NATIONAL MARITIME CYBERSECURITY PLAN INFORMATION AND INTELLIGENCE SHARING T exist across other critical infrastructure sectors. The United States will promote domestic and international engagement to facilitate information sharing and best practices to build a coalition of maritime cybersecurity advocates. he unique relationships that exist between Federal, state, local, tribal, and territorial governments, industries and industry associations, and other maritime information-sharing organizations present opportunities to address broader cybersecurity vulnerabilities in the MTS. Port owners, operators, and tenants rely on nonstandard cybersecurity and information sharing solutions. Information sharing across public, private, and international maritime stakeholders relies on existing partnerships, information sharing agreements, customer needs, and regulatory requirements, all of which bolster maritime cybersecurity defense and resilience. Organizations such as Information Sharing and Analysis Centers provide a pathway to share information across the private and public sector coordinating councils. Transparency, sharing information, and intelligence, as appropriate, are keys to strengthening the integrity and resilience of the MTS. The Federal government will adapt existing policies and regulations, or create new policies and regulations, that foster the greatest transparency without sacrificing proprietary information to prevent further malicious cyberattacks. The United States will establish procedures and policies that govern the receipt and processing of maritime reports of industry cybersecurity incidents to build a coalition of maritime cybersecurity advocates. Priority Action 2: Share cybersecurity intelligence with appropriate nongovernment entities. The United States will create mechanisms to share unclassified, and when acceptable, classified information with maritime industry stakeholders, increasing access to actionable information to protect maritime IT and OT networks. Credible and actionable intelligence is required to strengthen maritime cybersecurity. Multiple private sector entities claim to be the information-sharing clearinghouse for MTS stakeholders. Overlapping membership across cybersecurity information sharing organizations creates barriers to efficiently inform MTS stakeholders of maritime cybersecurity best practices or threats. For example, CISA and private sector Priority Actions Priority Action 1: Exchange United States government information with the maritime industry. DHS, through the United States Coast Guard and the Cybersecurity and Infrastructure Security Agency (CISA), along with the Federal Bureau of Investigation (FBI) and the intelligence community, will collaborate to develop tear-line reporting and talking points for domestic and international engagement across the maritime sector.
