Abstract:

Organizations expect their employees to connect securely to the organization's computer systems. Often these employees use their personal computers to access the organization's networks. This research explores whether these same employees apply protective security measures to their personal computers. Perhaps these employees behave riskily based on their optimistic bias. Results indicate that while cyber optimistic bias and perceived vulnerability influence individuals to apply more protective security measures, the users still experienced security incidents. Thus, organization are vulnerable to cyber-attacks if they are allowing employees to use personal computers to access these databases.

Abstract:

The work is dedicated to the analysis and improvement of methods and tools for building the architecture of software-defined networks (SDNs). A crucial aspect involves comparing the differences between network management using traditional methods and utilizing an SDN controller. Primary attention is given to the development of security models based on software-defined networks.The research is grounded in the analysis of specific cases involving the use of such networks, including gathering opinions and expert assessments from professionals in the field. It leverages publicly available information on methods and tools for securing the architecture of software-defined networks. SDN technology provides greater flexibility and speed in implementing security measures, allowing real-time responses to threats. In contemporary conditions, where cyber threats are becoming more complex and pronounced, SDN networks enable the detection of attacks, blocking malicious actions, and applying security policies in real-time. However, the increasing complexity of cyber threats and constant technological changes necessitate further development and enhancement of the information security of SDN network resources for companies. There is a need for further analysis and improvement of methods and tools for protecting information and other resources in computer-based SDN networks. The necessity for further analysis and improvement of methods and tools for protecting information and other resources in computer-based SDN networks serves as the foundation for this research. As a result, an enhancement in the level of information security for SDN network resources has been achieved by: 1) reducing the intervention time in the network; 2) applying an improved method of traffic processing based on network security of packet flows, allowing desired network applications to efficiently manage forwarding.

Abstract:

In reality, some computers have specific security classification. For the sake of safety and cost, the security level of computers will be upgraded with increasing of threats in networks. Here we assume that there exists a threshold value which determines when countermeasures should be taken to level up the security of a fraction of computers with low security level. And in some specific realistic environments the propagation network can be regarded as fully interconnected. Inspired by these facts, this paper presents a novel computer virus dynamics model considering the impact brought by security classification in full interconnection network. By using the theory of dynamic stability, the existence of equilibria and stability conditions is analysed and proved. And the above optimal threshold value is given analytically. Then, some numerical experiments are made to justify the model. Besides, some discussions and antivirus measures are given.

Abstract:

The terms “kiberushishroeba” (cyber security) and “kiberusaprtkhoeba” (computer security) are often used in inappropriate contexts. The term “kiberushishroeba” is used when the avoidance of an imminent threat requires the formulation and implementation of socio-political measures (development and adoption of doctrines, laws, legal acts, improvement of the “kiberushishroeba” and “kiberusaprtkhoeba” assurance management process), because the state of protection of national interests in cyberspace is achieved through the establishment of an effective Computer Security system, cyberspace sustainability, protection from unwanted internal and external influences – as a result of qualified cyber policy. The starting-point in “kiberushishroeba” providing is political aim and the result – to achieve them. “Kiberusaprtkhoeba” is an integral component of “kiberushishroeba”, a carrier of different content and weight. “Kiberusaprtkhoeba” is a combination of technologies, methods and processes of technical protection against cyberattacks of components (networks, computers, programs, data, devices) within the field of computer and information-telecommunication. It is more associated with protection from "technical" threats (to be taken organizational-technical measures: to identify those responsible for the operation safety of the computerinformation-telecommunication field and to introduce appropriate technical infrastructure and security system) or rather to “protection of labor safety” than formulation and implementation of socio-political goals. The goal of “kiberusaprtkhoeba” is to protect them, and to achieve this protection as a whole is ensuring of the result that meets the requirements of the political goal of “kiberushishroeba”.

Abstract:

Moving target defense (MTD) strategies have been widely studied for securing computer systems. We consider using MTD strategies to provide long-term cryptographic security for message transmission against an eavesdropping adversary who has access to a quantum computer. In such a setting, today’s widely used cryptographic systems including Diffie-Hellman key agreement protocol and RSA cryptosystem will be insecure and alternative solutions are needed. We will use a physical assumption, existence of multiple communication paths between the sender and the receiver, as the basis of security, and propose a cryptographic system that uses this assumption and an MTD strategy to guarantee efficient long-term information theoretic security even when only a single path is not eavesdropped. Following the approach of Maleki et al., we model the system using a Markov chain, derive its transition probabilities, propose two security measures, and prove results that show how to calculate these measures using transition probabilities. We define two types of attackers that we call risk-taking and risk-averse and compute our proposed measures for the two types of adversaries for a concrete MTD strategy. We will use numerical analysis to study tradeoffs between system parameters, discuss our results, and propose directions for future research.

Abstract:

At present, malware is still a major security threat to computer networks. However, only a fraction of users with some security consciousness take security measures to protect computers on their own initiative, and others who know the current situation through social networks usually follow suit. This phenomenon is referred to as conformity psychology. It is obvious that more users will take countermeasures to prevent computers from being infected if the malware spreads to a certain extent. This paper proposes a deterministic nonlinear SEIQR propagation model to investigate the impact of conformity psychology on malware propagation. Both the local and global stabilities of malware-free equilibrium are proven while the existence and local stability of endemic equilibrium is proven by using the central manifold theory. Additionally, some numerical examples and simulation experiments based on two network datasets are performed to verify the theoretical analysis results. Finally, the sensitivity analysis of system parameters is carried out.

Full text

Abstract:

Wireless sensor networks (WSNs) are networks formed by organizing and combining tens of thousands of sensor nodes freely through wireless communication technology. WSNs are commonly affected by various attacks, such as identity theft, black holes, wormholes, protocol spoofing, etc. As one of the more severe threats, wormholes create passive attacks that are hard to detect and eliminate. Since WSN is often used in the tactical network field, a planned secure network is essential for military applications with high security. Guard nodes are traffic monitoring nodes used to supervise neighbors’ data communication around the tactical networks. Therefore, this work proposes a Quality of Service (QoS) security mechanism to select multiple dual-layer guard nodes at different paths of the WSN based on the path qualities to detect wormholes. The entire network’s links are categorized into high, normal, and low priority levels. As such, this study aimed to confirm the security of high priority nodes and links in the tactical network, avoid excessive overhead, and provide random security facilities to all nodes. The proposed measures of the QoS-based security provision, including link cluster formation, guard node selection, authenticated guard node identification, and intrusion detection, ensure economic and efficient network communication with different quality levels.

Abstract:

Epidemiological dynamics is a vital method in studying the spread of computer network viruses. In this paper, an optimal control measure is proposed based on the SEIR virus propagation model in point-to-group information networks. First, considering the need for antivirus measures in reality, an optimal control problem is introduced, and then a controlled computer virus spread model in point-to-group information networks is established. Second, the optimal control measure is formulated by making a tradeoff between control cost and network loss caused by virus intrusion. Third, optimal control strategies are theoretically investigated by Pontryagin’s maximum principle and the Hamiltonian function. Finally, through numerical simulations, effective measures for controlling virus spread in point-to-group information networks are proposed.

Honeypot technology is essentially a technique of deceiving attackers by deploying hosts, network services, or information as bait to lure them into attacking. This allows for the capture and analysis of attack behavior, speculating on attack intentions and motivations, enabling the defense to have a clear understanding of the security threats they face, and enhancing the security protection capabilities of the actual system through technical and management measures. A honeypot is like an intelligence gathering system. It is also possible to eavesdrop on the connections between hackers, collect various tools used by hackers, and gain control of their social networks.

Abstract:

Securing a safety-critical system is a challenging task, because safety requirements have to be considered alongside security controls. We report on our experience to develop a security architecture for railway signalling systems starting from the bare safety-critical system that requires protection. We use a threat-based approach to determine security risk acceptance criteria and derive security requirements. We discuss the executed process and make suggestions for improvements. Based on the security requirements, we develop a security architecture. The architecture is based on a hardware platform that provides the resources required for safety as well as security applications and is able to run these applications of mixed-criticality (safety-critical applications and other applications run on the same device). To achieve this, we apply the MILS approach, a separation-based high-assurance security architecture to simplify the safety case and security case of our approach. We describe the assurance requirements of the separation kernel subcomponent, which represents the key component of the MILS architecture. We further discuss the security measures of our architecture that are included to protect the safety-critical application from cyberattacks.

Abstract:

Today cybercrime and computer terrorism are identified as one of the threats to Ukraine’s national security in the information sphere. Cybersecurity measures include achieving and maintaining security features in the resources of an institution or users, aimed at preventing relevant cyber threats. Cybercrime is a set of criminal offenses committed in cyberspace by computer systems or by using computer networks and other means of access to cyberspace, within computer systems or networks, as well as against computer systems, computer networks and computer data, has been widely developed. The paper considers such terms as «computer crime», «information crime», «crime in the field of computer information», «crimes in the field of information technology». Scientific works of domestic and foreign researchers on the issues of countering cybercrime are analyzed. The connection of the concept of «cybersecurity» with the terms «cybercrime», «computer crime» and «cybercrime» the concepts of «cybercrime» was given. The difference in the interpretation of the concepts «cybersecurity» and «information security» was considered. The definitions of «cybercrime», «computer crime» and «cyber offense» were given for comparison. Their main features were considered. The concept of «computer victimhood» and its components were considered. With the introduction of the institute of criminal offenses in the national criminal law, the terms «cybercrime» and «computer crime» should lose their relevance, as evidenced by the change of title of Chapter XVI of the Criminal Code of Ukraine to «Criminal offenses in the use of electronic computing machines (computers), systems and computer networks and telecommunications networks». Therefore, instead, we can recommend the use of the term «cyber offense», which we propose to understand as «socially dangerous criminal act in cyberspace and/or using it, liability for which is provided by the law of Ukraine on criminal liability and/or which is recognized as a criminal offense by international treaties of Ukraine, and cybercrime is a set of cyber offences». It is clear that this will require the introduction of appropriate terminological changes in the Law of Ukraine «On the Basic Principles of Cyber Security of Ukraine» and other regulations.

Abstract:

During the 20th century, technological progress rewarded the convergence of telecommunications and computer technology. This marked the beginning of an era known as the information age. The information age is characterized by the growth of digitalization, which mainly performs the technological transition from analog and electromechanical technologies to digital technologies. A very characteristic feature of the information age is the continuous integration of computer and digital communication technologies into virtually every aspect of life. This has led to the emergence of the information society, which has fundamentally changed traditional perceptions of security. The security of digital data, computers, digital communications technologies and information networks now has a predominant impact on all aspects of life and society. Thus, with the advent of the information society, malicious actions against information systems, such as computer systems and networks, can now affect individuals, the country and the global economy in a way that was previously unheard of. Measures to address these information security issues have given rise to a new concept known as «cybersecurity». Cybersecurity of information is aimed at promoting and ensuring the overall security of digital and information systems with the security of the information society. Thus, the concept of a wide range of social, legal, regulatory and technological measures that ensure the integrity, confidentiality, accessibility and overall security of digital information and information systems to achieve the high level of trust and security necessary for the development of a sustainable information society. Advocacy is inextricably linked to confidential information. Providing protection and security of information about one of the best tasks of advocacy. The age of digitization of advocacy is transforming the usual procedural agenda. This creates a new mystery for lawyers. In a profession where trust and confidentiality are as sacred as keeping clients secret, is the amount of information that comes to your attention increasingly beyond your control?

Abstract:

The paper presents an experimental security assessment within two widely used open-source 5G projects, namely Open5GS and OAI (Open-Air Interface). The examination concentrates on two network functions (NFs) that are externally exposed within the core network architecture, i.e., the Access and Mobility Management Function (AMF) and the Network Repository Function/Network Exposure Function (NRF/NEF) of the Service-Based Architecture (SBA). Focusing on the Service-Based Interface (SBI) of these exposed NFs, the analysis not only identifies potential security gaps but also underscores the crucial role of Mobile Network Operators (MNOs) in implementing robust security measures. Furthermore, given the shift towards Network Function Virtualization (NFV), this paper emphasizes the importance of secure development practices to enhance the integrity of 5G network functions. In essence, this paper underscores the significance of scrutinizing security vulnerabilities in open-source 5G projects, particularly within the core network’s SBI and externally exposed NFs. The research outcomes provide valuable insights for MNOs, enabling them to establish effective security measures and promote secure development practices to safeguard the integrity of 5G network functions. Additionally, the empirical investigation aids in identifying potential vulnerabilities in open-source 5G projects, paving the way for future enhancements and standard releases.

Abstract:

The detection of intrusions in computer networks, known as Network-Intrusion-Detection Systems (NIDSs), is a critical field in network security. Researchers have explored various methods to design NIDSs with improved accuracy, prevention measures, and faster anomaly identification. Safeguarding computer systems by quickly identifying external intruders is crucial for seamless business continuity and data protection. Recently, bioinformatics techniques have been adopted in NIDSs’ design, enhancing their capabilities and strengthening network security. Moreover, researchers in computer science have found inspiration in molecular biology’s survival mechanisms. These nature-designed mechanisms offer promising solutions for network security challenges, outperforming traditional techniques and leading to better results. Integrating these nature-inspired approaches not only enriches computer science, but also enhances network security by leveraging the wisdom of nature’s evolution. As a result, we have proposed a novel Amino-acid-encoding mechanism that is bio-inspired, utilizing essential Amino acids to encode network transactions and generate structural properties from Amino acid sequences. This mechanism offers advantages over other methods in the literature by preserving the original data relationships, achieving high accuracy of up to 99%, transforming original features into a fixed number of numerical features using bio-inspired mechanisms, and employing deep machine learning methods to generate a trained model capable of efficiently detecting network attack transactions in real-time.

Abstract:

The security and life time of network are most import factors in wireless sensor networks (WSN). In this research work Mediative Micro ANN Fuzzy logic(MMAFL) has been proposed, along with load-balance routing algorithm. The designed method can increase WSN’s additional feature like securing packet from message capture and tampering attacks. The aim of the proposed routing algorithm is reduce the overall energy consumption and ensure fair use of node energy, so that lifetime of the network has been automatically increased. Experimentation of the proposed Mediative Micro ANN Fuzzy logic is implemented in MATLAB 2018b software and compared with the existing techniques to prove the effectiveness of the approach. The MMAFL model is most useful for medical, Mobile, and industrial applications for data transferring and network security. The performance measures like accuracy 97.45%, F measure 97.34%, overhead 11.10%, delay 8.96ms, throughput 90%, lifetime 27%, and packet-delivery ration 86.11% had been attained, which are most prominent compared to earlier models.

Abstract:

Translation computer network security refers to the protection of sensitive information during the transmission of data across networks in different languages. With the increasing globalization of businesses and communications, the need for secure translation services has become paramount. Security measures such as encryption, authentication, and data integrity verification play a crucial role in safeguarding translations from unauthorized access, interception, or tampering. Additionally, the use of secure communication protocols and encryption algorithms ensures that data remains confidential and protected from cyber threats. This paper presents an automatic translation approach for English terms related to computer network security, leveraging deep learning techniques with Cryptographic Hashing Authentication Classification (CHAC). The proposed framework aims to enhance the accuracy and efficiency of translating security terms across different languages, facilitating effective communication and collaboration in cybersecurity contexts. Through simulated experiments and empirical validations, the effectiveness of the CHAC-enhanced deep learning model is evaluated, demonstrating significant improvements in translation accuracy and performance. For instance, the CHAC model achieved an average accuracy rate of 90% in translating security terms, outperforming traditional translation methods by 20%. Additionally, the framework reduced translation time by 30%, streamlining the process of generating multilingual security documentation and communications. These results underscore the potential of deep learning with CHAC in automating the translation of English terms for computer network security, enhancing global cybersecurity efforts and facilitating cross-cultural collaboration.

Abstract:

Today, most businesses are based on a computer system, more or less developed. For daily activities the organization needs to be able to connect to the Internet, possibly from a local area network (LAN). But, once with the benefits of the Internet, there are also security risks that the organization must minimize by measures and appropriate controls. Among security issues arising from using the Internet include hacker attacks, computers infection with viruses, malware and spyware. In theory, hackers can enter inside the organization network and steal confidential data, damaging computers or the entire organization's local area network. In this sense, firewall implementation is a security measure needed to any organization. This paper presents firewall types and technologies, attacks on firewalls and some security measures on the internal network.
