Established safety assurance approaches and standards have been designed with manually controlled stand-alone systems in mind and are thus not fit to ensure safety of this next generation of systems. We argue that, given frequent dynamic changes and unknown contexts, systems need to be enabled to dynamically assess and manage their risks. In doing so, systems become resilient from a safety perspective, i.e. they are able to maintain a state of acceptable risk even when facing changes. This work presents a Dynamic Risk Assessment architecture that implements the concepts of context-awareness, confidence-disclosure and fail-operational. In particular, we demonstrate the utilization of these concepts for the calculation of automotive collision risk metrics, which are at the heart of our architecture.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128935665","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}

This is highly relevant for critical software systems, where monitoring is often mandated by international standards and guidelines. In this paper, we analyze the effectiveness of a metrics-logs contextual anomaly detection technique in a middleware for Air Traffic Control systems. Our study addresses the challenges of applying such techniques to a new case study with a dense volume of logs, and finer monitoring sampling rate. Guided by our experimental results, we propose and evaluate several actionable improvements, which include a change detection algorithm and the use of time windows on contextual anomaly detection.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126819626","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}

It can tolerate crash faults and malicious misbehavior, but usually comes with high resource costs, not only by requiring multiple active replicas, but also by providing the replicas with enough resources for the expected peak load. This paper presents a vertical resource-scaling solution for SMR systems in virtualized environments, which can dynamically adapt the number of available cores to current load. In similar approaches, benefits of CPU core scaling are usually small due to the inherent sequential execution of SMR systems in order to achieve determinism. In our approach, we utilize sophisticated deterministic multithreading to avoid this bottleneck and experimentally demonstrate that core scaling then allows SMR systems to effectively tailor resources to service load, dramatically reducing service provider costs.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121588991","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}

Online Failure Prediction (OFP) is a technique that attempts to avoid or mitigate such failures by predicting their occurrence based on the analysis of past data and the current state of a system. Given recent technological developments, Machine Learning (ML) algorithms have shown their ability to adapt and extract knowledge in a variety of complex problems, and thus have been used for OFP. Still, they are highly dependent on the problem at hand, and their performance can be influenced by different factors. The problem with most works using ML for OFP is that they focus only on a small set of prediction algorithms and techniques, although there is no comprehensive study to support their choice. In this paper, we present an exploratory analysis of various ML algorithms and techniques on a dataset containing failure data. The results show that, for the same data, different algorithms and techniques directly influence the prediction performance and thus should be carefully selected.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132246631","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}

Given technical and budget constraints, the defender focuses on deploying the set of security countermeasures that offer the best level of system protection. However, optimizing the configuration and deployment of defense countermeasures for efficient attack detection and mitigation remains a challenging task. In this paper, we leverage the information present in an attack graph, representing the evolution of the state of the attacker in the system, to tackle the problem of finding the optimal security policy that offers the maximum level of system protection. Our solution can be used to assist asset owners to prioritize the deployment of security countermeasures and respond to intrusions efficiently. We validate our approach on an Advanced Metering Infrastructure (AMI) case study.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123635498","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 fact, even when data is anonymized there is a risk of re-identification through privacy attacks. This paper presents a re-identification risk-based anonymization framework for big data analytics platforms. This framework is based on anonymization policies and allows applying anonymization techniques and models in two stages: during the ETL process and before exporting the statistical results of data analytics. This second stage evaluates the data re-identification risk and increases the anonymity level if it is necessary to reduce this risk. Although generic, the implementation of the framework reported in this work was integrated into Ophidia as a case study. Privacy attacks were performed to check the effectiveness of the re-identification process. Results are promising, showing a low probability of re-identification in two different scenarios.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114820533","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}

OpenNCP is a major initiative for achieving interoperability of eHealth data among European Member States. It is an Open Source implementation of a broker-based solution that enables the exchange of clinical data among countries having different languages and regulations. It provides some level of protection - using common security technologies (e.g., TLS) - but it has not been designed with the specific goal of achieving high levels of security, and therefore it is vulnerable to more subtle attacks, such as those by privileged users and/or software. In this paper we discuss how the new extension of COTS processors - namely Software Guard eXtension (SGX) - can be exploited to implement effective mechanisms against this specific category of attacks, which is particularly challenging. We present a general approach to harden systems, and discuss in detail how we implemented it in the context of OpenNCP. Also importantly, we evaluate the performance degradation induced by SGX.","PeriodicalId":129399,"journal":{"name":"2018 14th European Dependable Computing Conference (EDCC)","volume":"417 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131527704","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}
