System, method, and computer program product for improving vessel navigation security

A method promoting safe navigation of ships, the method comprising:

• cyberattack detection configured to detect cyberattacks against ships' ECDIS systems and including:
• comparing data received by ECDIS and data generated by the ECDIS according to said data received,
• accordingly, determining whether an anomaly has occurred between how the ECDIS is now generating data, and how the ECDIS generated data in the past, and, at least once, alerting of a cyberattack responsive to an anomaly detected by said determining.

A computer program product, comprising a non-transitory tangible computer readable medium having computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method promoting safe navigation of ships, the method comprising:

• cyber attack detection configured to detect cyberattacks against ships' ECDIS systems and including:
• comparing data received by ECDIS and data generated by the ECDIS according to said data received,
• accordingly, determining whether an anomaly has occurred between how the ECDIS is now generating data, and how the ECDIS generated data in the past, and, at least once, alerting of a cyberattack responsive to an anomaly detected by said determining.
