Malware distribution using drive-by download attacks has become the most prominent threat for organizations and individuals. Compromised web services and web applications hosted on the cloud act as the delivery medium for the exploits. The exploits included often target the vulnerabilities within the plugins of the web browsers. Implementing security controls to counter the exploits within the browsers...
The scalability and dynamic configuration of service clouds can be susceptible to Distributed Denial of Service (DDoS) attacks. The attack on web services causes a performance decrease in the cloud applications or can shut them down. Additionally, due to the high distribution of the service cloud components, finding the original attacking service becomes a far more complex task. This paper advocates...
This paper presents a framework to ensure the correctness of service-oriented architectures based on runtime verification techniques. Traditionally, the reliability of safety critical systems is ensured by testing the complete system including all subsystems. When those systems are designed as service-oriented architectures, and independently developed subsystems are composed to new systems at runtime,...
In all European countries, initiatives are implemented towards promoting the use of Information and Communication Technologies (ICT) in schools. However, the current level of school ICT uptake remains low, due to the interrelation of a wide range of factors, including teachers' ICT competences and strategic school Leadership planning. In this context, there is a need for systems that will facilitate...
It is critical of self-adaptive software system to monitor all kinds of information in real-time and obtain relevant data of the system to make the system can adjust automatically when necessary. In order to cope with the current market needs and rapidly changing environment, and combine the Web services with self-adaptive software systems perfectly, we proposed a monitoring and prediction model for...
The currently used communications layer in the electric power grid is heavily outdated and thus not able to cope with emerging Smart Grid application requirements. Notably, new measurement devices and advanced control applications are being deployed with the aim to greatly improve the stability and efficiency of the grid. A communication infrastructure together with a middleware that delivers updates...
The cases of infections, hospitalizations and deaths from dengue in the world represent a scenario that involves a series of public policy. Among the hosts of the disease tropical countries, Brazil stands out with high levels of potentially alarming cases, mainly due to its environmental and social conditions favorable to the proliferation of the mosquito Aedes Aegypti. Given scenario, this paper...
Water quality management is inevitably complex, since it involves a number of technical, socio-economic, environmental and political factors with dynamic and interactive features. In planning water quality management, there are uncertainties in many system components and they may affect the overall behavior. It is thus desired that such complexities and uncertainties are effectively addressed, for...
Due to advances in wireless network technology, new applications are designed in medical and health care domain. Medical personnel efficiency has increased by using these new tools and applications. Patient of young and elderly people as well as smart houses equipped with sensors and information technologies are subject to discussion. Patients wear sensors to monitor vital signs reported in real-time...
The Repository of services (web-applications with a unified interface) is proposed for patient care (care services), for planning and carrying out of treatment (treatment services) and to ensure the functioning the entire system (management services). Treatment of diabetes becomes personalized and customized because it is possible to build and adjust their treatment plan and workflow by selecting...
Internet application workloads typically vary over time, periods of low demand alternate with spikes which, if not properly handled, can saturate the allocated infrastructure and violate Service Level Agreements. In this work, we leverage the usage patterns associated with the different customers of an Internet application to make tailored workload predictions. These workload predictions are then...
Monitoring and management of large scale applications is already a complex task because of syntactic and unstructured nature of execution data. Traditional application monitoring and management solutions focused on employing analysis techniques on unstructured and syntactic log information become limited as unstructured information cannot be well utilized to find out related events information or...
Monitoring managing large scale applications has always been a crucial and complex task on which enormous efforts and research have been carried out towards making the process efficient, effective and automated. However, the process is still complex, lacks efficiency and effectiveness because execution workflow representation and logging (outcome from real-time execution) is rendered in a syntactic...
Considering to the deficiencies of the traditional static model synergies for the dynamic changes of enterprise requirements, this paper proposes a new reliable service recommendation model to support service resource optimization, service choosing, and optimal service recommendations. In this paper, a set of indices and the evaluation methods are discussed for measuring the qualities of services...
Effective management of the supply chain is becoming increasingly important for modern enterprises. A supply chain consists of several sub-processes, internal and external to the enterprise, which are nevertheless rarely executed as planned because deviations due to disruptive events are very common. In this paper we present an event-based framework which is designed to sense events generated by external...
We contribute performance functions to model the quality of service (QoS) of web services in horizontal composites. Performance functions are thereby used to formalize service level agreements (SLAs) to enable automated verification. Inter-Component rating is a model for gathering additional QoS information from web services that rate the output of their predecessor web services in composites. Furthermore,...
For service-based applications which are composed of multiple independent third-parties, continuous monitoring is required to assure that runtime behavior of the systems complies with specified properties. However, most existing work only detects the violation while not consider how to enforce the properties so that the constraint can not be violated at runtime. To address this limitation, this paper...
Service software deployed in E-commerce and finance fields needs working under 7*24 houses mode. If any failure occurs, service reconfiguration should be immediately executed to find appropriate services from candidates in order to guarantee the availability of core business. Thus, service software cries for an effective approach to constantly adjust its form for responding to varying user requirements...
Performing functionality testing in serviceoriented architectures is not a trivial task. The difficulty is especially the large number of components that may be present in a SOA such as brokers, providers, service registries, clients, monitoring tools, data storage tools, etc. Thus, in order to facilitate the process of conducting functional testing and capacity planning in service-oriented systems,...
Research on sensor network has been focused at overcoming these deficiencies through more energy efficient routing, localization algorithms and system design. This paper tried to discuss some application related challenges, such as data integration, data storage, metadata generation, data fast query. We use analytical data management concept to create a virtual layer, which maps the real sensor network...
