Методика количественной оценки риска в информационной безопасности облачной инфраструктуры организации
Almost all of the technologies that are now part of the cloud paradigm existed before, but so far the market has not been proposals that bring together emerging technologies in a single commercially attractive solution. However, in the last decade, there were public cloud services, through which these technologies, on the one hand, available to the developer, and on the other - it is clear to the business community. But many of the features that make cloud computing attractive, may be in conflict with traditional models of information security.
Due to the fact that cloud computing bring with them new challenges in the field of information security, it is imperative for organizations to control the process of information risk management in the cloud. In this article on the basis of Common Vulnerability Scoring System, allowing to determine the qualitative indicator of exposure to vulnerabilities of information systems, taking into account environmental factors, we propose a method of risk assessment for different types of cloud deployment environments.
Information Risk Management, determine the applicability of cloud services for the organization is impossible without understanding the context in which the organization operates and the consequences of the possible types of threats that it may face as a result of their activities. This paper proposes a risk assessment approach used in the selection of the most appropriate configuration options cloud computing environment from the point of view of safety requirements. Application of risk assessment for different types of deployment of cloud environments will reveal the ratio counter possible attacks and to correlate the amount of damage to the total cost of ownership of the entire IT infrastructure of the organization.
Widespread acceptance and adoption of cloud computing calls for adaptation and development of existing risk assessment models of information systems. The approach suggested in this article can be used for risk assessment of information systems functioning on the basis of cloud computing technology, and assess the effectiveness of security measures.
The proceedings of the 11th International Conference on Service-Oriented Computing (ICSOC 2013), held in Berlin, Germany, December 2–5, 2013, contain high-quality research papers that represent the latest results, ideas, and positions in the field of service-oriented computing. Since the first meeting more than ten years ago, ICSOC has grown to become the premier international forum for academics, industry researchers, and practitioners to share, report, and discuss their ground-breaking work. ICSOC 2013 continued along this tradition, in particular focusing on emerging trends at the intersection between service-oriented, cloud computing, and big data.

These technologies have emerged as the hottest networking trends of the past a few years. The conference proceeding represent the papers where the broad scope of SDN&NFV topics are discussed.
Modeling threats and vulnerabilities of information security is widely used as a foreign practices and recommendations of national standards . The key disadvantage of the methods is the lack of a formalized description of conceptual solutions for the design of information systems. In this regard, the article proposes to consider a special variant of the description of the conceptual solution in the form of formalized '' models'' . This is an important step in establishing links between business requirements and capabilities of information technology. The article proposes to improve existing solutions architecture, consisting of three key components: the modeling component and architectural risk analysis module .
The use of cloud computing to ensure interaction between the state and citizens allows to speed up information interaction, to realize state services, to reduce the costs of providing such interaction, but at the same time this interaction raises important questions about the reliability of the cloud provider and security of interaction. Providers of the cloud can be both public authorities and private organizations. In the event that the cloud provider is a government agency, it can be assumed that all the requirements for security will be met. However, if the cloud provider is a private person, then we cannot be sure of security, if these requirements for security are not mandatory. It should be noted that Russian legislation does not require the mandatory application of information security standards. In this regard, the security of stored information in the clouds and its legislative support, the responsibility of providers providing cloud access services are very significant for the use of this technology in Russia.
Cloud-based technologies proliferated in the past few years, while the manufacturing industry moved towards digitization and network. Therefore, cloud-based technologies have been adopted in the development of new generation manufacturing systems which orchestrate different activities, including product design, process and task planning, production, customer service, etc. These new cloud-ingrained technologies have the potential to change the collaboration of product development partners, the processing and sharing of information as well as utilization rates of critical equipment. Cloud-based technologies affect many aspects of manufacturing activities, and they therefore have the power to enable new or change existing business models of the manufacturing industry. Based on the literature review, this paper analyzes the latest requirements, challenges, and trends of the manufacturing industry. It structures the findings in the coherent manner and further hypothesizes how cloud computing may address identified requirements and challenges as well as realize or support new concepts in manufacturing.
Need to improve and increase the efficiency of the cardinal principles of information security management cloud environment leads to the area of multidimensional properties of " systematic ." Application of technology and methods of structural synthesis of formal information security management systems (ISMS ) in the cloud , connecting different structure hierarchies requirements would more effectively take advantage of already developed in each of the local provisions technologies and means of automation properties and systemic manifestations . Provides an excellent opportunity to empirically model the inherent objectives tree type property of their systematic structure. Particular attention is paid to this article trees building for the purposes of identifying the security requirements of cloud computing environment and forming the basis of a formalized synthesis platforms security of information technology systems , operating on the basis of cloud computing technology , in accordance with defined criteria and taking into account the systemic factor in the development of the system.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
Existing approaches suggest that IT strategy should be a reflection of business strategy. However, actually organisations do not often follow business strategy even if it is formally declared. In these conditions, IT strategy can be viewed not as a plan, but as an organisational shared view on the role of information systems. This approach generally reflects only a top-down perspective of IT strategy. So, it can be supplemented by a strategic behaviour pattern (i.e., more or less standard response to a changes that is formed as result of previous experience) to implement bottom-up approach. Two components that can help to establish effective reaction regarding new initiatives in IT are proposed here: model of IT-related decision making, and efficiency measurement metric to estimate maturity of business processes and appropriate IT. Usage of proposed tools is demonstrated in practical cases.
