A methodological approach to the implementation of information protection measures against threats of unauthorized access to the technological process parameters values and their changes, implemented through a distributed control system and leading to an emergency at the oil refining facility, is proposed. An example of approbation of the methodological approach in the context of the distributed control system of the technological process of vacuum distillation is given. The results of assessing the possibility of implementing threats to the system with and without applied protection measures are presented.

Purpose: the need to assess the effectiveness of the security systems for significant objects of critical information infrastructure determines the need to develop simple and adequate mathematical models of computer attacks. The use of mathematical modeling methods in the design of security system of significant object allows without significant cost and impact on the functioning of the object to justify the requirements to the system as a whole or its individual parts. The purpose of the present paper is to develop a model of the process of multistage targeted computer attack that exploits the Zerologon vulnerability, based on the representation of the attack by a Markov random process with discrete states and continuous time. Methods: methods of Markov process theory, probability theory, computational mathematics and graph theory are used in the model to formalize the attack. Novelty: application of methods of computational mathematics for functional analysis of the results of Kolmogorov’s system of equations allows to solve the problem of maximizing the time of stable operation of critical information infrastructure during computer attacks against it, using the known methods of analysis of continuous functions. Result: formulated a general statement of the problem of modeling the process of a multistage targeted computer attack using a system of Kolmogorov equations, describing the probabilities of being in conflict states of the security system with the intruder. By the Adams method implemented in Mathcad environment, numerical solutions depending on time were obtained. We introduce a security system performance index as a ratio of probability of triggering the security system and blocking intruder’s actions during the attack to the probability of successful completion of the attack. We give an example of research of computer attack realization in a typical information infrastructure, including a corporate network with domain architecture and an automated control system of some technological process. 1 For the considered example defined the optimal values of time parameters of security system. When implementing protective measures with reasonable probabilistic-time characteristics proved an increase in time of stable operation of critical information infrastructure from 11 to 189 hours.

The relevance are substantiated and the calculation relations for computing the components of the integral performance indicator – private performance indicators – based on the technical characteristics of the network information security tool of an automated information and telecommunications system are determined. Present a variant of application of the proposed methodological approach on the example of multifunctional firewalls.

With food insecurity an incessant mounting concern, and the present food crisis wrought by current geo-political instability and Russia's invasion of Ukraine; the export of food from South America to Europe is increasingly a strategic axis for the development of international business. Within this context, sustainability and environmental considerations are another fundamental criterion in accessing and competing in international markets. Presently, myriad different standards exist in the context of international business, at both regulatory and voluntary levels. This paper focus on voluntary sustainability standards, which while not required by law, might increasingly be requested, or actively sought by manufacturers, retailers or consumers. The question is how might exporters decide and navigate between multiple voluntary sustainability standards when they want to open a new export market. We propose a method to facilitate selection of the most appropriate standard for a specific product targeting a specific export market, based on information provided by the International Trade Centre through its Standard Map tool. We use as an illustrative example oats exported by Chilean producers, which have export potential in different European Union countries. Our method identifies 10 sustainability standards from a total of 321, which are adjusted for oats products for human consumption from Chile., peer-reviewed

Hintergrund: Aus den Daten der EXPORT-Studie konnten wir ein multivariates Modell aufstellen, welches die Berechnung einer individuellen Erfolgschance der Ocriplasmintherapie bei vitreomakulärer Traktion (VMT) aus den Faktoren Alter und VMT-Durchmesser erlaubt.

Objective To estimate the proportion of patients with very severe osteoporosis (those covered by the reimbursement criteria of the Italian National Health Service) experiencing new vertebral and non-vertebral fragility fractures in the first 24 months of a new anti-osteoporosis treatment. Methods Prospective observational study in men and post-menopausal women (aged > 21 years) initiating anti-osteoporosis treatment for very severe osteoporosis. Eligibility was based on teriparatide (TPD) reimbursement criteria in Italy: Incident of vertebral or hip fracture during anti-resorptive treatment (minimum 1 year), or at least three prevalent severe vertebral fractures, or two prevalent severe vertebral fractures and a historical proximal hip fracture. Incidence of new clinical vertebral and non-vertebral fractures was documented by original x-rays and/or radiological reports, and a post-hoc analysis compared data from the TPD monotherapy population versus the total treated group. Results Overall, 767 patients (mean age 72.8 years, 90.7% women) were enrolled in the study, of whom 628, 538, 419 and 424 attended visits at 6, 12, 18 and 24 months, respectively. The most commonly prescribed therapy was TPD (single-agent; 64.5%), then bisphosphonates and other anti-resorptives (33.3%). A combination of different oral treatments was given to 22.5% of the patients. Overall treatment adherence at 24 months was 65.7%. In a post-hoc analysis, the overall incidence of new clinical vertebral and non-vertebral fractures in the total treated population was, respectively, 4.7% and 2.3% in the first 6 months; 1.8% and 1.6% in the 6-12 month period; 2.9% and 1.4% in the 12-18 month period; and 2.2% and 1.0% in the 18-24 month period. Conclusion In patients with very severe osteoporosis, the risk of new vertebral and non-vertebral fractures declined after the first 6 months and remained low throughout the study.
