<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>

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.
