USCG’s Enforcement and Regulatory Mandates
Evolution of Cybersecurity Frameworks
The U.S. Coast Guard’s mandate related to cybersecurity has evolved significantly in recent years, transitioning from issuing best-practice guidelines to enforcement of stringent cybersecurity standards across the MTS. Since the development of the Maritime Transportation Security Act (MTSA) in 2002, ports have been required to create and maintain security plans. In subsequent years, particularly from 2020 onwards, cybersecurity formalized into the regulatory realm with updates to 33 CFR Part 105 and 106, compelling port authorities to identify and mitigate computer system vulnerabilities.
In response to emerging cyber threats, the USCG finalized new rules requiring comprehensive cybersecurity measures, including dedicated incident response plans, cyclical risk assessments, specific cybersecurity officer appointments, regular workforce training, and rigorous access management. Port operators are encouraged to align their programs with the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF 2.0) and NIST SP 800-82r3 for robust IT and OT security guidance. These measures are designed not only to comply with federal regulations but to cultivate a resilient cybersecurity culture within the maritime industry.
Implementation and Impact
The implementation of USCG regulations has instilled a proactive approach across maritime operators, who must now define clear roles, establish procedures for incident response, and devise ongoing improvement strategies.
