Rules of the Cape Town Convention on International Interests in Mobile Equipment and Fundamental Principles of Private Law: pro et contra .

Registration of an international interest under the rules of the Cape Town Convention is aimed at establishing priority for such an interest in relation to all third parties, but it does not constitute the basis for the occurrence of the corresponding security obligation. The purpose of registering an international interest is to notify third parties of title or encumbrance. The debtor is a party to the relevant security agreement. If the creditor does not register his security interest (guarantee), the debtor cannot deny its existence or act without taking into account the creditor’s rights under such a guarantee. Competition on the priority of security rights in relation to the same property cannot arise between the debtor and the creditor. The debtor cannot deny that the creditor has rights under the security agreement. The study states that the rules of the Cape Town Convention on priorities are not subject to unconditional application. When considering a dispute over security rights to property, the court should be guided not only by the provisions of the Cape Town Convention on Priorities, but also by the fundamental principles and norms of national law (applicable law). Fundamental principles of civil law cannot be abrogated by Cape Town Convention rules.

Role of the Regulation Framework in Occupational Safety in Construction Excavation Works—A Survey Analysis in Turkey

The construction sector is known to have the highest risks of occupational accidents. A rationale for this high occurrence of occupational risks can be related to legislative requirements to enforce safe construction practices within this sector. Within the context of excavation works in Turkey, this study investigates the leading risks for any compliance shortfalls and ultimately presents recommendations to mitigate occupational accidents’ occurrences during excavation works in the construction sector. Based on a quantitative methodology, a closed-ended survey consisting of 35 questions and based on legislative requirements was applied to project managers in the construction industry, such as site supervisors, occupational safety experts, auditors, and control personnel. A sample size of 277 responses was found to have stability and validity through a reliability analysis and an exploratory factor analysis, and was used for testing statistical significance via cross-tabulation analysis and chi-square tests. The findings revealed that the major deviation of safety in excavation works from legislative requirements is executing works during adverse weather conditions. Moreover, it was also noteworthy that protective curtains did not surround the excavation sites, and most of the employees encountered ground slippage during excavation work. Therefore, the findings revealed preliminary research that will contribute positively to providing incentives for a focus on and development of relevant security and technical measures. It also provided information to protect the safety and welfare of the workers involved in excavation works. Finally, though these findings may be considered context-specific, this research can be used for comparative purposes for similar studies into the safety practices of excavation works in different countries, where generalized findings can be later derived to inform academia and practice.

Some issues of improving the activities of the National Police of Ukraine and local self-government bodies regarding law enforcement at the local level under martial law

The publication highlights the issues of improving the organisation of the work of community police officers and district police inspectors in preventing and combating crime in the territory of service. The importance of implementing security audits of territories and buildings into the activities of community police officers and district police inspectors is proved. Security audits are the main tool that community police officers or district police inspectors can use to identify local security problems specific to a particular area or facilities, identify ways to address relevant risks and threats, and engage all stakeholders in working together to improve their own and others’ safety. The essence of the concept of “Crime Prevention through Environmental Design (CPTED)” and its impact on the formation of a proper state of the security environment at the local level of the community is revealed. It is emphasised that the CPTED principles are universal and can be applied to improve the security of any territory or facility. At the same time, their effectiveness largely depends on the completeness of the identification of security risks and threats. The article suggests the following areas for improvement of the regulatory and legal support for the activities of community police officers: 1) adoption of a separate regulatory legal act on the activities of district police officers, taking into account the peculiarities of police work in the city; 2) approval of instructions on the procedure for carrying out control and supervision activities in the service area. This regulatory act should provide for the forms of such files, the procedure for their completion, registration, verification and control; 3) inclusion of individual cases on security audits of the territory or individual buildings or facilities in the official records of a community police officer. Relevant security audit forms should be officially approved; 4) adoption of methodological recommendations for organising security audits and applying the principles of CPTED (Crime Prevention through Environmental Design) in professional activities.

Toward the European Health Data Space: The IMPaCT-Data secure infrastructure for EHR-based precision medicine research

Background:Art. 50 of the proposal for a Regulation on the European Health Data Space (EHDS) states that “health data access bodies shall provide access to electronic health data only through a secure processing environment, with technical and organizational measures and security and interoperability requirements”. Objective:To identify specific security measures that nodes participating in health data spaces shall implement based on the results of the IMPaCT-Data project, whose goal is to facilitate the exchange of electronic health records (EHR) between public entities based in Spain and the secondary use of this information for precision medicine research in compliance with the General Data Protection Regulation (GDPR). Data and methods:This article presents an analysis of 24 out of a list of 72 security measures identified in the Spanish National Security Scheme (ENS) and adopted by members of the federated data infrastructure developed during the IMPaCT-Data project. Results:The IMPaCT-Data case helps clarify roles and responsibilities of entities willing to participate in the EHDS by reconciling technical system notions with the legal terminology. Most relevant security measures for Data Space Gatekeepers, Enablers and Prosumers are identified and explained. Conclusion:The EHDS can only be viable as long as the fiduciary duty of care of public health authorities is preserved; this implies that the secondary use of personal data shall contribute to the public interest and/or to protect the vital interests of the data subjects. This condition can only be met if all nodes participating in a health data space adopt the appropriate organizational and technical security measures necessary to fulfill their role.

End to End secure data exchange in value chains with dynamic policy updates

Data exchange among value chain partners offers a competitive advantage, but it also exposes sensitive data to increasing risks of compromise. To protect this data, securing it during storage and transmission is essential, allowing only the data producer and final consumer to access or modify it. This can be particularly challenging for Industrial Internet of Things (IIoT) devices, which often have limited processing and memory capabilities. To address these challenges, End-to-End (E2E) security mechanisms are needed to prevent data breaches resulting from value chain attacks. Additionally, value chain environments are dynamic and involve multiple data generation and consumption entities, requiring the ability to update access policies as needed. This paper presents a Ciphertext-Policy Attribute-Based Encryption (CP-ABE) data exchange system that provides E2E security for value chains, considering the most relevant security and industrial requirements. The proposed solution can protect data according to access policies while also allowing those policies to be updated without breaking E2E security or overloading field devices. The experimental evaluation demonstrates the feasibility of the proposed solution for IIoT platforms.

Decision and Complexity of Dolev-Yao Hyperproperties

The formal analysis of cryptographic protocols traditionally focuses on trace and equivalence properties, for which decision procedures in the symbolic (or Dolev-Yao, or DY) model are known. However, many relevant security properties are expressed as DY hyperproperties that involve quantifications over both execution paths and attacker computations (which are constrained by the attacker's knowledge in the underlying model of computation). DY hyperproperties generalise hyperproperties, for which many decision procedures exist, to the setting of DY models. Unfortunately, the subtle interactions between both forms of quantifications have been an obstacle to lifting decision procedures from hyperproperties to DY hyperproperties. The central contribution of the paper is the first procedure for deciding DY hyperproperties, in the usual setting where the number of protocol sessions is bounded and where the equational theory modelling cryptography is subterm-convergent. We prove that our decision procedure can decide the validity of any hyperproperty in which quantifications over messages are guarded and quantifications over attacker computations are limited to expressing the attacker's knowledge. We also establish the complexity of the decision problem for several important fragments of the hyperlogic. Further, we illustrate the techniques and scope of our contributions through examples of related hyperproperties.

A Product-Line-Engineering Framework for Secure Enterprise-Resource-Planning Systems

Enterprise-resource-planning (ERP) systems are highly complex, incorporating critical data and configuration options that can easily cause security threats or risks. While product-line engineering (PLE) provides methods for dealing with configurability, security concerns are not of primary concern in established PLE frameworks. In this paper, we extend the perspectives of established PLE frameworks to incorporate security engineering for ERP systems. We build on a literature review of 15 years (2008-2022) of research on security engineering for ERP systems or product lines. Our framework incorporates three perspectives (i.e., application, security, and domain engineering) with 16 processes and 24 activities. We discuss our framework with respect to the ERP reference architecture and relevant security concerns. Our contributions are intended to help researchers and practitioners obtain a reference on how security engineering can be integrated into PLE for ERP systems.

Problems of the procedural status of property temporarily seized during a search

Introduction. In the aspect of both legislative regulation and practical implementation of such a means of security as temporary seizure of property, it is possible to state a violation of certain fundamental principles - legal certainty, protection against arbitrariness, and observance of human rights. This issue is monitored in terms of the unregulated procedural status of temporarily seized property and insufficient regulation of the legal basis for obtaining such property, that is, the lack of "legitimization" of the corresponding seizure by a special entity. The purpose of the paper is to analyze the essential issues of the legal status of temporarily confiscated property according to the current criminal procedural legislation, the consequences of leveling such a procedural concept, as well as to investigate the guarantees of the rights of the person whose property is confiscated and to identify possible means of overcoming the relevant regulatory gaps. Results. It is noted that a number of problematic issues arise during the application of the relevant security measure, which may at least lead to a violation of the inviolability of a person's property rights. The fundamental and essential basic principles on which the improvement of the institute of temporarily seized property should be based are characterized. In particular, conventional, national and branch principles. Analyzed decisions of the ECtHR. It was established that the things obtained as a result of the search and not specified in the decision of the investigating judge, were left with a procedural status due to the lack of a legal basis, namely a court decision for their receipt. This situation persists with the relevant property until the investigator, the prosecutor submits a petition for seizure of the relevant temporarily seized property to the investigating judge. It is noted that the property of a person, which is important in the context of criminal proceedings, from the time of its acquisition by authorized subjects during the search, until the decision on the seizure of temporarily seized property is made, is in a "procedural vacuum status". Procedural guarantees of the rights of a person whose property is temporarily seized have been analyzed. Conclusions. The author notes the need for further improvement of the institute of temporarily seized property.

The Proposed Framework for Cloud Computing System Security and Privacy Services

Public cloud computing has emerged as a popular and efficient solution for organizations to store, process, and access their data and applications. However, with the increasing adoption of public cloud services, concerns regarding security have become a critical factor in decision-making processes. This study aims to investigate the security aspects of public cloud computing and identify potential vulnerabilities and threats that organizations may face. The aim of this study is to examine the challenges associated with cloud computing and its security concerns. Cloud computing is a technology that utilizes the internet to share data and resources. It is characterized by five key features: On-Demand self-service, Resource Pooling, Broad network access, Rapid elasticity, and Measured Service. However, despite these benefits, cloud computing has several open issues, including Security, Availability, Scalability, and Interoperability. Traditional security techniques are insufficient in fully securing cloud computing. Security and privacy issues often arise during cloud deployment and delivery models. As a result, researchers are interested in learning more about cloud computing security and its methods. Industries are creating architectural models with a high level of protection for their data center to solve current security challenges. This article examines the security of cloud deployment strategies and analyzes cloud security and privacy challenges. The cloud computing service models are also discussed, along with any security issues. The study emphasizes the significance of Audit as a key factor in offering a security solution that covers all relevant security characteristics as determined by the literature. The study's conclusions present a fresh challenge to cloud service providers and suggest a new security paradigm that explains customer security needs. Overall, this study offers a parameter-by-parameter assessment of available security solutions and makes recommendations for enhancements to address cloud security issues.

Robust Localization for Secure Navigation of UAV Formations Under GNSS Spoofing Attack

Nowadays, aerial formations are frequently employed in outdoor scenarios to cooperatively explore and monitor wide areas of interest. In these applications, the vehicles are often exposed to relevant security vulnerabilities, as, for instance, the alteration of navigation signals from an attacker with map counterfeiting (if not even hijacking) purposes. In this work, we focus on an Unmanned Aerial Vehicle (UAV) formation that monitors an area, wherein navigation spoofing attacks may occur. Letting the UAVs cooperate and exploiting the redundancy in the available sensing information, a distributed procedure is proposed to <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$i)$</tex-math> </inline-formula> detect spoofing attacks, and <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$ii)$</tex-math> </inline-formula> support the navigation in adverse conditions. The validity of the designed approach is confirmed by numerical results. Aerial vehicles for outdoor operation are generally endowed with inertial measurements, relative ranging, and GNSS sensing capability. In this work, two cascaded estimation algorithms for concurrent GNSS spoofing detection and localization in a multi-UAV scenario is proposed, to attain robust navigation in areas subject to GNSS spoofing attacks. The attack detection leverages on information theoretic tools to provide a practical threshold test by checking the multimodal measurement consistency. The localization procedures exploit a decision logic relying on measurement reliability to combine information sources that are different in nature, for UAV self-localization in both safe and under-attack conditions. <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Note to Practitioners</i> —Aerial vehicles for outdoor operation are generally endowed with inertial measurements, relative ranging, and GNSS sensing capability.

Efficient and Generic Algorithms for Quantitative Attack Tree Analysis

Numerous analysis methods for quantitative attack tree analysis have been proposed. These algorithms compute relevant security metrics, i.e. performance indicators that quantify how good the security of a system is; typical metrics being the most likely attack, the cheapest, or the most damaging one. However, existing methods are only geared towards specific metrics or do not work on general attack trees. This paper classifies attack trees in two dimensions: proper trees vs. directed acyclic graphs (i.e. with shared subtrees); and static vs. dynamic gates. For three out of these four classes, we propose novel algorithms that work over a generic attribute domain, encompassing a large number of concrete security metrics defined on the attack tree semantics; dynamic attack trees with directed acyclic graph structure are left as an open problem. We also analyse the computational complexity of our methods.

Social Media Zero-Day Attack Detection Using TensorFlow

In the current information era, knowledge can pose risks in the online realm. It is imperative to proactively recognize potential threats, as unforeseen dangers cannot be eliminated entirely. Often, malware exploits and other emerging hazards are only identified after they have occurred. These types of risks are referred to as zero-day attacks since no pre-existing anti-malware measures are available to mitigate them. Consequently, significant damages occur when vulnerabilities in systems are exploited. The effectiveness of security systems, such as IPS and IDS, relies heavily on the prompt and efficient response to emerging threats. Failure to address these issues promptly hinders the effectiveness of security system developers. The purpose of this study is to analyze data from the Twitter platform and deploy machine learning techniques, such as word categorization, to identify vulnerabilities and counteract zero-day attacks swiftly. TensorFlow was utilized to handle the processing and conversion of raw Twitter data, resulting in significant efficiency improvements. Moreover, we integrated the Natural Language Toolkit (NLTK) tool to extract targeted words in various languages. Our results indicate that we have achieved an 80% success rate in detecting zero-day attacks by using our tool. By utilizing publicly available information shared by individuals, relevant security providers can be promptly informed. This approach enables companies to patch vulnerabilities more quickly.

Strategic Entrepreneurship Under the Chaos Theory

Theoretical framework: The research concentrates on 3 main points, which are: (I) The Chaos Theory, (II) Strategic Entrepreneurship, (III) The applied side of the research. It tries to analyze the relationship between these variables by reviewing the introduction, which includes the research problem and hypotheses, as well as reviewing the results and discussions that prove the hypotheses. Methods: Put questions and goals derived from it, to define its hypothetical model with two main hypotheses The research community was (144), while the research sample was (133) from the leaders of the National Security Advisory (Deputy National Security Adviser, general managers, assistant directors general, consultants, department directors, and division directors), to distribute to them (the questionnaire) that was designed by relying on the survey data were analyzed after adopting the descriptive, exploratory approach, on the two statistical packages (SPSS V.28 &amp; AMOS V.25), so that the analysis of its data concludes with identifying the most prominent result of the National Security Advisory’s tendency to improve its Entrepreneurship. Stimulating entrepreneurship and innovation should be part of regulatory agendas that tend to encourage and drive the adoption and dissemination of technologies (Matheus Eurico Soares de Noronha and Et. al., 2023: 26). As it is at the top of the hierarchy in security decision-making and organization before voting on it in the National Security Council headed by the Prime Minister and whose membership constitutes the relevant security and sovereign ministries within the structure of the Iraqi government. One of the reasons for adopting the title of the research was to come up with a clear scientific analytical vision about what the intellectual presentation of chaos theory provides, and the intellectual contributions in the field of strategic Entrepreneurship for the leaders of the National Security Advisers, as well as knowledge integration in bridging potential chaos gaps from the perspective of culture, Entrepreneurship capabilities, and wisdom in disposing of resources and according to priorities. And the goals of the organization and the method of applying innovative ideas concerned with proactively developing creative directions, and on this basis, the research problem was formulated with a main question, was the National Security Advisory able to employ chaos theory in improving its strategic Entrepreneurship? Uniqueness: The strategy is based on the adoption of chaos theory in general, and its dimensions of strange attractor/butterfly effect, bifurcation point, feedback, and self-regulation, as well as adopting strategies to improve the dimensions of strategic Entrepreneurship represented by the employment of strange attractor/butterfly effect, bifurcation point and feedback in improving entrepreneurial culture, and adopting those Dimensions as dimensions of chaos theory in improving entrepreneurial Entrepreneurship, to resort to the strange attractor/butterfly effect, self-organization, and bifurcation point to improve the level of strategic resource management, as well as employing the strange attractor/butterfly effect, bifurcation point and feedback in improving its ability to apply innovation to develop creativity.

Assessing the Solid Protocol in Relation to Security and Privacy Obligations

The Solid specification aims to empower data subjects by giving them direct access control over their data across multiple applications. As governments are manifesting their interest in this framework for citizen empowerment and e-government services, security and privacy represent pivotal issues to be addressed. By analysing the relevant legislation, with an emphasis on GDPR and officially approved documents such as codes of conduct and relevant security ISO standards, we formulate the primary security and privacy requirements for such a framework. The legislation places some obligations on pod providers, much like cloud services. However, what is more interesting is that Solid has the potential to support GDPR compliance of Solid apps and data users that connect, via the protocol, to Solid pods containing personal data. A Solid-based healthcare use case is illustrated where identifying such controllers responsible for apps and data users is essential for the system to be deployed. Furthermore, we survey the current Solid protocol specifications regarding how they cover the highlighted requirements, and draw attention to potential gaps between the specifications and requirements. We also point out the contribution of recent academic work presenting novel approaches to increase the security and privacy degree provided by the Solid project. This paper has a twofold contribution to improve user awareness of how Solid can help protect their data and to present possible future research lines on Solid security and privacy enhancements.

Defending against social engineering attacks: A security pattern‐based analysis framework

AbstractSocial engineering attacks are a growing threat to modern complex systems. Increasingly, attackers are exploiting people's "vulnerabilities" to carry out social engineering attacks for malicious purposes. Although such a severe threat has attracted the attention of academia and industry, it is challenging to propose a comprehensive and practical set of countermeasures to protect systems from social engineering attacks due to its interdisciplinary nature. Moreover, the existing social engineering defence research is highly dependent on manual analysis, which is time‐consuming and labour‐intensive and cannot solve practical problems efficiently and pragmatically. This paper proposes a systematic approach to generate countermeasures based on a typical social engineering attack process. Specifically, we systematically ‘attack’ each step of social engineering attacks to prevent, mitigate, or eliminate them, resulting in 62 countermeasures. We have designed a set of social engineering security patterns that encapsulate relevant security knowledge to provide practical assistance in the defence analysis of social engineering attacks. Finally, we present an automatic analysis framework for applying social engineering security patterns. We applied the case study method and performed semi‐structured interviews with nine participants to evaluate our proposal, showing that our approach effectively defended against social engineering attacks.

Relay-Aided Based Physical Layer Security in VLC System With Improved Noise Model

A visible light communication (VLC) system with an improved noise model applied to physical layer security (PLS) is investigated, where secure beamforming signals with superposition coding are used. In the improved model, the output signal follows Gaussian distribution, but its variance is signal-dependent. Two different methods are proposed to obtain lower and upper bounds on the secrecy rate of the strong user for direct transmission. Under some constraints, closed-form expressions of the lower and upper bounds on secrecy rate regions for various (trusted cooperative half-duplex) relaying schemes are derived. Moreover, the scenarios of blockage/outside coverage are included, and the relevant security performances are discussed. Numerical results show that the lower and upper bounds on secrecy rate regions are tight enough, and the cooperative jamming is superior over other relaying schemes.

Cybersecurity Misinformation Detection on Social Media: Case Studies on Phishing Reports and Zoom’s Threat

Prior work has extensively studied misinformation related to news, politics, and health, however, misinformation can also be about technological topics. While less controversial, such misinformation can severely impact companies’ reputations and revenues, and users’ online experiences. Recently, social media has also been increasingly used as a novel source of knowledgebase for extracting timely and relevant security threats, which are fed to the threat intelligence systems for better performance. However, with possible campaigns spreading false security threats, these systems can become vulnerable to poisoning attacks. In this work, we proposed novel approaches for detecting misinformation about cybersecurity and privacy threats on social media, focusing on two topics with different types of misinformation: phishing websites and Zoom’s security &amp; privacy threats. We developed a framework for detecting inaccurate phishing claims on Twitter. Using this framework, we could label about 9% of URLs and 22% of phishing reports as misinformation. We also proposed another framework for detecting misinformation related to Zoom’s security and privacy threats on multiple platforms. Our classifiers showed great performance with more than 98% accuracy. Employing these classifiers on the posts from Facebook, Instagram, Reddit, and Twitter, we found respectively that about 18%, 3%, 4%, and 3% of posts were misinformation. In addition, we studied the characteristics of misinformation posts, their authors, and their timelines, which helped us identify campaigns.

Securing UAV Flying Base Station for Mobile Networking: A Review

A flying base station based on an unmanned aerial vehicle (UAV) uses its mobility to extend its connectivity coverage and improve its communication channel quality to achieve a greater communication rate and latency performances. While UAV flying base stations have been used in emergency events in 5G networking (sporadic and temporary), their use will significantly increase in 6G networking, as 6G expects reliable connectivity even in rural regions and requires high-performance communication channels and line-of-sight channels for millimeter wave (mmWave) communications. Securing the integrity and availability of the base station operations is critical because of the users’ increasing reliance on the connectivity provided by the base stations, e.g., the mobile user loses connectivity if the base station operation gets disrupted. This paper identifies the security issues and research gaps of flying base stations, focusing on their unique properties, while building on the existing research in wireless communications for stationary ground base stations and embedded control for UAV drones. More specifically, the flying base station’s user-dependent positioning, its battery-constrained power, and the dynamic and distributed operations cause vulnerabilities that are distinct from those in 5G and previous-generation mobile networking with stationary ground base stations. This paper reviews the relevant security research from the perspectives of communications (mobile computing, 5G networking, and distributed computing) and embedded/control systems (UAV vehicular positioning and battery control) and then identifies the security gaps and new issues emerging for flying base stations. Through this review paper, we inform readers of flying base station research, development, and standardization for future mobile and 6G networking.

Digital Workplaces and Information Security Behavior of Business Employees: An Empirical Study of Saudi Arabia

In the post pandemic era, the telecommuting of business employees has widely become acceptable in organizations, which demands extensive dependence on digital technologies. In addition, this poses additional security threats for business employees as well as organizations. In order to better respond to security threats, business employees must have a higher level of awareness of the potential threats that are relevant to digital infrastructure used within the workplace. In this paper, we present a quantitative study conducted in line with the theory of planned behavior to gain insight into employee behavior toward information security within different business sectors in Saudi Arabia. The key factors chosen for our model were password management, infrastructure security management, email management, organizational security policy, organizational support and training, and the perception of the level of security. We have applied structured equation modelling to identify most of the relevant factors based on the respondents’ feedback. The results based on the business employee behavior showed that they respondents did not perceive all of the constructs of our model as relevant security factors, which can potentially result in security lapses. This indicates that more security-related measures should be put in place and that business employees should be updated periodically about potential security threats. To this effect, we divided the studied security measures into those which should be implemented at organizational and individual levels. The results will potentially help business managers to design appropriate security trainings, guidelines, and policies for their employees to ensure more information security awareness and protect their technological infrastructure, especially within home office environments.
