The Coast Guard has published a proposed rule to update its maritime security regulations by adding regulations specifically focused on establishing minimum cybersecurity requirements for U.S.-flagged vessels, Outer Continental Shelf facilities, and U.S. facilities subject to the Maritime Transportation Security Act of 2002 regulations.  This proposed rulemaking is part of an ongoing effort to address emerging cybersecurity risks and threats to maritime security by including additional security requirements to safeguard the marine transportation system.
