Abstract: An approach is provided for a maritime cyber risk assessment profiling tool. The tool accesses a risk profile for one or more maritime vessels, wherein the risk profile includes a plurality of attack vectors targeting a plurality of systems associated with the one or more maritime vessels, and wherein each of the plurality of attack vectors is associated with a quantified risk value. The tool retrieves a risk update from a dynamic risk data source. The tool updates the risk profile based on the risk update, including a first attack vector. The tool causes display of a risk assessment for the one or more maritime vessels based on the updated risk profile, wherein the risk assessment includes risk values assigned for a particular set of the plurality of systems including a risk value that changed based on the update to the first attack vector.
