Dependability analysis of cyber security in All-Electric Ships

摘要

The Internet of Things frameworks can improve quality and performance of controlled system but also leading the system to be weaker from the cyber security point of view: new devices can be used to exploit system vulnerabilities with malicious intentions. In this paper the effect of a cyber-attack in a modern all-electric ship Integrated Power System is investigated and an alternative paradigm is exploited with a view to enhancing the system security and reliability. The need for security by design has become crucial but it is not enough to prevent all the cyber-attacks and so the dependability theory approach is considered in order to avoid the undesired system failures.
