Opis:
The paper presents an application of an RT-family trust management language as a basis for an access control model. The discussion concerns a secure workstation running multiple virtual machines used to process sensitive information from multiple security domains, providing strict separation of the domains. The users may act in several different roles, with different access rights. The inference mechanisms of the language are used to translate credentials allowing users to access different functional domains, and assigning virtual machines to these domains into clear rules, regulating the rights of a particular user to a particular machine, taking into account different periods of validity of different credentials. The paper also describes a prototype implementation of the model.

Opis:
An emergency situation often occurs as a result of unpredictable events, and as a consequence, existing communications may either get collapsed or congested. The aim of the Communication Security Monitoring and Control Centre (CSMCC) solution proposed in SECRICOM is to provide a suitable security framework that enables the development of security service. These services give response to individuals and institutions operating in heterogeneous communication infrastructures, when responding to major incidents. In the light of this objective, a Security Model has been designed facilitating the measurement of operators' and end customers' confidence in the security of the communication infrastructure, and addressing security challenges in terms of a distributed and heterogeneous solution. The proposed Security Model has been supported by the Security Middleware Service and Framework, which is responsible for measuring, documenting and maintaining the security level of the services provided by the SECRICOM communication system.
Sytuacje kryzysowe występują zazwyczaj w wyniku nieprzewidzianych wydarzeń, co implikuje problemy z niedostępnością lub przeciążeniem systemu łączności. Zadaniem zaproponowanego w ramach projektu SECRICOM rozwiązania Communication Security Monitoring and Control Centre (CSMCC) jest bezpieczeństwo usług z nim związanych. Usługi te są kierowane do podmiotów obsługujących różnorodne infrastruktury telekomunikacyjne na potrzeby zarządzania kryzysowego. W tym celu opracowano model bezpieczeństwa ułatwiający pomiar bezpieczeństwa infrastruktury komunikacyjnej oraz wspierający rozwiązywanie problemów wynikających z heterogenicznych i rozproszonych rozwiązań. Zaproponowany model jest wspierany przez rozwiązanie Security Middleware Service and Framework, który jest odpowiedzialny za mierzenie, dokumentację oraz utrzymanie poziomu bezpieczeństwa usług oferowanych przez system SECRICOM.

Opis:
The paper presents a proposal for the data security model to protect the cadastral information recorded in the databases of real estate in Poland. The model was developed for the implementation of multi-purpose cadastral tasks. The problem has been considered from the point of view of the smooth functioning of the real estate market. Reliability of the real estate market is guaranteed by the full, accurate, easily available and current cadastral data. The latter is an important piece of information about the area or land, essential for the implementation of most of the real estate management processes. The publication indicates obligatory and optional sources of cadastral information. The basis for the model of cadastral data security system is the compatibility of the assumptions between the said model and the applicable law. The model contains four types of disclosure status for cadastral data (confidential information, public information, incomplete public information, non-confidential information requiring a license). The status was adjusted to specified groups of users of the multipurpose cadastre. The aforementioned groups are based on the entities, acting within the real estate market in Poland. The security model presented herewith assumes a full transition to computer storage media, including the descriptive information and spatial databases, contained in the multi-purpose cadastre, as well as full interoperability of the data collected therein.
W publikacji przedstawiono propozycję modelu zabezpieczeń informacji katastralnej, rejestrowanej w bazach danych o nieruchomościach w Polsce. Model opracowano pod kątem realizacji zadań katastru wielozadaniowego. Problem ten rozpatrzono z punktu widzenia sprawnego funkcjonowania rynku nieruchomości. Gwarancją rzetelności rynku nieruchomości jest pełna, dokładna, łatwo osiągalna i aktualna informacja katastralna. Informacja ta stanowi istotny element informacji o terenie, niezbędny w realizacji większości procesów gospodarki nieruchomościami. W publikacji wskazano obligatoryjne oraz fakultatywne źródła informacji katastralnej. Podstawą opracowanego modelu zabezpieczeń systemu katastralnego jest zgodność założeń niniejszego modelu z obowiązującymi przepisami prawa. Model zawiera cztery rodzaje statusu jawności informacji katastralnej (informacje poufne, informacje jawne, informacje jawne niepełne, informacje jawne wymagające licencji). Status ten dostosowano do wyszczególnionych grup użytkowników katastru wielozadaniowego. Grupy te przyjęto w oparciu o podmioty występujące na rynku nieruchomości w Polsce. Prezentowany model zabezpieczeń zakłada pełne przejście na komputerowe nośniki danych, w zakresie informacji opisowej i przestrzennej, wszystkich baz danych wchodzących w skład katastru wielozadaniowego oraz pełną interoperacyjność gromadzonych w nich danych.

Opis:
The subject of this study is the non-repudiation security service for network communication using TCP/IP stack. Generated evidence, as well as decision-making process of registering a given event, are context-aware. Non-repudiation is equipped with context-awareness by using widely utilized network tools. The aim of this paper is to present timing results for selected tools execution and to complete the evidence generation time. In some applications it is crucial to gather evidence data as fast as possible because of the rapidly changing network environment. For such situations, in case of prolonged execution time, an output from a tool might imprecisely describe the contextual situation from the time of the occurrence of an event.

Purpose: The scope of interactive information processed and exchanged through cyberspace has grown exponentially. Therefore, there is a need to develop cybersecurity that protects this space against both internal and external threats, as well as to work out an appropriate reporting system on the cybersecurity model operating in the company. The aim of the paper is to identify and assess the disclosures on cybersecurity and cyber risk in the integrated and management reports of selected companies listed on the Warsaw Stock Exchange. Methodology: The study focused on the integrated and management reports of 17 selected companies identified as operators of so-called key services. The representative sample was chosen through purposive sampling. This process was preceded by a preliminary analysis of companies listed in the WIG 30 Index, drawing on the number of integrated reports prepared by the operators of key services. The research involved an analysis of the literature and legal regulations, as well as the structure and scope of information on cybersecurity reported by the surveyed companies, along with the deductive method. The results of the analysis showed that only some companies present information on existing cyber risks and cybersecurity, while information is scattered in different parts of the business reports and non-comparable due to the lack of a unified data structure. It was noted that the reports do not contain detailed information on the activities in the field of cybersecurity, which makes it impossible to perform a multifaceted and multisectoral assessment of the results reported by the entities. Originality: The paper builds on and thus complements the scientific achievements in the field of non-financial reporting, including the business model, by identifying the shortcomings related to reporting on how to protect companies against the risk related to cyber threats in the reports to date. The study also confirms the need to improve the content of business reports with quantitative and qualitative information in this regard

This article presents fundamental issues concerning the description of the security system of an organization understood as an entirety composed of people equipped with tools, machines and materials, which are connected with one another by a specific bond and between which there are relations connected to ensuring an undisturbed existence and creating opportunities for development. The description of security systems is a complex undertaking. It is a consequence of its complexity, which is primarily a result of the set of relations between organizational elements. They include: accumulation (expressed in the number of hierarchical levels, range (related to the number of subordinations and dependencies), spread (associated with the number of elements subordinate to a single superior at each organizational level), organizational cohesiveness (connected to the mutual structural and functional dependencies between organizational elements due to performed tasks), information links (reflecting the channels and network of information flow), as well as the division of powers (associated with the right to make decisions), and division of duties (related to the relationship between organizational elements). The complexity of the description of security systems is also determined by the activity of the organization’s security systems, which can be divided into: material (concerning the types of activities), temporal (related to the order of its conduct in a specific time), and spatial (connected to conducting activities in specific places). The description of security systems is only possible through the use of: appropriate methodological procedures and a systemic approach, as characterized within the constraints resulting from the expression formula. This paper also indirectly addresses the determinants of the description of security systems. These are: up-to-date knowledge, concreteness and reliability of the description and sufficient detail.

The study examined the impact of climate variability on yield of maize and yam in Cross River State, Nigeria. The specific objectives of the study were to determine the long-run and short-run impact of climate variability factors on yields of maize and yam. Data were sourced from the Nigerian Meteorological Agency (NiMeT) and Cross River State Ministry of Agriculture spanning from 1990-2016. Data obtained were analyzed using inferential statistics. Precisely, the model was estimated by the Ordinary Least Squares (OLS) multiple regression technique, which is within the Autoregressive Distributed Lag Bound approach and error correction testing framework. Both model-1 (maize yield) and model-2 (yam yield) passed through the conditions of the diagnostics and stability test. The study revealed that climate variables had a significant impact on maize yield both in the long and short-run. Based on the findings, it was concluded that proactive measures should be put in place to aid crop farmers adapt to the prevailing and looming threats of climate variability for the purpose of attaining the State’s food security balance sheet. To sustain this drive, an institutional and infrastructural support system is advocated in order to meet one of the goals of sustainable development agenda of the United Nations. Policy recommendations on how to cushion the impact of climate variability on the prescribed crops have been appropriately cited.

This paper presents research of different classes of attacks against complex technical objects. Attacks are differentiated into different classes on the basis of analysis of attack features which reflect the possible methods of attack interaction with the security system. The developed methods of formal description of attacks and defense methods on the level of their logical approximation allow describing tasks of withstanding attacks for defense tools with enough certainty. Thanks to the proposed interpretation of attack interaction with a defense object and defense tools, it has become possible to determine approaches to the extension of the defense system by adding new tools oriented towards withstanding new attacks.

The paper presents a forecast of the economic security of the inter-industry complex through the construction of a simulation model. The authors considered the possibility of using an econometric model in predicting the level of economic security of the inter-industry complex. The goal was to form a definition of the "inter-industry complex", as well as to study the issues of conceptual and fundamental methods of econometric modeling and forecasting the development of regional industry markets in dynamics. A range of issues related to the main components of economic security in the inter-industry complex has been allocated for scientific work in order to analyze the impact of the components of economic security on the integral indicator. The paper uses a methodology for predicting the structural and spatial-temporal dynamics of interbranch complexes, which includes new and refined methods of modeling and forecasting. As a result, the authors proposed the definition of "inter-industry complex", "economic security in the inter-industry complex", as well as the general provisions of the methodology for econometric modeling and forecasting the level of economic security of the inter-industry complex. The paper presents a full-scale simulation model that allows you to set, evaluate and make a decision using large nonlinear data. This kind of system contains dynamic and retarded data, which makes it possible to apply econometric modeling in automatic calculation.

Opis:
In the digital society, states’ information security has become one of the key elements of ensuring the competitiveness and sustainable development of the state, guaranteeing its integrity and security in general. An important component of state security is the internal security of the state, which must ensure the personal and public safety of its citizens. Modern Ukraine is building a new system of criminal justice, which requires a new information system for risk assessment and support for optimal decision-making. Today, applied research and the development of information and analytical software for the internal security of the state have acquired a special meaning. In the paper, there is built a set of models for providing operational information for decision-making in criminal justice. This is a cluster model for creating criminal profiles of convicts, and a scoring model for identifying individual characteristics of criminals that have the greatest impact on their propensity to reoffend. The obtained models can provide reliable support for decision-making in the field of criminal justice and become part of the information support system for the internal security of Ukraine in general.

Issues relating to food availability, accessibility, affordability, and utilization remain of paramount importance among rural households. In order to formulate or implement relevant food security programs in rural areas, it is essential to have a deep understanding of the food security status of rural households. This study sought to determine the prevalence of food insecurity among rural households in the Eastern Cape Province, as well as its key socioeconomic and demographic factors. A cross-sectional study was carried out on 240 households using questionnaires about food security. A convenience sampling method was used to collect data, along with a structured questionnaire. Descriptive statistics and binary logistic regression were used to analyze the data. The binary logistic regression model revealed that age of household head, education level of household head, access to credit, household income, and household size were all associated with food security status. Thus, this study recommends that the government at all levels (local, state, and federal) have an adequate budget allocated to increasing awareness of the benefits of participating in farming to improve the livelihood outcomes of households
