The article deals with the application of the environmental damage assessment procedure and H&V index II method to the diesel fuel tank storage facility in a sand mining company using a case study. The procedures enabled the researchers to semi-quantitatively assess the operated diesel fuel tank’s impact on the selected environmental components and the possible damage risk by the leakage of stored fuel. It was discovered, by assessing the operating conditions, the state of the environment at the mining facility, and the risk of a diesel fuel leakage accident, that it is not necessary for the company to implement further steps in the field of environmental damage minimization. The H&V index II method examined both the impacts of diesel fuel leakage on soil, biotic component, groundwater, surface water, and the impact of flammable substances on the biotic environmental component in six steps. Slight or significant impacts were identified depending on the environmental component during the determination of the accident severity. The accident severity, together with the estimated probability, was plotted in the risk matrix which resulted in acceptable risks for all affected environmental components. The results of both approaches showed that the diesel fuel leakage in the mining company represents an acceptable environmental risk in relation to the countermeasures implemented so far.

In terms of service provision, the electricity sector is the most important critical infrastructure sector, on the supply of which the vast majority of society and its basic vital functions depend. Extensive disruption of these supplies would have negative effects not only on basic human needs, but also on the economy and security of the state. For this reason, it is necessary to ensure permanent and comprehensive monitoring of the infrastructure elements resilience level, especially against threats with a multispectral impact on several areas of security. For this reason, the authors of the article developed the Converged Resilience Assessment (CRA) method, which enables advanced assessment of the electricity critical infrastructure elements resilience from the converged security point of view. Converged security in this case combines (converges) physical, cyber and operational security into a complementary unit. This reflects the integral determinants of resilience across related areas of security/safety. The CRA method focuses mainly on information and situation management, which integrates and correlates information (signals) from systems and sensors in order to obtain an overview of the situation and the subsequent effective management of its solution. The practical use of the proposed method is demonstrated on a selected element of the Czech Republic transmission system. The CRA method is currently embodied in a functional sample that has been piloted on several TSO elements. Further development of this method is seen mainly in fulfilling the logic of network infrastructure and reflection between elementary and intersectoral links in the context of synergistic and cascading effects in a broader context.

The paper focuses on risk sources under no legislative pressure in the field of prevention of major accidents. Despite this, they can represent significant sources of risk of accidents. The aim of the paper is to present the results of the risk assessment associated with the operation of enterprises not regulated by the SEVESO III Directive (the so-called subliminal enterprises), to provide information on possible operational problems and to verify the applicability of recognized risk analysis methods for these specific sources of risk. Last but not least, its purpose is to point out that subliminal enterprises, due to their location close to residential areas or areas with a high concentration of population, pose a serious risk to the population. The paper summarizes the results of the quantitative risk assessment of a specific enterprise not included in the Seveso Directive – a filling station. Filling stations are frequently located in built-up areas with a dense coefficient of habitability. Due to their number, location (e.g. close to residential areas), frequency of occurrence of persons in the area and handling of dangerous substances during normal operation, they can have negative or even tragic consequences to the life and health of the population. Due to the non-existent risk assessment methodology for enterprises with subliminal quantities of dangerous substances and the lack of a systematic search for risk sources, a risk assessment procedure for these companies is designed.

The European gas network currently includes approximately 200,000 km high pressure transmission and distribution pipelines. The needs and requirements of this network are focused on risk-based security asset management, impacts and cascading effects of cyber-physical attacks on interdependent and interconnected European Gas grids. The European SecureGas project tackles these issues by implementing, updating, and incrementally improving extended components, which are contextualized, customized, deployed, demonstrated and validated in three business cases, according to scenarios defined by the end-users. Just validation is considered to be a key end activity, the essence of which is the evaluation of the proposed solution to determine whether it satisfies specified requirements. Therefore, the chapter deals with the validation strategy that can be implemented for the verification of these objectives and evaluation of technological based solutions which aim to strengthen the resilience of the European gas network.

The robustness of the critical infrastructure system is determined by the validity and vulnerability of its individual elements and the links between them. For this reason, these elements are the basic building blocks of the system, which must be protected from security threats. The level of their physical protection is currently assessed through quantitative models of physical protection systems (PPS). However, these models are now obsolete because they do not allow the integration of new dynamic parameters. For this reason, the article focuses on the implementation of the Bayesian updating method in the PPS model development, which will allow the exact involvement of new information obtained during the PPS life. The application of Bayesian updating to software tools allows recalculation of individual values of input parameters and thus obtaining increasingly realistic information about the efficiency of the PPS system. This information can be used to modify the structure and adopt protection measures in relation to the set limit values of the output parameters of the security assessment. The created use case shows an example of the procedure of developing and assessing a quantitative PPS model on a selected element of water critical infrastructure using software support.

The purpose of this paper is to present the development of a qualitative approach to environmental risk assessment (QAERA) in transport. The approach is described as a model developed for the future software tool which will be utilizable as a risk decision support system. The basic part is aimed on developing a quantitative environmental risk assessment. Thus, this paper describes a set of 6 pillars of safety and security. Accordingly, the paper contains both chosen safety and security indicators and selected criteria for assessing the risk of launching the environmental change of global model thinking in the transport sector. The environmental risk assessment as a global model of thinking was originally based on historical experience but, nowadays, it is changing. Based on new expert knowledge, more precisely, on input of new global data, paper displays an environmental risk assessment with actual interpretation. The discussion of the paper is oriented to support research results, a new knowledge-oriented approach to global climate changes, using suitable risk assessment methods and technics. The result of the paper is a new approach for the modeling of environmental risk assessment in the transport sector.

Road transport is a key means of transporting people and cargo on land. Its particular advantages are speed and operability, which are balanced, however, by dependence on road infrastructure. Road infrastructure reliability is an important factor in its functioning. If some elements of road infrastructure are disrupted or fail, the function of dependent infrastructures, such as the integrated rescue system or industry, are also impaired and may fail. These important elements of road infrastructure should be identified as critical and be given greater attention when identifying weaknesses and implementing subsequent security measures. This article introduces the Identifying Critical Elements of Road Infrastructure (ICERI) method, which was designed to make use of Cascading Impact Assessments (CIA). The use of CIA allows critical elements to be identified through impact escalation analysis. These impacts can therefore be monitored not only in road transport infrastructure but also across the entire critical infrastructure system.

The Electric Power Infrastructure Sector is a uniquely critical sector among other critical infrastructures. Disruptions to or failures of its functions would result in extensive effects, not only on society itself but also on all of the (other) dependent critical infrastructure sectors. The key areas of electric power supply systems that demonstrate the greatest vulnerability to terrorist attacks include the following areas of vulnerability: physical vulnerability, cyber vulnerability and personnel vulnerability. Considerable attention is devoted to the problems and issues of external anthropogenic threats (e.g. terrorism). Internal intentional anthropogenic threats represent an almost neglected sector in the field of security research. Based on this fact, this article studies the issues of threats to and by personnel in the electric power critical infrastructure sector and their influence and effect on dependent critical infrastructure sectors. Attention is especially given to defining these threats and their (further) categorization into two groups: physical and cyber threats. Equally, this article also highlights the impacts of personnel threats in dependent critical infrastructure sectors. The main part of this paper focuses on security measures that can be used to minimize the potential impact of personnel threats. This especially concerns (1) assessing the resilience of elements in the electric power critical infrastructure sector to personnel threats, (2) defining the requirements for personnel security, and (3) the use of standard technical and innovative technologies to monitor and assess the activities of authorized or non-authorized persons.

The paper Criticality Assessment of Railway Bridges presents current research results at the University of Zilina. Transport as part of the critical infrastructure of the state is one of the key sectors. Rail transport is one of the critical infrastructure subsectors, consisting of point, line and area objects. Rail bridges and tunnels are currently one of the most important railway infrastructures. Their disruption or failure could lead to the cessation of rail transport on the route involved and the consequent complicated provision of alternative transport. In the case of international routes, this situation would lead to significant economic losses and a negative impact on the transport serviceability of residents and freight forwarders. In order to maintain the continuity of railway transport on the most important routes, it is appropriate to identify and evaluate all critical bridges in a timely manner and to give them increased protection against identified threats. Based on this, the paper presents a tool for criterion-based assessment of the railway bridges criticality. The tool is based on the evaluation of technical and economic parameters. Technical parameters are e.g. the bridging height, the length of the bridge object, the load of the bridge object, the number of pillars, the material of the bridge object or the age of the bridge object. On the other hand, the economic parameters are focused on the economic losses or the intensity of traffic on the bridge object from the point of view of the economy or the number of transported persons. The combination of these parameters allows the evaluator to analyse the criticality of railway bridges both in terms of their structure and social contribution.

In the last ten years, considerable attention has been paid to analysing and assessing the criticality of railway infrastructure elements. Publications on the subject mostly assess elements only from a certain point of view, such as purpose, reliability or risk. This leads to only a partial assessment of criticality without continuous correlation, which may result some critical elements of the system being omitted. The article introduces the railway infrastructure criticality assessment tool (RICA tool), which was created to evaluate the criticality of railway infrastructure elements in all aspects. The integral approach of the tool lies in comprehensively assessing the technical and process factors of rail transport. The criticality of railway infrastructure elements is therefore assessed not only in terms of the relevance and resilience of elements but also their interdependence, substitutability, risk and impact.

Critical infrastructure is a system that consists of civil infrastructures in which disruption or failure would have a serious impact on the lives and health of the population. It includes, for example, electricity, oil and gas, water supplies, communications and emergency or healthcare services. It is therefore important that technical resilience and organisational resilience is provided continuously and at a high level by the owners and operators of these civil infrastructures. Organisational resilience management mainly consists of continuously assessing determinants in order to identify weak points early so that adequate security measures can be taken to strengthen them. In the context of the above, the article presents a method for Assessing and Strengthening Organisational Resilience (ASOR Method) in a critical infrastructure system. The essence of this method lies in defining the factors that determine organisational resilience and the process of assessing and strengthening organisational resilience. The method thus allows weaknesses to be identified and the subsequent quantification of positive impacts that strengthen individual factors in organisational resilience. A benefit from applying this method is minimizing the risk and subsequent adverse impact on society of critical infrastructure system disruption or failure. The article also contributes to achieving the UN Sustainable Development Goal 9, namely Building Resilient Infrastructure. The ASOR method namely contributes to the development of quality, reliable, sustainable and resilient infrastructure, including regional and trans-border infrastructure. Finally, the article presents the results of this method’s practical application on a selected electricity critical infrastructure entity in the Slovak Republic.

The resilience of elements in a critical infrastructure system is a major factor determining the reliability of services and commodities provided by the critical infrastructure system to society. Resilience can be viewed as a quality which reduces the vulnerability of an element, absorbs the effects of disruptive events, enhances the element's ability to respond and recover, and facilitates its adaptation to disruptive events similar to those encountered in the past. In this respect, resilience assessment plays an important role in ensuring the security and reliability of not only these elements alone, but also of the system as a whole. The paper introduces the CIERA methodology designed for Critical Infrastructure Elements Resilience Assessment. The principle of this method is the statistical assessment of the level of resilience of critical infrastructure elements, involving a complex evaluation of their robustness, their ability to recover functionality after the occurrence of a disruptive event and their capacity to adapt to previous disruptive events. The complex approach thus includes both the assessment of technical and organizational resilience, as well as the identification of weak points in order to strengthen resilience. An example of the application of the CIERA method is presented in the form of a case study focused on assessing the resilience of a selected element of electrical energy infrastructure.

Crisis management must provide data to allow for real-time decision-making. Accurate data is especially needed to minimize the risk of critical infrastructure failure. Research into the possible impacts of critical infrastructure failure is a part of developing a functional and secure infrastructure for each nation state. Road transport is one such sector that has a significant impact on its functions. When this fails, there may be a cascading spread of impacts on the energy, health, and other sectors. In this regard, this paper focuses on the dynamic modeling of the impacts of critical road infrastructure failures. It proposes a dynamic modeling system based on a stochastic approach. Its essence is the macroscopic model-based comparative analysis of a road with a critical element and detour roads. The outputs of this system are planning documents that determine the impacts of functional parameter degradation on detour roads—not only applicable in decision-making concerning the selection of the optimal detour road, but also as a support mechanism in minimising possible risks. In this article we aim to expand the extent of knowledge in the Crisis management and critical infrastructure protection in the road transport sector fields.

Due to its costly and time-consuming nature and a wide range of passive barrier elements and tools for their breaching, testing the delay time of passive barriers is only possible as an experimental tool to verify expert judgements of said delay times. The article focuses on the possibility of creating and utilizing a new method of acquiring values of delay time for various passive barrier elements using expert judgements which could add to the creation of charts where interactions between the used elements of mechanical barriers and the potential tools for their bypassing would be assigned a temporal value. The article consists of basic description of methods of expert judgements previously applied for making prognoses of socio-economic development and in other societal areas, which are called soft system. In terms of the problem of delay time, this method needed to be modified in such a way that the prospective output would be expressible by a specific quantitative value. To achieve this goal, each stage of the expert judgements was adjusted to the use of suitable scientific methods to select appropriate experts and then to achieve and process the expert data. High emphasis was placed on evaluation of quality and reliability of the expert judgements, which takes into account the specifics of expert selection such as their low numbers, specialization and practical experience.

The paper focuses on the problem of importance/significance elements evaluation in the railway transport infrastructure sub-systems. It contains main features of the proposed theoretical approach to the significance assessment of the key typological elements of railways infrastructure. The research also attempted to design an effective methodology, which allows assessing the significance of infrastructure objects. The purpose of the multi-criteria assessment of selected sections and typological objects is to select the most significant/important ones from the point of view of maintaining the railway operability. The selection is conducted using the assessment of a section or an object, following the pre-defined criteria. The developed methodology should help to set a group of potential elements of critical infrastructure in the railway sub-sector.

This article focuses on the issue of assessing the cascading effects of critical energy and transport infrastructure elements at the fundamental level. The introductory part deals with the typology of failures and their impacts, which spread through the critical infrastructure system. At this stage, the paper presents current approaches to assessing the cascading effects and, in particular, addresses a newly developed assessment methodology. The following part defines the initial conditions of assessment and describes selected elements from the areas of energy and rail transport to which the methodology will be subsequently applied. The main part of the article is a case study of the proposed methodology, assessing the cascading effects by calculating the value of their risks, depending on the resilience and correlation of the rated elements.
