Within the framework of the 19th Spanish Meeting on Cryptology and Information Security (RECSI 2026), held at the University of La Laguna (Tenerife) from 17 to 21 March, Lieutenant Commander Ferney Martínez Ossa, a member of the Security and Auditing Group (GSyA) at the University of Castilla-La Mancha and researcher at COTECMAR, presented the paper “Maritime cybersecurity: protecting digital seas” (https://doi.org/10.1007/s10207-023-00800-0).

The article represents an extension of previously published work in the International Journal of Information Security (2024), analysing the impact of digitalisation in the maritime domain and the risks associated with the interconnection of vessels, ports, and critical systems. As a result, POSEIDON is proposed as a comprehensive maritime cybersecurity framework, structuring risk management into four blocks and enhancing traceability between assets, threats, and controls, thereby facilitating decision-making and regulatory compliance.

The proposal was positively received for its practical approach and its applicability within an increasingly digitalised strategic sector.
