Ports are just as vulnerable to cyber-attacks as any other maritime assets.

To counter the threat, North America’s largest port, the Port of Los Angeles, unveiled an IBM-run Cyber Resilience Center in late January. It allows about 20 ports worldwide to share cyber-threat indicators and possible defensive tactics.

Los Angeles, which handles nearly 11m teu of containerised cargo per year, unveiled in 2014 a cybersecurity operation centre designed to protect it and its internal networks.

“Now more than ever, it’s vital that we secure our supply chain and critical infrastructure from the threat of intrusions, particularly those that could disrupt the flow of goods across our nation,” executive director Gene Seroka says.
