The Coast Guard anticipates the costs for this final rule to come primarily from several requirements.  These include developing a Cybersecurity Plan and performing cybersecurity drills and exercises.  Additional costs are imposed from ensuring and implementing cybersecurity measures, such as account security measures, device security measures, data security measures, cybersecurity training for personnel, reporting cyber incidents, risk management, penetration testing, supply chain management, resilience, network segmentation, and physical security.  The Coast Guard anticipates non-quantified benefits from reducing the risk of cyber incidents through enhanced detection and correction of vulnerabilities in Information technology (IT) and Operational technology (OT) systems; improved mitigation for impacted entities and downstream economic participants if an incident occurs; and improved protection of Marine Transportation System (MTS) firm and customer data to protect business operations, build consumer trust, and promote increased commerce in the U.S. economy.  Additional benefits will accrue due to improving the minimum standard for cybersecurity to protect the MTS and avoid supply chain disruptions, which is vital to the U.S. economy and U.S. national security.
