It proposes a security-by-design approach intended to link the encoded policy to the security policy modeling. However, this technique does not tie in the specificity and heterogeneity of web applications and hence the proposed model-to-code transformation doesn't fit the needs of web architects. Consequently, web applications are mainly hand-coded, or correspond to legacy code developed before the implementation of security mechanisms. Security concerns are mixed with the application code and hence it is difficult to understand the policy in order to maintain, correct, or evolve it. This work deals with access control mechanisms following the RBAC pattern. Our work proposes a toolset dedicated to modeling and deployment of an acces control engine for a web application assuming that the functional part of the application is developed following a classical process. Our technique tries to reconcile modeling, validation and implementation of role-based security policies, and favours model driven security in the context of web applications. The toolset allows developers to graphically model an MVC web application by making links to its requirements and then generates a security filter from the web application's model. This technique guaranties that the deployed access control policy is conformant to its specification and associated validation activities.","PeriodicalId":405980,"journal":{"name":"Proceedings of the Fifth European Conference on the Engineering of Computer-Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123617086","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}

Connected vehicles have sensors and Electronic Control Units (ECUs) that perform in-vehicle communications, and they communicate with the other entities using cellular, vehicular, and wireless networks. These communications may be compromised through different attacks including Man-In-The-Middle (MITM) and Man-At-The-End (MATE) attacks. Existing security solutions are not suitable for this complex integration between different technologies. In this paper, we provide a taxonomy of connected vehicle attacks that can be classified into four main categories. We identify the relations between these attacks and connected vehicle attributes and security requirements. We also present a trust model that contains various countermeasures to secure connected vehicles against different attacks. This trust model consists of four components: integrity, access control, availability, and privacy. The proposed trust model will ensure the achievement of the security requirements against common MITM and MATE attacks.","PeriodicalId":405980,"journal":{"name":"Proceedings of the Fifth European Conference on the Engineering of Computer-Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133081083","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}

In model-based testing, an implementation under test is tested for compliance with a model that describes the required behaviour of the implementation. Uppaal Tron is a popular tool for online model-based conformance testing of real-time systems; it uses the Uppaal verification engine to generate and convert on-the-fly timed symbolic traces into concrete test sequences. Among the advantages of online testing is the reduction of the symbolic state space needed for computing traces, better addressing non-determinism, as well as the possibility to execute longer-lasting test runs. However, analysing and debugging long test runs can be tedious and time-consuming especially when analysing root causes of failed tests. In game theory, backward-induction is a process to reason backwards in time, from the end of a problem or situation, in order to determine a sequence of optimal actions. In this paper, we propose an approach to reconstruct symbolic traces from test sequences generated by Uppaal Tron using backward-induction. The resulting symbolic traces can be imported in the Uppaal tool and visualised in the Uppaal simulator. The evaluation of the implementation of the approach shows that it has the potential to satisfy the needs of industrial level testing.","PeriodicalId":405980,"journal":{"name":"Proceedings of the Fifth European Conference on the Engineering of Computer-Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117251671","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}

We have dealt with popular technologies and languages for data storage and data management, such as XML, SQL, XPath, REST, BPMN, etc. In this paper we sum up our contributions and present a complex example of evolution process of an information system. We model complex situations that, starting from a single point, influence the whole system. Our solution, however, brings benefits not only for a typical system with the well-known architecture \"presentation layer -- business layer -- database layer\", but also for the micro-service architecture that becomes more and more popular these days. In this paradigm every service is specialized, it manages a specific logical part of the system, and it communicates with other services mainly via HTTP or (web) sockets. This architecture brings many advantages especially to system scalability, performance, and resource management. On the other hand, separation of the system to micro-services brings drawbacks, such as more demanding change management and version compatibility. For example, a change of the message structure in one part of the system can influence all related services, integration tests are more complex and must detect more edge cases that in case of monolithic systems, etc. A mechanism that can analyze the changes, propagate them, and/or at least inform the developer about possible inconsistency can reduce time needed for updates and troubleshooting.","PeriodicalId":405980,"journal":{"name":"Proceedings of the Fifth European Conference on the Engineering of Computer-Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116969188","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, approaches enabling use case driven modularization require to modularize code manually. In this paper, we propose an approach to employing issues and commits for in-code sentence based use case identification and remodularization. The approach aims at providing use case based perspective on the existing code. The sentences of use case steps are compared to sentences of issue descriptions, while the sentences generated from the source code of issue commits are compared to sentences generated from the corresponding methods in source code in order to quantify the similarity between use case steps and methods in source code using different similarity calculation algorithms. The resulting level of similarity is used to remodularize source code according to use cases. We conducted a study on the OpenCart open source e-shop employing 16 use cases. The approach achieved the recall of 3.37% and precision of 75%. The success of the approach strongly depends on issues and commits assigned to them. The results would be better especially for the code that natively employs use case driven modularization.","PeriodicalId":405980,"journal":{"name":"Proceedings of the Fifth European Conference on the Engineering of Computer-Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122827486","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}
