International maritime security is of paramount importance to the maritime sector, particularly seafarers. The perception and importance of maritime security have evolved and are the subject of ongoing analysis. The concept of maritime security is closely linked to potential threats that may pose a danger to crews, ships, or the cargoes they carry. These threats are also subject to change over time. Different types of threats can have different implications for maritime security. Currently, the greatest threats to the world merchant fleet come from pirate attacks, armed robbery, military operations in certain maritime regions, and terrorist operations by rebel groups in the Middle East. These threats vary in nature, frequency, and motivation in different parts of the world, and so there are certain areas that are particularly vulnerable to such threats. This paper provides an analysis of maritime security from the perspective of piracy, armed robbery, and maritime terrorism by analsying individual attacks in different regions from 2019. to April 2024. Each reported attack is broken down into various characteristics. Recurring characteristics in different and unrelated attacks are observed. This results in a pattern from which specific recommendations characteristic of individual regions is derived. The recommendations are subject to the dynamics of changes in international maritime security and should be actively modified and adapted accordingly.
