What documentation is necessary for operational deficiencies related to cyber risk?

Documenting operational deficiencies related to cyber risk is crucial for several reasons, including compliance, accountability, and continuous improvement. The correct answer emphasizes the importance of a structured approach through "Form B with specified timelines."

This form likely includes specific guidelines for documenting deficiencies, which helps ensure that issues are not only identified but also addressed systematically. By having specified timelines, it promotes timely responses to identified cyber risks, thereby minimizing potential impacts on operational safety and efficiency. This documentation can be essential for audits, evaluations, and regulatory compliance, making it a critical element in managing cyber security within marine operations.

In contrast, impromptu notes or verbal reports lack the formal structure and accountability necessary for effective risk management and may lead to misunderstandings or omissions. General operational logs can provide some context but do not offer the specificity and action-oriented detail that a designated form would provide.
