  • This study aims to build an AHP model that evaluates the priority of cyber security policies for the Azerbaijan information system. For this, 4 factors were constructed from components of ITU National Interest Model, whereas 5 alternatives were based on the best practices of the eight developed countries leading the cyber security field. Using the questionnaire, 24 security experts evaluated the strategic priority of such factors or alternatives. The analysis results using the AHP software showed that homeland defense and economic well-being were the dominant aspects of cyber security policy, whereas capacity building and infrastructure were the main concern of cyber security elements for Azerbaijan. This study presents the strategic priority of cyber security policies that can be adopted by Azerbaijan government. This study can contribute to developing the national cyber security guide of Azerbaijan.

  • With the application of digital technology to safety-critical infrastructures, cyber-attacks have emerged as one of the new dangerous threats. In safety-critical infrastructures such as a nuclear power plant (NPP), a cyber-attack could have serious consequences by initiating dangerous events or rendering important safety systems unavailable. Since a cyber-attack is conducted intentionally, numerous possible cases should be considered for developing a cyber security system, such as the attack paths, methods, and potential target systems. Therefore, prior to developing a risk-informed cyber security strategy, the importance of cyber-attacks and significant critical digital assets (CDAs) should be analyzed. In this work, an importance analysis method for cyber-attacks on an NPP was proposed using the probabilistic safety assessment (PSA) method. To develop an importance analysis framework for cyber-attacks, possible cyber-attacks were identified with failure modes, and a PSA model for cyber-attacks was developed. For case studies, the quantitative evaluations of cyber-attack scenarios were performed using the proposed method. By using quantitative importance of cyber-attacks and identifying significant CDAs that must be defended against cyber-attacks, it is possible to develop an efficient and reliable defense strategy against cyber-attacks on NPPs.

  • This study expands the current body of research by exploring multiple scenarios of insufficient and excessive IT security investments caused by interdependent risks and the interplay between IT security investments and cyber insurance. A key finding is that organizations experiencing interdependent risks with different types of cyber attacks (i.e., targeted and untargeted attacks) use different strategies in making IT security investment decisions and in purchasing cyber insurance policies for their information security risk management than firms that are facing independent risks. The study further provides an economic rationale for employing insurance mechanisms as a risk management solution for information security.

  • Recently, cyber attacks are continuously threatening the cyberspace of the state across the border. Such cyber attacks show a surface which is intelligent and sophisticated level that can paralyze key infrastructure in the country. It can be seen well in cases, such as hacking threat of nuclear power plant, 3.20 cyber terrorism. Especially in public institutions of the country in which there is important information of the country, advanced prevention is important because the large-scale damage is expected to such cyber attacks. Technical support is also important, but by improving the cyber security awareness and security expert knowledge through the cyber security education to the country's public institutions workers is important to raise the security level. This paper suggest education courses for the rise of the best security effect through a short-term course for the country's public institutions workers.

  • In the case of unauthorized individuals, systems and entities or process threatening the instrumentation and control systems of nuclear facilities using the intrinsic vulnerabilities of digital based technologies, those systems may lose their own required functions. The loss of required functions of the critical systems of nuclear facilities may seriously affect the safety of nuclear facilities. Consequently, digital instrumentation and control systems, which perform functions important to safety, should be designed and operated to respond to cyber threats capitalizing on the vulnerabilities of digital based technologies. To make it possible, the developers and licensees of nuclear facilities should perform appropriate cyber security program throughout the whole life cycle of digital instrumentation and control systems. Under the goal of securing the safety of nuclear facilities, this paper presents the KINS' regulatory position on cyber security program to remove the cyber threats that exploit the vulnerabilities of digital instrumentation and control systems and to mitigate the effect of such threats. Presented regulatory position includes establishing the cyber security policy and plan, analyzing and classifying the cyber threats and cyber security assessment of digital instrumentation and control systems.

  • While the term is nothing new, 'cybersecurity' still seems to be defined quite loosely and subjectively depending on context. This is problematic especially to legal writers for prosecuting cybercrimes that do not fit a particular clause/act. In fact, what is more difficult is the non-existent single 'cybersecurity law' in Malaysia, rather than the current implementation of 10-related cyber security acts. In this paper, the 10 acts are compiled into a corpus to analyse the language used in these acts via a corpus linguistics approach. A list of frequent words is firstly investigated to see whether the so-called related laws do talk about cybersecurity followed by close inspection of the concordance lines and habitually associated phrases (clusters) to explore use of these words in context. The 'compare 2 wordlist' feature is used to identify similarities or differences between the 10 Malaysian cybersecurity related laws against a corpus of cyber laws from other ASEAN countries. Findings revealed that ASEAN cyber laws refer mostly to three cybersecurity dominant themes identified in the literature: technological solutions, events, and strategies, processes, and methods, whereas Malaysian cybersecurity-related laws revolved around themes like human engagement, and referent objects (of security). Although these so-called cyber related policies and laws in Malaysia are highlighted in the National Cyber Security Agency (NACSA), their practical applications to combat cybercrimes remain uncertain.

  • As cyber-attacks become more intelligent and sophisticated, the importance of Security Operations Center(SOC) has increased and the number of SOC has been increasing. In order to cope with cyber threats, institutions and organizations use a variety of cyber security standards to create business procedures. However, SOC often need to be improved in accordance with the SOC environment because they collaborate with managed security service specialists rather than their own personnel. The NIST cyber security framework, information security management system, and managed security service companies were compared and analyzed. As a result, it was found that the NIST CSF is a framework that is easy to apply to managed security service, The content was judged to be insufficient. Therefore, in this study, NIST CSF was used as a reference model to derive the management items required for SOC environment, and the necessity, importance and ease of each item were confirmed through an Delphi technique and an improved cyber security framework was proposed.

  • Recently, the Ministry of National Defense has included embedded software for weapon systems as targets for the Defense cyber security. The Concept has been extended and evolved from the cyber security area that was previously limited to the information domain. The software is becoming increasingly important in weapon systems, and it is clear that they are subject to cyber threats. Therefore, We would like to suggest a improvement direction by diagnosing problems in terms of cyber security of the weapon systems for the life cycle. In order to improve cyber security of weapon systems, comprehensive policy including the weapon embedded software management should be established and the involved stakeholder should be participated in the activities.
