The international maritime community has embraced the need to introduce and adopt security measures to protect vital shipping, facility and port assets from terrorist attacks. This said, the maritime security environment is
dynamic and changing, and the specific nature of the threat can vary across time, from country to country, and – within an individual country – from port to port. Threat and risk assessments, and training scenarios, need to become more dynamic, and tailored to specific needs of individual ports, facilities and even vessels. To this end, we introduce a simple set of tools that may allow port and facility managers, and vessel security officers to perform their own individualized risk assessments; specifically the use of risk matrices to help identify their most likely risks, and develop security and training plans accordingly. Very simply, a risk matrix allows the user to identify how serious a risk is, based on the expected destructiveness (cost) of an event, and the probability of that event occurring.
