We consider an approach for construction of analytical models of cyber attacks and negative impacts based on the stochastic networks conversion. This approach has high accuracy and stability of the decisions and has worked well for modeling multi-stage stochastic processes of different nature. The result of the modeling is the distribution function of the time and the average time for implementation of cyber attacks. We also build analytical models for implementation of countermeasures, and integrate them with the analytical models of cyber. As the result the integrated analytical model of the behavior of computer networks under conditions of cyber actions is formed. They allow one to estimate and to choose the most effective countermeasures. These estimates are then used to find the indicators of cyber resilience. The results of experimental evaluation of cyber resilience of computer networks and discussion are given.","PeriodicalId":340686,"journal":{"name":"2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131232085","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 considered SS-FON supports spectral super-channel transmissions, in which flexible signal regeneration is realized with transceivers operating in back-to-back (B2B) configurations. We propose an Adaptive Survivable Routing with Back-to-Back Regeneration (ASRBR) algorithm to realize dynamic routing requests protected with the DPP method. The ASRBR algorithm is aware of limited spectrum and transceivers resources and makes use of the flexibility of the B2B regeneration. With the use of the ASRBR algorithm, we examine potential performance gains in terms of bandwidth blocking probability (BBP) in two regeneration scenarios: a reference one in which the use of regenerators is minimized and the modulation conversion is not allowed and intentional regeneration with possible modulation conversion. We analyze the efficiency of ASRBR for a set of various network scenarios using two representative topologies. Evaluation results show that the proposed method outperforms other reference algorithms. Moreover, the flexible B2B regeneration provides better utilization of both spectrum and transceiver resources, resulting in lower BBP than the minimal regeneration scenario. Finally, we study potential performance gains from applying a squeezed protection approach.","PeriodicalId":340686,"journal":{"name":"2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132029541","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}

As CDNs utilize the underlying optical core network infrastructure, they inherit its vulnerability to targeted link cut attacks which can cause severe service degradation. One of the fundamental problems in CDN configuration is deciding on the placement of content replicas across the underlying network of data centers, which should obtain balance among multiple, often conflicting performance criteria. This paper investigates the implications of minimizing the average distance between the users and the content replicas on the CDN robustness to targeted link cuts.To this end, we compute Pareto-optimal replica placement solutions with minimal user-to-replica distance and maximal robustness to link cut attacks of the highest damaging potential. k-best replica placement solutions in terms of the user-to-replica distance are calculated by formulating the problem as an Integer Linear Programming (ILP) exact method. For each replica placement solution, the worst case link cut attack scenario is identified by defining the Critical Link Set Detection (CLSD) problem. CLSD returns the link set whose cutting disconnects the maximal number of nodes from the content. We develop an ILP model for the CLSD and evaluate the robustness of the resulting CDN attack scenario in terms of mean content accessibility. The approach is evaluated through extensive simulations on real-world reference topologies, indicating that it is possible to improve the robustness to link cuts at the expense of small user-to-replica distance penalties. Moreover, the improvement of robustness is more significant for topologies with smaller average node degree and when cuts involve a larger number of links.","PeriodicalId":340686,"journal":{"name":"2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123512248","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}

SBS models extend classical network reliability models (where the components subject to failure are nodes or links of a graph) and are able to represent more complex interactions between the states of the individual components and the operation of the system under study.The reliability evaluation of stochastic binary systems belongs to the class of ${mathcal{N}}{mathcal{P}}$-Hard computational problems. Furthermore, the number of states is exponential with respect to the size of the system (measured in the number of components). As a consequence, the representation of an SBS becomes a key element in order to develop exact and/or approximation methods for reliability evaluation.We introduce the concept of separable stochastic binary systems, whose structure can be efficiently represented. Reliability bounds for arbitrary SBS are provided inspired by a measure of a distance to a separable system, duality and Chernoff inequality. Opportunities for future work arising from this representation are also discussed.","PeriodicalId":340686,"journal":{"name":"2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128940684","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}

To the best of our knowledge, this is the first comprehensive framework which utilizes tools from all these fields in a joint design of disaster resilient connections. In particular, we introduce a new probabilistic regional failure model, which does not only take into account the distance from the epicenter of the failure, but includes the (improved) availability values of the network components into the model, too. Based on the failure list generated as the result of the availability-aware disaster failure model, dedicated protection approaches are used to route the connection requests. We demonstrate the concept and benefits of FRADIR through experimental results in two real-like network topologies. Our proof-of-concept implementation shows that with the interplay between protection routing, failure modeling and network update procedure the network performance in terms of blocking probability and average resource consumption can be significantly improved, which makes FRADIR a possible competitor to provide disaster resiliency in critical infrastructures.","PeriodicalId":340686,"journal":{"name":"2018 10th International Workshop on Resilient Networks Design and Modeling (RNDM)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131836886","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}
