Global supply chains rely on the smooth running of shipping and ports, but maritime cybersecurity is too often a low priority. One of the key components of global trade is also one of the most vulnerable to cybersecurity threats – and if such an attack was successful, it would cause huge disruption with knock-on effects for people around the world. Ports and shipping are becoming increasingly connected to the internet and that’s making them a tempting target for hackers, especially when much of the sector is simultaneously reliant on legacy technology that can be decades old. And the prospect of disruptive cyberattacks against shipping and ports isn’t just theoretical – they’re already happening. The measures that are thought for the cyber security connected with maritime transportation will need to focus on a strong development of technological systems to carry out most of the strategies from companies that are part of this industry. The maritime transportation supply chain has millions of possible threats that are not easy to follow, as hackers will look for a way to intercept the information that companies have about their ships, which certainly will help them find what they need from them. The risk of not dealing with this cybersecurity problem can become a problem for those using the sea to bring their shipments and materials to land. Companies should eliminate legacy security systems and work with more modern structures to increase security to deal with the breaching of vital information in maritime companies. Many companies will save money by avoiding getting harassed or blackmailed by hackers and other cybersecurity threats.
