Topics on maritime cyber security have undoubtedly been attracting great public attention in recent days. The reasons are rapidly evolving computing technologies and digitalization in maritime sector. A successful cyber-attack may have catastrophic consequences and a harmful impact on people, properties or marine environment. In addition to numerous factors that pave the way for a successful cyber-attack on ships, human errors are also in the limelight as they are notorious sources of cyber-attacks today. In this research paper, the authors examine Montenegrin seafarers’ level of familiarisation with current cyber-security risks by conducting a structured survey questionnaire. After thoroughly analysing the collected answers, the authors realise that the respondents have an insufficient level of cyber-security knowledge and awareness. Lastly, using the quantitative risk assessment method, the authors propose the best practices for maritime cyber security in the form of implementation of mandatory training course.

<p>This paper presents a risk assessment method for assessing the cyber security of power systems in view of the role of protection systems. This paper examines the collision of transmission and bus line protection systems positioned in substations on the cyber-physical performance of the power systems. The projected method simulates the physical feedback of power systems to hateful attacks on protection system settings and parameters. The relationship between protection device settings, protection logic, and circuit breaker logic is analyzed. The expected load reduction (ELC) indicator is used in this paper to determine potential losses in the system due to cyber attacks. The Monte Carlo simulation is used to calculate ELC’s account to assess the capabilities of the attackers and bus arrangements are changed. The influence of the projected risk assessment method is illustrated by the use of the 9-bus system and the IEEE-68 bus system.</p>

Types Of Information

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”.

Recommender Algorithm

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.

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.

Bank Robbery

Because banks are very often target of a cyber-attack, they have also good security controls in place. This paper analysis modern threats to banks and proposes an approach to detect and visualize the risk of data leakage. In the first part of this paper, a comparative analysis of the most common threats to the banking sector is made, based on both bank reports and cyber security companies. The authors came to the conclusion that at the bottom line, insider knowledge is necessary, which is the result of data leakage. This paper comparatively analysis modern threats to banks and shows an approach to detect and visualize the risk of data leakage. In the second part of the paper, a model - based on network graph - that can enumerate the risk of data leakage is proposed. Graphing a network of an organization with the connections of data flow between assets and actors can identify insecure connections that may lead to data leakage. As is demonstrated in this paper, financial institutions are important targets of cyber attacks. Consequently, the financial sector must invest heavily in cybersecurity and find the best ways to counter cyber attacks and cyber bank robbery attempts.
