Cloud-based applications are able to adapt themselves dynamically to the workload behavior due to such mechanisms. The efficient instantiation of Virtual Machines (VMs) is one requirement for the elastic behavior of cloud-based applications. This study characterizes the performance of VM instantiation in a private cloud platform, considering distinct factors such as VM type, VM image size, and VM caching. We employed a full factorial design of experiments (DoE) to compute the effect and relevance of the factors as well as their interactions. Our experimental results show that the cache factor has an impact of 45.07 % on the total instantiation time, whereas the machine image (MI) has 26.45 % and the VM type only 1.05 %. The results of these experiments are also used as input parameters in a Markov chain model for sensitivity analysis. The model evaluation showed that for 6 GB and 8 GB MI, the probability of finding the MI on cache must be at least 40 % and 60 % respectively, to achieve an average instantiation time of 300 seconds. For MI with size 2 GB, such time is not exceeded even with the cache disabled. This analysis allows checking the impact of every parameter on the system response time and pointing out effective ways for improvement of performance. Such conclusions may be used as decision support for systems which often instantiate new VMs, including those using elasticity features, such as auto scaling.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131732377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the number of mobile applications grows exponentially, a crucial issue is how users will monitor and manage their media 'flows' to optimal levels. This means having 'requisite' levels of information and communication, while avoiding states of hyper-connectivity. Our research is focused on developing mobile applications that analyze users' multiple media flows. A dashboard interface then offers feedback to the user, who can adapt and modify her or his behavior for improved productivity and personal well-being.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126189199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, Web Services have raised new challenges on information security, this technology is susceptible to XML Injection attacks, which would allow an attacker to collect and manipulate information to insert malicious code in either server-side or client-side, being one of the most employed attack against web applications according to the OWASP Top 10. Different studies have shown that the current testing techniques -- penetration testing and fuzzy scanning -- generate several false positives and negatives. However, the fault injection technique improve the robustness of web applications, through the greater flexibility to modify the test cases and to find software bugs. This work describes a fault injection technique for the evaluation of Web Services robustness with WS-Security (Username Token) and the development of a set of rules for vulnerability analysis, resulting on the improvement of the vulnerability detector accuracy. Our results show that 82% of web Services tested were vulnerable to XML Injection attacks.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128764411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A main concern of context-aware services is a substantial consumption of resources while preserving a minimal level of accuracy. There is a tradeoff between efficiency and accuracy on context acquisition. Hence, we propose a cloud-based Context Acquisition Platform to provide a high-level of efficiency over a certain level of accuracy required by a context-aware service. The platform mediates between context-aware services and sensors. With the platform, the context acquisition is only done by it and the context values are shared by multiple context-aware services, which can substantially reduce the cost to acquire context so that efficiency can be largely increased.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129830082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing approaches suffer the following two drawbacks: 1) poor accuracy of filling values to services, 2) not designed for service composition. In this position paper, we first present the recent approaches improving the process of filling values to services. We then present our recent achievements and results of using our proposed approaches to help users fill values to services.

They inevitably carry confidential information such as passwords, encryption keys, mission-critical company data, or location information in combat areas. In order to meet sophisticated security requirements, recent technology focuses on policy-oriented approaches that allow for the definition and enforcement of rigorous and precise rules for protecting confidential information. State-of-the-art development of security policies is a critical process, because of the involved quality assurance measures, it is quite heavy-weighted and tends to antagonize the distinguished virtues of mobile devices for lightweight, spontaneous communication and cooperation. This paper presents an approach to support secure, mobile device based cooperation in temporary, sporadically and spontaneously fashioned cliques within open communication infrastructures. The approach is based upon light-weight security domains protected by security policies that are dynamically and automatically composed during group formation. Due to the volatile nature of such groups simplicity, adaptability, efficiency and compatibility with today's security policy implementation techniques have been a major design goal.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125967395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on this scenario, we propose a framework, called Automated Mobile Testing as a Service (AM-TaaS), which offers automated test for mobile applications based on AQuA's test criteria. We performed an experiment emulating nine Android mobile devices with different characteristics in order to test the criterion \"OTA Install\" (automated installation of mobile applications in a device).

Experimental results show 100% of the emulated devices could be tested using automated test cases designed in the framework for this test criterion.","PeriodicalId":106002,"journal":{"name":"2015 IEEE World Congress on Services","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122345496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
