International community has been traditionally focusing on physical threats to facilities and pass by the threat of a cyber attack on a facility. All the same, due to the growing threat posed by cyber attacks; cyber security is becoming indispensable component of nuclear facilities and it is setting up itself as a main concern for facility operators and national regulators. Consequently, ensuring the security of nuclear facilities is a considerable element, which gears at avoiding theft of nuclear materials and sabotage. For that reason, this paper was set to examine impact of cyber threats to nuclear facility. Specifically, the paper has examined cyber threats, cyber threats to nuclear facility, impact of cyber threats to nuclear facility. It is concluded that cyber threat to nuclear facility is growing despite numerous effort taken to offset the problem. Thus, there is a need either to design or improve available cyber threat mitigation procedure in order to tone down the problem.

We are facing the expansion of cyber incidents, and they are becoming more severe. This results in the necessity to improve security, especially in the vulnerable field of critical infrastructure. One of the problems in the security of critical infrastructures is the level of awareness related to the effect of cyberattacks. The threat to critical infrastructure is real, so it is necessary to be aware of it and anticipate, predict, and prepare against a cyber attack. The main reason for the escalation of cyberattacks in the field of Critical Infrastructure (CI) may be that most control systems used for CI do not utilise propriety protocols and software anymore; they instead utilise standard solutions. As a result, critical infrastructure systems are more than ever before becoming vulnerable and exposed to cyber threats. It is important to get an insight into what attack types occur, as this may help direct cyber security efforts. In this chapter, the authors present vulnerabilities of SCADA systems against cyber attack, analyse and classify existing cyber attacks, and give future directions to achieve better security of SCADA systems.

States, organizations and individuals are becoming targets of both individual and state-sponsored cyber-attacks, by those who recognize the impact of disrupting security systems and effect to people and governments. The energy sector is seen as one of the main targets of cyber-attacks against critical infrastructure, but transport, public sector services, telecommunications and critical (manufacturing) industries are also very vulnerable. One of most used example of cyber-attack is the Ukraine power grid attack in 2015 that left 230,000 people without power for up to 6 hours. Another most high profile example of a cyber-attack against critical infrastructure is the Stuxnet computer virus (first used on Iranian nuclear facility) which could be adapted to attack the SCADA systems (industrial control systems) used by many critical infrastructures in Europe.Wide range of critical infrastructure sectors are reliant on industrial control systems for monitoring processes and controlling physical devices (sensors, pumps, etc.) and for that reason, physical connected devices that support industrial processes are becoming more vulnerable. Not all critical infrastructure operators in all sectors are adequately prepared to manage protection (and raise resilience) effectively across both cyber and physical environments. Additionally there are few challenges in implementation of protection measures, such as lack of collaboration between private and public sector and low levels of awareness on existence of national key legislation.From supranational aspect, in relation to this papers topic, the European Union has took first step in defense to cyber threats in 2016 with „Directive on security of network and information systems“ (NIS Directive) by prescribing member states to adopt more rigid cyber-security standards. The aim of directive is to improve the deterrent and increase the EU’s defenses and reactions to cyber attacks by expanding the cyber security capacity, increasing collaboration at an EU level and introducing measures to prevent risk and handle cyber incidents. There are lot of other „supporting tools“ for Member States countries, such as European Union Agency for Network and Information Security – ENISA (which organize regular cyber security exercises at an EU level, including a large and comprehensive exercise every two years, raising preparedness of EU states); Network of National Coordination Centers and the European Cybersecurity Industrial, Technology and Research Competence Centre; and Coordinated response to major cyber security incidents and crises (Blueprint) with aim to ensure a rapid and coordinated response to large-scale cyber attacks by setting out suitable processes within the EU.Yet, not all Member States share the same capacities for achieving the highest level of cyber-security. They need to continuously work on enhancing the capability of defense against cyber threats as increased risk to state institutions information and communication systems but also the critical infrastructure objects. In Southeast Europe there are few additional challenges – some countries even don't have designated critical infrastructures (lower level of protection; lack of „clear vision“ of criticality) and critical infrastructures are only perceived through physical prism; non-EU countries are not obligated to follow requirements of European Union and its legislation, and there are interdependencies and transboundary cross-sector effects that needs to be taken in consideration. Critical infrastructure Protection (CIP) is the primary area of action, and for some of SEE countries (like the Republic of Croatia) the implementation of cyber security provisions just complements comprehensive activities which are focused on physical protection.This paper will analyze few segments of how SEE countries cope with new security challenges and on which level are they prepared for cyber-attacks and threats: 1. Which security mechanisms they use; 2. The existing legislation (Acts, Strategies, Plan of Action, etc.) related to cyber threats in correlation with strategic critical infrastructure protection documents. Analysis will have two perspectives: from EU member states and from non-EU member states point of view. Additionally, for EU member states it will be analyzed if there were any cyber security legislation before NIS directive that meets same aims. The aim of research is to have an overall picture of efforts in region regarding cyber-security as possibility for improvement thorough cooperation, organizational measures, etc. providing also some recommendations to reduce the gap in the level of cyber-security development with other regions of EU.

Every day organizations are targeted by different and sophisticated cyber attacks. Most of these organizations are unaware that they are targeted and their networks are compromised. To detect the compromised networks the organizations need a reliable source of cyber threats information.  Many cyber security service vendors provide threat intelligence information to allow early detection of the cyber threats. This research will explore different type of cyber threat intelligence and its role in proactive incident response. The research study the threat intelligence features and how the threat feeds collected and then distributed.  The research studies the role of cyber threat intelligence in early detection of the threats.

As technology continues to develop, information and communication technology and operational technology on board ships are increasingly being networked, and more frequently connected to the Internet. The introduction of cyber systems changes the work environment with the aim of decreasing the workload for the navigator, but at the same time introduces more complexity and vulnerabilities that in turn may alter the competencies needed to perform safe and efficient navigation. Contemporary examples of how cyber-attacks can distort situational awareness and interfere with operations are needed to enhance the navigator's competence through increased system awareness. This paper demonstrates some of the possible attack vectors that a cyber-attack can present to a ship, as well as discussing the plausibility and consequences of such attacks. In this study we provide a practical example to better understand how one can demystify cyber threats in order to enhance the navigators' competence.

Small and Medium Businesses (SMB) use Internet and computer-based tools in their daily processes, sometimes without being aware to the cyber threats, or without knowing how to be prepared in case of a cyber-attack, although they are a major target for cyber-attacks. Specific information about cybersecurity needed by SMBs, in order to cope with cyber threats, is not always available or easily accessible. In this study, a vast search of different types of information about SMBs’ cybersecurity was performed, in order to find whether a hole of accessible information exists in this area. This exploratory research covered general mass communication media channels, technological and professional cybersecurity websites, and academic journals, and found that indeed very few studies, articles and news items were published in this matter. Leveraging knowledge and awareness, diminishing the shame for reporting cyber-attacks, and increasing mass communication media interest and public attention, may be activities to cover this “invisible hole”.

In the domain of cyber security, the defence mechanisms of networks has traditionally been placed in a reactionary role. Cyber security professionals are therefore disadvantaged in a cyber-attack situation due to the fact that it is vital that they maneuver such attacks before the network is totally compromised. In this paper, we utilize the Betweenness Centrality network measure (social property) to discover possible cyber-attack paths and then employ computation of similar personality of nodes/users to generate predictions about possible attacks within the network. Our method proposes a social recommender algorithm called socially-aware recommendation of cyber-attack paths (SARCP), as an attack predictor in the cyber security defence domain. In a social network, SARCP exploits and delivers all possible paths which can result in cyber-attacks. Using a real-world dataset and relevant evaluation metrics, experimental results in the paper show that our proposed method is favorable and effective.

<div>Cyber-worthiness as it is termed in Australian Defence, or cyber-maturity more broadly, is a necessary feature of modern complex systems which are required to operate in a hostile cyber environment. To evaluate the cyber-worthiness of complex systems, an assessment methodology is required to examine a complex system’s or system-of-system’s vulnerability to and risk of cyber-attacks that can compromise such systems. This assessment methodology should address the cyber-attack surface and threat kill chains, including supply chains and supporting infrastructure. A cyber-worthiness capability assessment methodology has been developed based on model-based systems engineering concepts to analyse the cyber-worthiness of complex systems and present a risk assessment of various cyber threats to the complex system. This methodology incorporates modelling and simulation methods that provide organisations greater visibility and consistency across diverse systems, especially to drive cybersecurity controls, investment and operational decisions involving aggregated systems. In this paper, the developed methodology will be presented in detail and hypothesised outcomes will be discussed.</div>
