What is a recommended practice when dealing with sensitive data on marine vessels?

Using encryption for stored and transmitted data is a recommended practice when dealing with sensitive data on marine vessels because it ensures that even if data is intercepted or accessed without authorization, it remains unreadable without the correct encryption key. Encryption protects sensitive information from being exposed to unauthorized individuals, thus safeguarding the privacy and integrity of the data. This practice is particularly vital in maritime environments where data can be vulnerable due to various cybersecurity threats and where information may be transmitted over potentially insecure networks.

Moreover, encrypting data contributes to compliance with various regulations and standards regarding data protection, which is crucial in maintaining legal responsibilities and avoiding potential penalties. It also fosters trust among crew members and stakeholders by demonstrating a commitment to safeguarding sensitive information.

In contrast, storing data on unsecured devices poses significant risks as these devices can be easily compromised. Sharing passwords freely undermines accountability and can lead to unauthorized access. Limiting access based solely on crew seniority may not effectively address the need for cybersecurity, as it does not consider the specific relevance and need for access to sensitive information across different roles on the vessel.
