The Department of Homeland Security (DHS) is seeking insights from commercial port stakeholders through a Request for Information (RFI) titled "Commercial Port Information and Operational Technology" under the C-PILOT program. The objective of this RFI is to identify vulnerabilities in commercial port operations, specifically focusing on Information Technology (IT) and Operational Technology (OT) systems, to enhance cybersecurity measures within the U.S. Maritime Transportation System (MTS), which is vital to the national economy and supports 13 million jobs. Participants will contribute to the development of a virtual testbed for evaluating cybersecurity readiness and identifying gaps in current protections, with the potential for interviews and site visits by DHS personnel. Interested parties are encouraged to submit their responses, including contact information and relevant experience, to MaritimePortResiliencyandSecurityStudy@hq.dhs.gov by the specified deadline.
