Name a key regulation influencing maritime cybersecurity practices.

The International Ship and Port Facility Security (ISPS) Code is a key regulation influencing maritime cybersecurity practices because it was developed specifically to enhance the security of ships and port facilities. Established by the International Maritime Organization (IMO) following the events of September 11, 2001, the ISPS Code sets out a comprehensive framework for protecting maritime operations from various threats, including cyber threats.

The ISPS Code requires member states to assess risks and develop security plans that encompass not just physical security of vessels and ports but also the Information Technology systems that support maritime operations. This regulatory framework emphasizes the importance of risk assessment, security measures, and the training of personnel, thus integrating cybersecurity into the broader security landscape of maritime operations.

In contrast, other options may address aspects of maritime law or operational safety but do not focus specifically on both maritime security and the implications for cybersecurity like the ISPS Code does.
