Moving Target Defense (MTD) intends to change the (presumable) information asymmetry between attacker and defender in favor of the defender by constantly changing a network's appearance as to invalidate previously acquired information. Many papers discussing MTD have been proposed and in recent years MTD techniques for a wide range of applications in enterprise networks, Cloud environments, IoT, automotive CAN buses and smart grids have been proposed. In these papers, MTD is often introduced as a \"game changer\" and explained with help of nice figurative analogies. Yet, how useful are these repeated changes really to deter the attacker? And even more importantly, could it not be that there are downsides to the constant changes that, ultimately, degrade security? In this position paper we argue that one needs to have a more critical and open minded view on MTD. There are MTD techniques that improve security. But we also provide several examples where they reduce security or where movement does not matter at all and is only introduced as to label a given technique as MTD.","PeriodicalId":155089,"journal":{"name":"Proceedings of the 17th ACM International Conference on Computing Frontiers","volume":"45 2-3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114132045","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}

Matching the patterns of known attack (filtering-based or rule-based) and finding the deviation from normal behavior (anomaly-based) are two typical approaches to prevent insiders from stealing sensitive information. On the one hand, filtering-based or rule-based solutions provide accurate identification of known attacks, and thus they are suitable for IP theft prevention, but they cannot handle the insiders with in-depth knowledge of the protective measures. On the other hand, anomaly-based solutions can find unknown attacks but typically have a high false-positive rate, which limits their applicability to practice. Nowadays, more and more researchers believe that the insider attack could be improved when combining known attack pattern matching with anomaly detection technologies. Therefore, in this paper, we introduce a Data-level Hybrid Framework, dubbed as Terminator, which enabling both detection and prevention. Terminator integrates a prevention module with an anomaly detection module and uses feedback to improve the module for detection or prevention. Different from previous anomaly-based methods that could only detect anomalous activities, Terminator could detect the stealing actions proactively and take real-time actions on these actions. The effectiveness of Terminator is demonstrated by its excellent performances on a collected dataset, involving detailed information in a real-world insider network and attack data simulated by impersonating the genuine users.","PeriodicalId":155089,"journal":{"name":"Proceedings of the 17th ACM International Conference on Computing Frontiers","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033956","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}

Most proposed solutions only track the explicit information flow where the taint is propagated through data dependencies. However, recent evasion attacks exploit implicit flows, that use control flow in the application, to manipulate the data thus making the malicious activity undetectable. We propose NIFT - a nested implicit flow tracking mechanism that extends explicit propagation to instructions affected by a control dependency. Our technique generates taint instructions at compile time which are executed by specialized hardware to propagate taint implicitly even in cases of deeply-nested branches. In addition, we propose a restricted taint propagation for data executed in conditional branches that affects only immediate instructions instead of all instructions inside the branch scope. Our technique efficiently locates implicit flows and resolves them with negligible performance overhead. Moreover, it mitigates the over-tainting problem.","PeriodicalId":155089,"journal":{"name":"Proceedings of the 17th ACM International Conference on Computing Frontiers","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132170660","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}

The Global Address Space Programming Interface (GASPI) communication API promises to handle this challenge by providing a highly flexible and efficient programming model in a partitioned global address space (PGAS). Suitable applications targeting supercomputers include the domain of mesh-based solvers for partial differential equations (PDEs) due to their high computational intensity. The implementation of such solvers is highly interdisciplinary, which therefore requires an abstraction of hardware-specific parallelization techniques from developing numerical algorithms. We present an open-source run-time system (RTS) that distributes and parallelizes device-agnostic kernels, which define algorithms on unstructured grids. We describe how the RTS abstracts common parts of iterative solvers and further explain how to parallelize and distribute these components. We further show the efficiency of our approach for several microbenchmarks and an implementation of the discontinuous Galerkin method (DGM). The results show that we can almost completely hide all synchronization overhead and that the RTS only imposes a small computational cost.","PeriodicalId":155089,"journal":{"name":"Proceedings of the 17th ACM International Conference on Computing Frontiers","volume":"132 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121474942","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}

Quantum computers can be conceived from basic photonic elements, such as Mach-Zehnder interferometers (MZI), but they still need control mechanisms and sensing elements from traditional VLSI technology. In this study, we present an ongoing study on a potential architecture for these basic photonic circuits. We realized two Photonic Integrated Circuit (PIC) test structures embedding metallic thermistors as phase shifters and silicon photodiodes as output detectors. We present a complete characterization of the phase shifter elements for an effective on-chip PIC interaction. To induce a consistent phase shift still retaining coherence of light, we act on the phase-shifters by means of a closed-loop control. By controlling through Pulse-Width Modulation the phase shifters, we drive the path of photons accurately in the PIC, demonstrating the effectiveness of the proposed configuration for the management of a photonic chip.","PeriodicalId":155089,"journal":{"name":"Proceedings of the 17th ACM International Conference on Computing Frontiers","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123809104","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}
