network Activity 3 (NA3). An overview of planned activities and tasks will be given here with special emphasis on linkages within and beyond SYNTHESYS+.

Data Security In Cloud Computing: A Review

Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet. Cloud computing uses the internet and the central remote servers to support different data and applications. It is an internet based technology. It permits the users to approach their personal files at any computer with internet access. The cloud computing flexibility is a function of the allocation of resources on authority’s request. Cloud computing provides the act of uniting. Scientific computing in the 21st century has evolved from fixed to distributed work environment. The current trend of CloudComputing (CC) allows accessing business applications from anywhere just by connecting to the Internet. Evidence shows that, switching to CC organizations' annual expenditure and maintenance are being reduced to a greater extent. However, there are several challenges that come along with various benefits of cloud computing. Among these include securityaspects. Our aim is to identify security challenges for adapting cloud computing and their solutions from real world for the challenge that do not have any proper mitigation strategies identified. This non-existence of global standards and guidelines could be help academics to know the state of practice and formulatebetter methods/standards to provide secure interoperability. The identified cloud computing security challenges and solutions can be referred by practitioners to understand which areas of security need to be concentrated while adapting/migrating to a cloud computing environment.
