The world has seen a number of high-profile maritime disasters in recent months and years, and has felt the impact of them. Over that same period, the world has seen a number of high-profile cyberattacks and felt their impact, as well. Combined, the maritime and cyber incidents have likely affected the energy sector more than any other: fuel prices often spike or plummet, and access to energy resources can become an instant source of concern, tension, or even conflict. As a wide spectrum of energy companies continue to rely on the maritime domain or even increase that reliance, they must be mindful that traditional maritime threats—like piracy, theft, and weather events—are not the only threats they face today. Maritime cybersecurity concerns are among the most potentially disruptive to energy-sector interests, and yet are among the least understood and addressed.
