Understanding the USCG's New Cybersecurity Rule: What Maritime Operators Need to Know

In January 2025, the U.S. Coast Guard officially released its long-anticipated final rule on cybersecurity within the Marine Transportation System (MTS). This regulation marks a pivotal shift in how maritime operators must approach their cybersecurity posture—not just in terms of compliance, but in their day-to-day operational integrity.

Cybersecurity Requirements Under MTSA

The USCG's final rule requires maritime facilities and vessels to implement cybersecurity measures as part of their existing safety and security protocols under the Maritime Transportation Security Act (MTSA). These measures must address vulnerabilities in systems that control or impact vessel navigation, cargo handling, and facility operations.

At a minimum, MTSA-regulated entities must:

• Conduct a cyber risk assessment.

• Integrate cybersecurity into their Facility Security Plans (FSPs) or Vessel Security Plans (VSPs).

• Implement controls to protect operational technology (OT) systems.

• Report cyber incidents within 12 hours to the National Response Center.

Why the New Rule Matters

For the first time, cybersecurity is being treated with the same level of seriousness as physical security risks in the maritime space. This regulation aligns with broader federal efforts to modernize critical infrastructure protections.

The maritime industry has long been a soft target for cyber threats due to the heavy reliance on legacy systems and the convergence of IT and OT. With ransomware attacks on the rise and international shipping playing a vital role in global supply chains, one cyber incident can disrupt commerce, damage equipment, and jeopardize safety.
