Bhosale, Pushparaj, Kastner, Wolfgang, Sauter, Thilo.  2022.  Automating Safety and Security Risk Assessment in Industrial Control Systems: Challenges and Constraints. 2022 IEEE 27th International Conference on Emerging Technologies and Factory Automation (ETFA). :1–4.
Currently, risk assessment of industrial control systems is static and performed manually. With the increased convergence of operational technology and information technology, risk assessment has to incorporate a combined safety and security analysis along with their interdependency. This paper investigates the data inputs required for safety and security assessments, also if the collection and utilisation of such data can be automated. A particular focus is put on integrated assessment methods which have the potential for automation. In case the overall process to identify potential hazards and threats and analyze what could happen if they occur can be automated, manual efforts and cost of operation can be reduced, thus also increasing the overall performance of risk assessment.

Hyder, Burhan, Majerus, Harrison, Sellars, Hayden, Greazel, Jonathan, Strobel, Joseph, Battani, Nicholas, Peng, Stefan, Govindarasu, Manimaran.  2022.  CySec Game: A Framework and Tool for Cyber Risk Assessment and Security Investment Optimization in Critical Infrastructures. 2022 Resilience Week (RWS). :1–6.
Cyber physical system (CPS) Critical infrastructures (CIs) like the power and energy systems are increasingly becoming vulnerable to cyber attacks. Mitigating cyber risks in CIs is one of the key objectives of the design and maintenance of these systems. These CPS CIs commonly use legacy devices for remote monitoring and control where complete upgrades are uneconomical and infeasible. Therefore, risk assessment plays an important role in systematically enumerating and selectively securing vulnerable or high-risk assets through optimal investments in the cybersecurity of the CPS CIs. In this paper, we propose a CPS CI security framework and software tool, CySec Game, to be used by the CI industry and academic researchers to assess cyber risks and to optimally allocate cybersecurity investments to mitigate the risks. This framework uses attack tree, attack-defense tree, and game theory algorithms to identify high-risk targets and suggest optimal investments to mitigate the identified risks. We evaluate the efficacy of the framework using the tool by implementing a smart grid case study that shows accurate analysis and feasible implementation of the framework and the tool in this CPS CI environment.

Feng, Jiayi.  2022.  Generative Adversarial Networks for Remote Sensing. 2022 2nd International Conference on Big Data, Artificial Intelligence and Risk Management (ICBAR). :108–112.
Generative adversarial networks (GANs) have been increasingly popular among deep learning methods. With many GANs-based models developed since its emergence, among which are conditional generative adversarial networks, progressive growing of generative adversarial networks, Wasserstein generative adversarial networks and so on. These frameworks are currently widely applied in areas such as remote sensing cybersecurity, medical, and architecture. Especially, they have solved problems of cloud removal, semantic segmentation, image-to-image translation and data argumentation in remote sensing. For example, WGANs and ProGANs can be applied in data argumentation, and cGANs can be applied in semantic argumentation and image-to-image translation. This article provides an overview of structures of multiple GANs-based models and what areas they can be applied in remote sensing.

Choucri, Nazli, Agarwal, Gaurav.  2022.  Analytics for Cybersecurity Policy of Cyber-Physical Systems. 2022 IEEE International Symposium on Technologies for Homeland Security (HST). :1—7.
Guidelines, directives, and policy statements are usually presented in “linear” text form - word after word, page after page. However necessary, this practice impedes full understanding, obscures feedback dynamics, hides mutual dependencies and cascading effects and the like-even when augmented with tables and diagrams. The net result is often a checklist response as an end in itself. All this creates barriers to intended realization of guidelines and undermines potential effectiveness. We present a solution strategy using text as “data”, transforming text into a structured model, and generate network views of the text(s), that we then can use for vulnerability mapping, risk assessments and note control point analysis. For proof of concept we draw on NIST conceptual model and analysis of guidelines for smart grid cybersecurity, more than 600 pages of text.
Carvalho, Gonçalo, Medeiros, Nadia, Madeira, Henrique, Cabral, Bruno.  2022.  A Functional FMECA Approach for the Assessment of Critical Infrastructure Resilience. 2022 IEEE 22nd International Conference on Software Quality, Reliability and Security (QRS). :672—681.
The damage or destruction of Critical Infrastructures (CIs) affect societies’ sustainable functioning. Therefore, it is crucial to have effective methods to assess the risk and resilience of CIs. Failure Mode and Effects Analysis (FMEA) and Failure Mode Effects and Criticality Analysis (FMECA) are two approaches to risk assessment and criticality analysis. However, these approaches are complex to apply to intricate CIs and associated Cyber-Physical Systems (CPS). We provide a top-down strategy, starting from a high abstraction level of the system and progressing to cover the functional elements of the infrastructures. This approach develops from FMECA but estimates risks and focuses on assessing resilience. We applied the proposed technique to a real-world CI, predicting how possible improvement scenarios may influence the overall system resilience. The results show the effectiveness of our approach in benchmarking the CI resilience, providing a cost-effective way to evaluate plausible alternatives concerning the improvement of preventive measures.

The digital transformation brought on by 5G is redefining current models of end-to-end (E2E) connectivity and service reliability to include security-by-design principles necessary to enable 5G to achieve its promise. 5G trustworthiness highlights the importance of embedding security capabilities from the very beginning while the 5G architecture is being defined and standardized. Security requirements need to overlay and permeate through the different layers of 5G systems (physical, network, and application) as well as different parts of an E2E 5G architecture within a risk-management framework that takes into account the evolving security-threats landscape. 5G presents a typical use-case of wireless communication and computer networking convergence, where 5G fundamental building blocks include components such as Software Defined Networks (SDN), Network Functions Virtualization (NFV) and the edge cloud. This convergence extends many of the security challenges and opportunities applicable to SDN/NFV and cloud to 5G networks. Thus, 5G security needs to consider additional security requirements (compared to previous generations) such as SDN controller security, hypervisor security, orchestrator security, cloud security, edge security, etc. At the same time, 5G networks offer security improvement opportunities that should be considered. Here, 5G architectural flexibility, programmability and complexity can be harnessed to improve resilience and reliability. The working group scope fundamentally addresses the following: •5G security considerations need to overlay and permeate through the different layers of the 5G systems (physical, network, and application) as well as different parts of an E2E 5G architecture including a risk management framework that takes into account the evolving security threats landscape. •5G exemplifies a use-case of heterogeneous access and computer networking convergence, which extends a unique set of security challenges and opportunities (e.g., related to SDN/NFV and edge cloud, etc.) to 5G networks. Similarly, 5G networks by design offer potential security benefits and opportunities through harnessing the architecture flexibility, programmability and complexity to improve its resilience and reliability. •The IEEE FNI security WG's roadmap framework follows a taxonomic structure, differentiating the 5G functional pillars and corresponding cybersecurity risks. As part of cross collaboration, the security working group will also look into the security issues associated with other roadmap working groups within the IEEE Future Network Initiative.

Xiao, Wenfeng.  2022.  Research on applied strategies of business financial audit in the age of artificial intelligence. 2022 18th International Conference on Computational Intelligence and Security (CIS). :1–4.
Artificial intelligence (AI) was engendered by the rapid development of high and new technologies, which altered the environment of business financial audits and caused problems in recent years. As the pioneers of enterprise financial monitoring, auditors must actively and proactively adapt to the new audit environment in the age of AI. However, the performances of the auditors during the adaptation process are not so favorable. In this paper, methods such as data analysis and field research are used to conduct investigations and surveys. In the process of applying AI to the financial auditing of a business, a number of issues are discovered, such as auditors' underappreciation, information security risks, and liability risk uncertainty. On the basis of the problems, related suggestions for improvement are provided, including the cultivation of compound talents, the emphasis on the value of auditors, and the development of a mechanism for accepting responsibility.

Kandera, Branislav, Holoda, Šimon, Jančík, Marián, Melníková, Lucia.  2022.  Supply Chain Risks Assessment of selected EUROCONTROL’s surveillance products. 2022 New Trends in Aviation Development (NTAD). :86–89.
Cybersecurity is without doubt becoming a societal challenge. It even starts to affect sectors that were not considered to be at risk in the past because of their relative isolation. One of these sectors is aviation in general, and specifically air traffic management. Nowadays, the cyber security is one of the essential issues of current Air Traffic Systems. Compliance with the basic principles of cyber security is mandated by European Union law as well as the national law. Therefore, EUROCONTROL as the provider of several tools or services (ARTAS, EAD, SDDS, etc.), is regularly conducting various activities, such as the cyber-security assessments, penetration testing, supply chain risk assessment, in order to maintain and improve persistence of the products against the cyber-attacks.
Domukhovskii, Nikolai.  2022.  Optimal Attack Chain Building Algorithm. 2022 Ural-Siberian Conference on Biomedical Engineering, Radioelectronics and Information Technology (USBEREIT). :317–319.
Traditional risk assessment process based on knowledge of threat occurrence probability against every system’s asset. One should consider asset placement, applied security measures on asset and network levels, adversary capabilities and so on: all of that has significant influence on probability value. We can measure threat probability by modelling complex attack process. Such process requires creating an attack tree, which consist of elementary attacks against different assets and relations between elementary attacks and impact on influenced assets. However, different attack path may lead to targeted impact – so task of finding optimal attack chain on a given system topology emerges. In this paper method for complex attack graph creation presented, allowing automatic building various attack scenarios for a given system. Assuming that exploits of particular vulnerabilities represent by independent events, we can compute the overall success probability of a complex attack as the product of the success probabilities of exploiting individual vulnerabilities. This assumption makes it possible to use algorithms for finding the shortest paths on a directed graph to find the optimal chain of attacks for a given adversary’s target.

The world’s most important industrial economy is particularly vulnerable to both external and internal threats, such as the one uncovered in Supervisory Control and Data Acquisition (SCADA) and Industrial Control Systems (ICS). Upon those systems, the success criteria for security are quite dynamic. Security flaws in these automated SCADA systems have already been discovered by infiltrating the entire network in addition to reducing production line hazards. The objective of our review article is to show various potential future research voids that recent studies have, as well as how many methods are available to concentrate on specific aspects of risk assessment of manufactured systems. The state-of-the-art methods in cyber security risk assessment of SCADA systems are reviewed and compared in this research. Multiple contemporary risk assessment approaches developed for or deployed in the settings of a SCADA system are considered and examined in detail. We outline the approaches’ main points before analyzing them in terms of risk assessment, conventional analytical procedures, and research challenges. The paper also examines possible risk regions or locations where breaches in such automated SCADA systems can emerge, as well as solutions as to how to safeguard and eliminate the hazards when they arise during production manufacturing.

Halabi, Talal, Abusitta, Adel, Carvalho, Glaucio H.S., Fung, Benjamin C. M..  2022.  Incentivized Security-Aware Computation Offloading for Large-Scale Internet of Things Applications. 2022 7th International Conference on Smart and Sustainable Technologies (SpliTech). :1–6.

With billions of devices already connected to the network's edge, the Internet of Things (IoT) is shaping the future of pervasive computing. Nonetheless, IoT applications still cannot escape the need for the computing resources available at the fog layer. This becomes challenging since the fog nodes are not necessarily secure nor reliable, which widens even further the IoT threat surface. Moreover, the security risk appetite of heterogeneous IoT applications in different domains or deploy-ment contexts should not be assessed similarly. To respond to this challenge, this paper proposes a new approach to optimize the allocation of secure and reliable fog computing resources among IoT applications with varying security risk level. First, the security and reliability levels of fog nodes are quantitatively evaluated, and a security risk assessment methodology is defined for IoT services. Then, an online, incentive-compatible mechanism is designed to allocate secure fog resources to high-risk IoT offloading requests. Compared to the offline Vickrey auction, the proposed mechanism is computationally efficient and yields an acceptable approximation of the social welfare of IoT devices, allowing to attenuate security risk within the edge network.

Clausen, Marie, Schütz, Johann.  2022.  Identifying Security Requirements for Smart Grid Components: A Smart Grid Security Metric. 2022 IEEE 20th International Conference on Industrial Informatics (INDIN). :208—213.
The most vital requirement for the electric power system as a critical infrastructure is its security of supply. In course of the transition of the electric energy system, however, the security provided by the N-1 principle increasingly reaches its limits. The IT/OT convergence changes the threat structure significantly. New risk factors, that can lead to major blackouts, are added to the existing ones. The problem, however, the cost of security optimizations are not always in proportion to their value. Not every component is equally critical to the energy system, so the question arises, "How secure does my system need to be?". To adress the security-by-design principle, this contribution introduces a Security Metric (SecMet) that can be applied to Smart Grid architectures and its components and deliver an indicator for the "Securitisation Need" based on an individual risk assessment.
Park, Sihn-Hye, Lee, Seok-Won.  2022.  Threat-driven Risk Assessment for APT Attacks using Risk-Aware Problem Domain Ontology. 2022 IEEE 30th International Requirements Engineering Conference Workshops (REW). :226–231.
Cybersecurity attacks, which have many business impacts, continuously become more intelligent and complex. These attacks take the form of a combination of various attack elements. APT attacks reflect this characteristic well. To defend against APT attacks, organizations should sufficiently understand these attacks based on the attack elements and their relations and actively defend against these attacks in multiple dimensions. Most organizations perform risk management to manage their information security. Generally, they use the information system risk assessment (ISRA). However, the method has difficulties supporting sufficiently analyzing security risks and actively responding to these attacks due to the limitations of asset-driven qualitative evaluation activities. In this paper, we propose a threat-driven risk assessment method. This method can evaluate how dangerous APT attacks are for an organization, analyze security risks from multiple perspectives, and support establishing an adaptive security strategy.

Currently, many organizations are moving to new digital management systems, which is accompanied not only by the introduction of new approaches based on the use of information technology, but also by a change in the organizational and management environment. Risk management is a process necessary to maintain the competitive advantage of an organization, but it can also become involved in the course of digitalization itself, which means that risk management also needs to change to meet modern conditions and ensure the effectiveness of the organization. This article discusses the risk management process in the digital environment. The main approach to the organization of this process is outlined, taking into account the use of information tools, together with the stages of this process, which directly affect the efficiency of the company. The risks that are specific to a digital organization are taken into account. Modern requirements for risk management for organizations are studied, ways of their implementation are outlined. The result is a risk management process that functions in a digital organization.

Boodai, Razan M., Alessa, Hadeel A., Alanazi, Arwa H..  2022.  An Approach to Address Risk Management Challenges: Focused on IT Governance Framework. 2022 IEEE International Conference on Cyber Security and Resilience (CSR). :184–188.
Information Technology (IT) governance crosses the organization practices, culture, and policy that support IT management in controlling five key functions, which are strategic alignment, performance management, resource management, value delivery, and risk management. The line of sight is extended from the corporate strategy to the risk management, and risk controls are assessed against operational goals. Thus, the risk management model is concerned with ensuring that the corporate risks are sufficiently controlled and managed. Many organizations rely on IT services to facilitate and sustain their operations, which mandate the existence of a risk management model in their IT governance. This paper examines prior research based on IT governance by using a risk management framework. It also proposes a new method for calculating and classifying IT-related risks. Additionally, we assessed our technique with one of the critical IT services that proves the reliability and accuracy of the implemented model.
Stefanova-Stoyanova, Varbinka, Danov, Petko.  2022.  Comparative Analysis of Specialized Standards and Methods on Increasing the Effectiveness and Role of PDCA for Risk Control in Management Systems. 2022 10th International Scientific Conference on Computer Science (COMSCI). :1–4.
This article analyzes Risk management (RM) activities against different ISO standards. The aim is to improve the coordination and interoperability of risk management activities in IT, IT services management, quality management, project management, and information security management. The ISO 31000: 2018 standard was chosen as a structured input for ISO 20000-1: 2018, ISO 21500: 2021, ISO 27000: 2018, ISO 9001: 2015 and ISO Annex SL standards relative to RM. The PDCA cycle has been chosen as one of the main methods for planning, implementing, and improving quality management systems and their processes. For a management system to be more effective, more reliable, and capable of preventing negative results, it must deal with the possible resulting risks.
Ramaj, Xhesika.  2022.  A DevSecOps-enabled Framework for Risk Management of Critical Infrastructures. 2022 IEEE/ACM 44th International Conference on Software Engineering: Companion Proceedings (ICSE-Companion). :242–244.
This paper presents a Ph.D. research plan that focuses on solving the existing problems in risk management of critical infrastructures, by means of a novel DevSecOps-enabled framework. Critical infrastructures are complex physical and cyber-based systems that form the lifeline of a modern society, and their reliable and secure operation is of paramount importance to national security and economic vitality. Therefore, this paper proposes DevSecOps technology for managing risk throughout the entire development life cycle of such systems.
Muhamad Nur, Gunawan, Lusi, Rahmi, Fitroh, Fitroh.  2022.  Security Risk Management Analysis using Failure Mode and Effects Analysis (FMEA) Method and Mitigation Using ISO 27002:2013 for Agency in District Government. 2022 10th International Conference on Cyber and IT Service Management (CITSM). :01–06.
The Personnel Management Information System is managed by the Personnel and Human Resources Development Agency on local government office to provide personnel services. The existence of a system and information technology can help ongoing business processes but can have an impact or risk if the proper mitigation is not carried out. It is known that the problems are damage to databases, servers, and computer equipment due to bad weather, network connections being lost due to power outages, data loss due to not having backup data, and human error. This resulted in PMIS being inaccessible for some time, thus hampering ongoing business processes and causing financial losses. This study aims to identify risks, conduct a risk assessment using the failure mode and effects analysis (FMEA) method, and provide mitigation recommendations based on the ISO/IEC 27002:2013 standard. The analysis results obtained 50 failure modes categorized into five asset categories, and six failure modes have a high level. Then provide mitigation recommendations based on the ISO/IEC 27002:2013 Standard, which has been adapted to the needs of Human Resources Development Agency. Thus, the results of this study are expected to assist and serve as material for local office government's consideration in making improvements and security controls to avoid emerging threats to information assets.
Alimzhanova, Zhanna, Tleubergen, Akzer, Zhunusbayeva, Salamat, Nazarbayev, Dauren.  2022.  Comparative Analysis of Risk Assessment During an Enterprise Information Security Audit. 2022 International Conference on Smart Information Systems and Technologies (SIST). :1—6.

This article discusses a threat and vulnerability analysis model that allows you to fully analyze the requirements related to information security in an organization and document the results of the analysis. The use of this method allows avoiding and preventing unnecessary costs for security measures arising from subjective risk assessment, planning and implementing protection at all stages of the information systems lifecycle, minimizing the time spent by an information security specialist during information system risk assessment procedures by automating this process and reducing the level of errors and professional skills of information security experts. In the initial sections, the common methods of risk analysis and risk assessment software are analyzed and conclusions are drawn based on the results of comparative analysis, calculations are carried out in accordance with the proposed model.

Tabak, Z., Keko, H., Sučić, S..  2022.  Semantic data integration in upgrading hydro power plants cyber security. 2022 45th Jubilee International Convention on Information, Communication and Electronic Technology (MIPRO). :50—54.
In the recent years, we have witnessed quite notable cyber-attacks targeting industrial automation control systems. Upgrading their cyber security is a challenge, not only due to long equipment lifetimes and legacy protocols originally designed to run in air-gapped networks. Even where multiple data sources are available and collection established, data interpretation usable across the different data sources remains a challenge. A modern hydro power plant contains the data sources that range from the classical distributed control systems to newer IoT- based data sources, embedded directly within the plant equipment and deeply integrated in the process. Even abundant collected data does not solve the security problems by itself. The interpretation of data semantics is limited as the data is effectively siloed. In this paper, the relevance of semantic integration of diverse data sources is presented in the context of a hydro power plant. The proposed semantic integration would increase the data interoperability, unlocking the data siloes and thus allowing ingestion of complementary data sources. The principal target of the data interoperability is to support the data-enhanced cyber security in an operational hydro power plant context. Furthermore, the opening of the data siloes would enable additional usage of the existing data sources in a structured semantically enriched form.

Rojas, Aarón Joseph Serrano, Valencia, Erick Fabrizzio Paniura, Armas-Aguirre, Jimmy, Molina, Juan Manuel Madrid.  2022.  Cybersecurity maturity model for the protection and privacy of personal health data. 2022 IEEE 2nd International Conference on Advanced Learning Technologies on Education & Research (ICALTER). :1—4.
This paper proposes a cybersecurity maturity model to assess the capabilities of medical organizations to identify their level of maturity, prioritizing privacy and personal data protection. There are problems such as data breaches, the lack of security measures in health information, and the poor capacity of organizations to handle cybersecurity threats that generate concern in the health sector as they seek to mitigate risks in cyberspace. The proposal, based upon C2M2 (Cybersecurity Capability Maturity Model), incorporates practices and controls which allow organizations to identify security gaps generated through cyberattacks on sensitive health patient data. This model seeks to integrate the best practices related to privacy and protection of personal data in the Peruvian legal framework through the Administrative Directive No. 294-MINSA and the personal data protection Act No. 29733. The model consists of 3 evaluation phases. 1. Assessment planning; 2. Execution of the evaluation; 3. Implementation of improvements. The model was validated and tested in a public sector medical organization in Lima, Peru. The preliminary results showed that the organization is at Level 1 with 14% of compliance with established controls, 34% in risk, threat and vulnerability management practices and 19% in supply chain management. These the 3 highest percentages of the 10 evaluated domains.
