Защита информации в организациях : методика исследования угроз, уязвимостей и рисков
The monograph is devoted to the development of research methodology of threats, vulnerabilities and risks in information security in organizations. Substantiated mathematical apparatus of research: axiomatization of Boolean , which as most adequately describes the processes of mental activity in the construction of expert system model of information security in the organization and eliminates various types of heuristics that are typical of artificial intelligence languages . Methodology contains descriptive ( verbal ) and math ( formalized ) components . The technique developed formalized description of threats, vulnerabilities and risks of information protection systems and synthesis of relations between them allows you to fully analyze and document requirements related to information security in the organization, avoiding the cost of excessive security measures possible in the subjective assessment of the risks to assist in planning and implementation of protection at all stages of the life cycle of information systems, ensure that work in the shortest possible time, provide a justification for the choice of countermeasures to evaluate the effectiveness of countermeasures to compare their various options. The monograph provides examples of using methods for cal factor calculations , ensuring correct the validity of decisions of experts in information security in organizations. For managers and specialists units for the protection of information.
The main focus of this paper is the rights of children in post-communist Russia. With this in view I give a brief overview of child's rights under the communist regime and after the Soviet Union breakdown. Further, I will examine in more detail the current situation with children's rihgts and, particularly, the child's right to protection. Tp make it more illustrative, after giving a legal framework, I will address the most acute and pressing problems in the field.
As a result of war with France, British tariffs were raised to protect domestic beverage production. This helped promote the beer industry during the infancy of industrial brewing in the 18th century. But protection also led to monopoly controls in order to promote easier taxation and greater regulatory oversight. This chapter shows that this severely distorted the consumption of alcohol and the production of domestic substitutes like beer in Britain, but that it also enabled the state to grow by providing it with a mechanism for dramatically raising taxes to fund the century's many wars. Reversing protection in the 19th century was complicated and fraught with interference from domestic lobbies that hampered the British move to free trade.
This paper outlines the phenomenon of «fear» as a component of Thomas Hobbes (1588-1679) philosophy. The author makes an attempt to submit the concept of the «rational» fear as the basis of political philosophy of the English philosopher, with a special attention given to some «problematic» place of this concept.
On May 18-19, 2012, at the presidential retreat in Camp David in Maryland, U.S. president Barack Obama hosted the 38th annual G8 summit. The leaders discussed global economic growth, development, and peace and security. After less than 24 hours of face-to-face time among the leaders, they issued communiqué of only five pages. However, Camp David was a significant success. The leaders came together to effectively address the most pressing issues of the day while setting the direction for the summits that were to follow, including the summit of the North Atlantic Treaty Organization in Chicago, the G20 in Los Cabos, Mexico, and the Rio+20 Summit in Rio de Janeiro, Brazil. That success was propelled by several causes. The first is the set of strong global shocks were particularly relevant to a number of items on the agenda. This included the newest installment of the euro-crisis, spikes in oil and food prices, and the escalating violence in Syria. The second is the failure of the other major international institutions to address these challenges. The third is the club’s dedication to the promotion of democracy and its significance on issues such as the democratic transition in the Middle East and North Africa. The fourth is the high relative capabilities of G8 members, fuelled by the strength of the U.S. dollar, the Japanese yen and the British pound. The fifth is the domestic political control, capital, continuity, competence and commitment of the leaders in attendance. Camp David saw several G8 leaders returning for their sixth or seventh summit and leaders with a secure majority mandate and control of their legislative houses at home. Finally, the constricted participation at the remote and secluded Camp David Summit, a unique and original advantage of the G8 summit style, allowed for more spontaneous conversation and interpersonal bonds. Together, these interconnected causes brought the G8 back, as a broader, bigger, bolder centre of effective global governance.
The post-Cold War Arctic has seen a transformation from military tension and a focus on national security to a concern for environmental and human security. As a result of this, the globalized Arctic has a high level of peace and stability, maintained by international cooperation between the Arctic states, northern indigenous peoples, sub-national governments and local actors. There has also been a shift from environmental protection to economic activities and, consequently, states easily trump other interests. Now, in the Arctic, these challenges require fresh thinking on a local and global scale. Regional wars, the 'war on terror', and economic crises have posed new threats to Northern security order.
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.
Generalized error-locating codes are discussed. An algorithm for calculation of the upper bound of the probability of erroneous decoding for known code parameters and the input error probability is given. Based on this algorithm, an algorithm for selection of the code parameters for a specified design and input and output error probabilities is constructed. The lower bound of the probability of erroneous decoding is given. Examples of the dependence of the probability of erroneous decoding on the input error probability are given and the behavior of the obtained curves is explained.
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
