"Modern maritime systems are highly complex digital systems to ensure the safety and efficient operation of the shipping traffic so vital to the global economy. The vulnerabilities associated with reliance on digital systems in the maritime environment must be continuously examined. System protections must be ever ready to monitor vulnerabilities and secure maritime traffic systems. The U.S. Coast Guard must ensure the integrity of the entrances to our 'digital ports' and work to develop practical cyber security solutions to protect the nation's maritime infrastructure."
