As cyber threats targeting maritime infrastructure continue to rise, the Coast Guard has launched a groundbreaking program to assess cybersecurity risks across U.S. ports and waterways. GAO’s review shows that early progress is promising, but success hinges on stronger planning, clearer performance measures, and consistent coordination with port stakeholders. The report highlights how vulnerabilities in operational technology, port operations, and maritime supply chains could disrupt commerce and national security if left unaddressed. By identifying gaps and recommending improvements, GAO outlines what’s needed to strengthen the cyber resilience of one of the nation’s most critical transportation sectors.
