From December 3 to 5, the U.S. Department of Homeland Security (DHS), alongside the Defense Threat Reduction Agency (DTRA) and U.S. Embassy Manila, conducted a maritime cybersecurity exercise and chemical security workshop in collaboration with the Government of the Philippines. This event is part of DHS's ongoing efforts to enhance maritime cybersecurity in the Indo-Pacific region.
The exercise, held in Manila, focused on simulating cyberattacks on critical port infrastructure such as automated cargo handling systems and communication networks. Participants included Philippine public and private stakeholders working with U.S. experts to evaluate emergency procedures, coordination mechanisms, information sharing agreements, and communication plans. Observers from Australia and Japan were also present.
Under Secretary Mayorkas has emphasized building strong partnerships in the Indo-Pacific region as part of DHS's strategy to mitigate cyber risks across sectors. "The maritime domain underpins global economic security," said DHS Under Secretary for Policy Robert Silvers. He added that strengthening cybersecurity partnerships is essential for securing trade routes vital for international commerce.
Philippines Office for Transportation Security Administrator Undersecretary Crizaldo O. Nieves highlighted improvements made through policy determinations and regulatory functions in the maritime sphere over recent years. Vice Admiral Andrew Tiongson of the U.S. Coast Guard Pacific Area stressed the importance of coordinated defense against regional maritime cyber threats to ensure long-term stability.
Dr. David Mussington from CISA noted that collaborating with the Government of Philippines was beneficial for building an effective partnership and enhancing port systems cybersecurity.
Following the exercise, a workshop hosted by DHS and DTRA Cooperative Threat Reduction Program focused on chemical security risk management in marine transportation systems. Experts provided briefings on strategies to mitigate risks associated with chemical weapon proliferation.
The event was organized by DHS’s Office of Policy, CISA, USCG, U.S. Embassy Manila, and DTRA with participation from several Philippine agencies including DOTR’s Office for Transportation Security (OTS), Philippine Ports Authority (PPA), Philippine Coast Guard (PCG), Department of Information and Communications Technology (DICT), Philippine National Security Council, and ASIAN Terminal Incorporated.
