Internet of Things (IoT) is slowly taking over the world where its predicted that by 2025, it will grow to 1-3 trillion connected machines/devices. With large scale deployments, maintaining these devices is a seeming burden on the operations. Also, with huge deployments of IoT devices, most concerns center around privacy and security. To reduce the efforts of on-field maintenance and to perform such...
Fraud prevention in the banking sphere is a very important type of activity which can cover a whole range of fraud schemes — both from employees and customers. The article studies the existing technologies for realization of the system of security control over functioning of POS networks in real time and analyzes them in detail. Besides, the concept of the system of monitoring and analysis of threats...
In-network processing pushes computational capabilities closer to the edge of the network, enabling new kinds of location-aware, real-time applications, while preserving bandwidth in the core network. This is done by offloading computations to more powerful or energy-efficient surrogates that are opportunistically available at the network edge. In mobile and heterogeneous usage contexts, the question...
The need to apply complex algorithms on large volumes of data is boosting the development of technological solutions able to satisfy big data analytics needs in Cloud and HPC environments. In this context Ophidia represents a big data analytics framework for eScience offering a cross-domain solution for managing scientific, multi-dimensional data. It also exploits an in-memory-based distributed data...
The ability to remotely discover and configure devices in an automation network without the need for prior knowledge of the network topology or the identities of hosts and servers is a key requirement for industrial networks and cyber-physical systems. The Dynamic Host Configuration Protocol (DHCP) as a UDP-based standardized network protocol became very successful in computer networking and also...
Linux Server Operating system is widely used in electric power SCADA systems in China. In order to study the performance difference between different distribution Linux Server operating systems so that we can select an appropriate distribution to use, the paper compares four secure Linux server operating system's performance using lmbench benchmarking methodology. The experiments showed that lmbench...
Cyber-physical systems are an emergent paradigm to design complex, adaptive and smart systems, combining computational applications with physical hardware devices. Multi-agent systems play an important role in such systems to provide flexibility, robustness and adaptation, but their alignment will require the integration of agents with physical devices. This process is usually complex and time consuming...
The energy consumption of Cloud computing continues to be an area of significant concern as data center growth continues to increase. This paper reports on an energy efficient interoperable Cloud architecture realized as a Cloud toolbox that focuses on reducing the energy consumption of Cloud applications holistically across all deployments models. The architecture supports energy efficiency at service...
When orchestrating highly distributed and data-intensive Web service workflows the geographical placement of the orchestration engine can greatly affect the overall performance of a workflow. Orchestration engines are typically run from within an organisations' network, and may have to transfer data across long geographical distances, which in turn increases execution time and degrades the overall...
Field Device Integration (FDI) is recently defined automation standard that provides a common platform to integrate and configure field devices that works on different protocols from different manufactures. The FDI standard incorporates the advantages of existing device integration technologies such as Field Device Tool (FDT) and Electronic Device Description Language (EDDL). This paper presents a...
Vulnerability management constitutes a crucial activity within autonomic networks and systems. Distributed vulnerabilities must be assessed over a consolidated view of the network in order to detect vulnerable states that may simultaneously involve two or more devices. In this work, we present a novel approach for describing and assessing distributed vulnerabilities in such self-governed environments...
Autonomic computing has become an important paradigm for dealing with large scale network management. However, changes operated by administrators and self-governed entities may generate vulnerable configurations increasing the exposure to security attacks. In this paper, we propose a novel approach for supporting collaborative treatments in order to remediate known security vulnerabilities in autonomic...
The server virtualization architecture, encompassing the sharing of data storage subsystems among the virtual servers or operating systems on a single host server using I/O channel sharing capabilities in fibre channel fabrics, was pioneered by IBM through their system z9 mainframe and its predecessors. The implementations of I/O channel sharing capabilities were based on the fibre connectivity channel...
Until very recently, energy efficiency has received little attention in many wired communications environments. For example, in most current Ethernet standards the transmitter and receiver operate at full power even when no data is being sent. However, new upcoming energy-aware standards, such as Energy Efficient Ethernet (EEE), are addressing this issue by introducing a low power mode for idle link...
