In fact, it has been proved that causal consistency is the strongest consistency model that can be enforced in an always-available system. Previous approaches to provide causal consistency, which successfully tackle the problem under full geo-replication, have unveiled the inherent tradeoff between the concurrency that the system allows and the size of the metadata needed to enforce causality. When the metadata is compressed, information about concurrency may be lost, creating false dependencies, i.e., the encoding may suggest a causal relation that does not exist in reality. False dependencies may cause artificial delays when processing requests, and decrease the quality of service experienced by the clients. Nevertheless, whether is possible to design a scalable solution that only uses an almost negligible amount of metadata and it is still capable of achieving high levels of concurrency under partial geo-replication, an increasingly relevant setting, remains as a challenging and interesting open research question. This position paper reports on the on-going development of Saturn, a metadata service for geo-replicated systems, that aims at mitigating the effects of false dependencies while keeping the metadata size small (even for challenging settings as partial geo-replication).","PeriodicalId":224203,"journal":{"name":"Proceedings of the Doctoral Symposium of the 16th International Middleware Conference","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122321393","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}

Smart meters are installed at homes, measure electricity consumption, and provide a two-way communication with the utility server. Modern cars consist of tens of Electronic Control Units (ECU) that control different components of the car such as speed, door locks, and breaks. Medical devices such as pacemakers and insulin pumps are implanted in the bodies of patients, and control their heart rate and insulin level. These devices are performing critical tasks and hence, their security is important. However, in recent years, researchers have found vulnerabilities in all these classes of devices, and have successfully demonstrated attacks against them. Given the critical nature of use cases of embedded systems, building Intrusion Detection System (IDS) for them is a necessity. However, embedded systems have constraints that make building IDS for them challenging. One of these constraints is memory. Memory capacity of embedded devices may be as small as several hundreds of kilobytes. This makes traditional solutions for building IDSes unusable. In my research, we analyze the security of embedded devices. Based on the results of my analysis, we develop techniques to automatically build IDSes for embedded devices, within their memory capacity, while optimizing the detection rate of the IDS with respect to the user's criteria. This research, makes developing IDSes for different classes of embedded systems, and with different memory capacities easier, and improves their security.","PeriodicalId":224203,"journal":{"name":"Proceedings of the Doctoral Symposium of the 16th International Middleware Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123978163","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}

Horizontal scalability is hindered by the ACID properties and the normalized data model these systems use. For this reason, a whole new range of database systems (NoSQL systems) has emerged. This paper focusses on eventual consistent storage systems, which have a certain inconsistency window after an update. Within this window different replicas contain a different version of a certain data item. While RDBMS systems provide strong transactional semantics, this is not the case for eventual consistent storage systems. The level of consistency is often configurable, but figuring out the optimal configuration is not a trivial task. Next to that, recent research has shown that the size of the inconsistency window can change over time, considering a fixed configuration. In this Phd research we envision a solution where all consistency-related parameters are managed by an SLA-driven autonomous system. Continuously monitoring the size of the inconsistency window allows dynamic reconfiguration and re-provisioning of the database cluster to keep the inconsistency window under a certain limit. As such, more guarantees can be provided to the application programmer.","PeriodicalId":224203,"journal":{"name":"Proceedings of the Doctoral Symposium of the 16th International Middleware Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125155212","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}
