Building the computing infrastructure is only the first step towards the successful execution of the cyber exercises. The design, validation, and deployment of scenarios are costly and error-prone activities that may require specialized personnel for weeks or even months. Furthermore, a misconfiguration in the resulting scenario can spoil the entire cyber exercise. In this paper, we propose a framework for automating the (i) design, (ii) model validation, (iii) generation and (iv) testing of cyber scenarios. We introduce a Scenario Definition Language (SDL) based on the OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA). SDL allows for the high level, declarative specification of the components and their interplay. We show that SDL specifications can be encoded into Datalog and that this allows for the automatic checking of the resulting model against a set of validation goals. If the check fails, then a design modification process is triggered. Otherwise, the validated scenario can be automatically deployed on the cyber range. The validation proof is then automatically converted into test cases whose successful execution gives evidence that also the deployed scenario meets the validation goals.","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127794074","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, FEC operation latency overhead surprisingly becomes higher than the sum of all the other switch operation overheads, e.g., routing computation and switch allocation. FEC operation latency overhead significantly degrades the performance of parallel applications in HPC systems. Instead, in this study, we exploit the low-latency network design using a Hamming code that does not provide rigid error-free communication. Since it is consistent with existing frame format based on standard Reed-Solomon RS(544,514) with DC(64b/66b) direct linecode and TC(256b/257b) transcode, respectively, the influences upon the other network layer design are limited. Interestingly, a large number of parallel applications can accept the BER in such a Hamming code. Since lowering such a BER improves switch operation latency, the proposed network using the Hamming code improves the execution time of NAS Parallel Benchmarks by 56% on average when compared to the counterpart RS-FEC networks.","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"304 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113995776","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 paper is focused on malware detection based on using features extracted from the network traffic and system logs. We evaluated the performance of four supervised machine learning algorithms (i.e., J48, Random Forest, Naive Bayes, and PART) for malware detection and identified the best learner. Furthermore, we used feature selection based on information gain to identify the smallest number of features needed for classification. In addition, we experimented with training sets of different sizes. The main findings include: (1) Adding network flows-based features improved significantly the performance of malware detection. (2) J48 and PART were the best performing learners, with the highest F-score and G-score values. (3) Using J48, the top five features ranked by information gain attained the same performance as when using all 88 features. In the case of PART, the top fourteen features ranked by information gain led to the same performance as when all 88 features were used. None of the system logs-based features were included in these two models. (4) The classification performance when training on 75% of the data was comparable to training on 90% of the data. As little as 25% of the data can be used for training at an expense of somewhat higher, but not very significant performance degradation (i.e., less than 7% for F-score and 6% for G-score compared to when 90% of the data were used for training).","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"82 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114059506","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, this multi-cloud strategy faces several security challenges including enlarged attack surfaces, malicious insider threats, security complexities due to integration of disparate components and API interoperability issues. Novel security approaches are imperative to tackle these security issues. Therefore, this paper proposes CS-BAuditor, a novel cloud security system that continuously audits CSB resources, to detect malicious activities and unauthorized changes e.g. bucket policy misconfigurations, and remediates these anomalies. The cloud state is maintained via a continuous snapshotting mechanism thereby ensuring fault tolerance. We adopt the principles of chaos engineering by integrating BrokerMonkey, a component that continuously injects failure into our reference CSB system, CloudRAID. Hence, CSBAuditor is continuously tested for efficiency i.e. its ability to detect the changes injected by BrokerMonkey. CSBAuditor employs security metrics for risk analysis by computing severity scores for detected vulnerabilities using the Common Configuration Scoring System, thereby overcoming the limitation of insufficient security metrics in existing cloud auditing schemes. CSBAuditor has been tested using various strategies including chaos engineering failure injection strategies. Our experimental evaluation validates the efficiency of our approach against the aforementioned security issues with a detection and recovery rate of over 96 %.","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123726986","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 addition to long range communications, one of the most solid arguments in favour of the LoRaWantechnology is its ability to operate at orthogonal spreading factors (SFs). This enables simultaneous transmissions at different data rates on the same frequency channel. But Recently, it has been shown that transmissions at different SFs are not perfectly orthogonal which generates cross-SF interferences (i.e. interferences between different spreading factors' transmissions). Therefore, we propose here an analytical model of a single cell LoRaWAN under unsaturated traffic, duty cycle and multi-channel deployment conditions. The model considers both perfect and imperfect SF orthogonality scenarios. The network performance are then derived in terms of achievable throughput at the gateway as a function of the offered load, the number of received packets per device and the percentage of successful transmissions. All the Results show that if spreading factors are assumed to be orthogonal, the capture effect improves the network performance in comparison with the theoretical pure Aloha access scheme. Whereas, the consideration of imperfect SF orthogonality revises the LoRaWAN performance downward.","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115474000","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, the ever-changing workload in a data center makes it difficult for VM consolidation to prevent service level agreement (SLA) violations and optimize power consumption. Detection of overutilized and underutilized physical machines (PMs) plays a significant role in effective VM consolidation, immediately improving resource utilization, SLA violations, and power consumption. This paper presents a new proposal for the dynamic adjustment of threshold values that aims to minimize the number of migrations in varying workload environments. The proposed approach, named the ‘dynamic threshold-based fuzzy approach’ (DTFA), is a fuzzy threshold-based approach used for adjusting the threshold values of PMs in a cloud environment. The proposed approach allows the number of migrations caused by overloading to be reduced and SLAs to be met. Three sets of experiments with different workloads were conducted to validate the proposed approach. The results demonstrate that DTFA outperforms existing solutions by an average of 22.52%, 45.63% and 56.68% in power consumption, VM migration count, and SLA violations, respectively.","PeriodicalId":268662,"journal":{"name":"2018 IEEE 17th International Symposium on Network Computing and Applications (NCA)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124750411","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}
