A new cybersecurity regulation from the U.S. Coast Guard is now in force, according to a report by Kelly Malynn. The Cybersecurity in the Marine Transportation System regulation, which went into effect in July 2025, updates maritime security regulations to address accelerating cyber risks.The rule establishes minimum cybersecurity and reporting requirements for U.S.-flagged vessels, Outer Continental Shelf facilities, and facilities subject to the Maritime Transportation Security Act of 2002. It is one of the first regulations to specifically reference vessel security and includes notification requirements for formal tracking of incidents.Owners and operators must now develop and maintain a cybersecurity plan and a cyber incident response plan. These plans must include specific account, device, and data security measures. Required measures include enabling automatic account lockout after repeated failed login attempts, maintaining a list of approved hardware and software, and securely capturing and storing logs for privileged users only.A designated staff member must serve as Cybersecurity Officer. This officer is responsible for facilitating the cybersecurity plans, arranging inspections and annual audits, ensuring training is conducted, and reporting any cybersecurity incidents that impact the vessel.Reportable incidents are defined as anything that disrupts or threatens the safety of a vessel or an organization’s operations and must be reported to the National Response Center without delay. The regulation integrates cyber preparedness into core maritime operations, requiring staff to incorporate cyber drills into safety structures, similar to fire or man-overboard drills.New staff members must receive cybersecurity training within five days of gaining system access, but no later than 30 days after hiring, with annual training required thereafter.The report suggests maritime organizations consider several key questions regarding their cybersecurity posture. These include identifying third-party contacts for incidents at sea, confirming the designated Cybersecurity Officer, planning support for ship owners and crews, ensuring forensic investigation training, and establishing procedures for resolving incidents involving compromised technology.Having third-party vendors prepared in advance is highlighted as crucial for swift response, system restoration, and forensic investigations. The report also notes that marine and cyber insurance providers can offer support in managing cyber risk by sharing insights from past claims and providing expert guidance. Insurance products vary, with some offering affirmative cover and others addressing cyber exclusions in traditional cargo policies.The regulation represents a shift in how maritime cyber safety is defined, requiring the development of resilient systems, consistent training and reporting, and insurance coverage that keeps pace with changing risks.
