Which of the following is a key component of cybersecurity in marine operations?

Conducting vulnerability assessments of navigation systems is a critical component of cybersecurity in marine operations because these systems are essential for the safe and efficient navigation of vessels. Vulnerability assessments involve identifying, quantifying, and prioritizing the vulnerabilities present in the navigation systems, which can be targets for cyber threats. By systematically evaluating these systems, marine operators can detect weaknesses that could be exploited by cyber attackers, enabling them to implement appropriate security measures to mitigate risks.

Protecting navigation systems is paramount, as they are integral to not only the vessel's journey but also the safety of crew and cargo. Ensuring these systems are resilient against cyber threats enhances overall maritime safety and operational integrity, which aligns with broad cybersecurity objectives.

In contrast, while managing crew schedules, increasing personnel numbers, or limiting communications may have their own importance in operational efficiency and safety, they do not directly address the vulnerabilities of critical systems that could be exploited in cyber-attacks. These options focus more on logistics and communication rather than on strengthening the cybersecurity posture of operations.
