What is considered a best practice for preventing cyber threats in marine safety environments?

Limiting access to network resources is indeed a best practice for preventing cyber threats in marine safety environments because it minimizes the potential attack surface that cybercriminals can exploit. By restricting access, only authorized personnel will have the ability to interact with sensitive systems and data, which greatly reduces the risk of data breaches or unauthorized actions.

In environments where operational continuity is critical, such as in marine safety, it is essential to ensure that only those who need specific resources for their roles can access them. This approach not only enhances security but also aligns with the principle of least privilege, which dictates that users should have the minimum level of access necessary to perform their job functions. This practice actively mitigates the risk of internal threats, where an insider might inadvertently or intentionally compromise security.

On the other hand, completely disconnecting from the internet can severely limit operational efficiency and the timely communication necessary in marine safety operations. Using outdated security software fails to provide adequate protection against evolving cyber threats and vulnerabilities. Similarly, conducting random audits only does not establish a robust framework for continuous monitoring and improvement of security protocols, which is critical in maintaining a resilient posture against cybersecurity threats.
